A paving material for the large-span bridge is prepared from thioaluminate and/or silicate cement, emulsion of polymer resin or the water-dispersed polymer adhesive powder, fine sand, broken stone, inorganic modifier and reinforcing fibres. Its advantages are high strength, adhesive and antiwear nature, and low shrinkage.
Description
One, the technical field
The invention relates to a road construction surface layer material, in particular to a composite material for paving a bridge deck, and specifically relates to a large-span bridge paving material.
Second, background Art
The large-span bridge refers to a bridge spanning big rivers, big rivers and seas, an urban viaduct and the like. The bridge deck is mostly composed of a plurality of hollow steel boxes, commonly called steel box girders, and the bridge with the structure is sometimes called steel box bridge for short. Due to the large span, the vertical amplitude of the bridge deck is also large, for example, when the bridge deck is loaded, the design of the central area of the bridge deck allows the amplitude to reach as much as 1 meter (namely, the bridge deck is allowed to sink 1 meter); the steel has poor heat compatibility, the surface temperature of the steel changes along with the difference of the environmental temperature, the hollow structure is not ventilated, and the temperature of the bridge deck is more than 10 ℃ higher than that of the common steel bridge deck in summer. All of these means that there is a specific requirement for the paving material of the bridge deck of the large-span steel box bridge, firstly, the thickness of the paving surface layer is required to be less than 8cm in order to avoid the overload caused by the increase of the dead weight, and meanwhile, certain flexibility, stability at high temperature and low temperature, crack resistance and fatigue resistance are required on the premise of meeting the strength, sealing performance and the like, and the paving material can be synchronous with the thermal expansion and cold contraction of the steel without fracture.
The steel bridge deck pavement material starts to use cast asphalt concrete, later uses asphalt mastic (SMA), and the latest popularization in China at present is epoxy asphalt concrete, wherein a thin adhesive layer (epoxy asphalt) is firstly coated on a steel plate coated with an anti-rust layer, an epoxy asphalt mixture (lower layer) is paved on the steel plate, then a thin adhesive layer (epoxy asphalt) is coated on the steel plate, and finally an upper layer (epoxy asphalt mixture) is paved. Needs on-site preparation and various mechanical devices, and has complex construction. In addition, the inherent defects of the asphalt still exist, namely, the asphalt is easy to be oxidized and degraded, and has poor water resistance, slip resistance and durability, and the high-temperature anti-rutting performance and the low-temperature anti-cracking performance are also poor.
The method enters the high-speed development period of the large-span bridge after the self-reformation and the opening of China. In a large number of large-span steel box bridges which are built, along with the increase of service life, bridge decks are damaged quite a lot, some are repaired, some are repairing, and some are about to be repaired. Therefore, the bridge deck pavement material has become one of the key technologies for constructing the large-span steel box bridge, is highly valued by the international engineering and academic circles, and is a worldwide engineering technical problem. The bridge deck pavement material of the large-span steel box bridge suitable for the national conditions of China is researched and developed at present, and is an urgent matter for the large-span steel box bridge which is built or is being built or is about to be built.
Third, the invention
The invention relates to a composite material, which is intended to be used for paving a bridge deck of a large-span steel bar bridge. The composite material comprises the following components in percentage by weight:
30-90% of sulphoaluminate and/or silicate hydraulic material
0.1 to 40 percent of polymer resin emulsion or water-redispersible polymer rubber powder
6 to 60 percent of fine sand
3 to 30 percent of broken stone
0.1 to 15 percent of inorganic modifier
0.5 to 6 percent of reinforcing fiber
The preferable weight percentages of the components are 45-80%, 3-30%, 10-50%, 5-20%, 0.5-10% and 1-5% in sequence.
Hydraulic materials are hydraulic binders, commonly known as cements. The present invention uses either sulphoaluminate cement or portland cement. The sulphoaluminate cement belongs to early strength cement, namely, the sulphoaluminate cement can be quickly set and hardened, and in the conventional technology, when a concrete product needs to compensate shrinkage or the shrinkage of the concrete product needs to be strictly controlled, adding a proper amount of sulphoaluminate cement is one of the technical means for solving the problem. Because the sulphoaluminate may react with calcium sulphate to form an expandable ettringite mineral phase. The invention fully exerts the functions of early strength and shrinkage compensation through compounding. In the invention, the two can be used independently, but the two are preferably used in a compounding way, and the early strength portland cement (also called as portland quick-hardening cement) is preferred to be compounded.
The redispersible polymer powder is also called redispersible powder resin, and is a powder resin prepared by spray drying polymer resin emulsion, and the powder resin can be recovered and redispersed to form resin emulsion after being added with water, so that the redispersible powder resin is called redispersible powder resin. In the application, acrylate emulsion (pure acrylic emulsion), styrene-acrylate emulsion (styrene-acrylic emulsion), styrene-butadiene (polymer) emulsion (styrene-butadiene emulsion), carboxylic styrene-butadiene emulsion, epoxy emulsion and the like can be used, or the emulsion is subjected to spray drying to obtain pure acrylic rubber powder, styrene-butadiene rubber powder, carboxylic styrene-butadiene rubber powder, epoxy rubber powder and the like. The acrylic esters include methyl, ethyl, butyl, octyl, etc. of acrylic or methacrylic acid. The emulsion or the rubber powder can be used alone or in combination of two or more. Preferably pure acrylic emulsion or/and styrene-acrylic emulsion or/and carboxyl styrene-butadiene emulsion, or pure acrylic rubber powder or/and styrene-acrylic rubber powder or/and carboxyl styrene-butadiene rubber powder. If the rubber powder is used, the rubber powder can be directly and uniformly mixed with other components; if the emulsion is used, the emulsion is separately packaged and forms a two-component product together with other uniformly mixed components, and the emulsion is added when being prepared on a construction site.
The fine sand and the crushed stone function as aggregate, namely, the commonly used graded building material, and the fine sand comprises river sand, sea sand, mountain sand and the like.
The inorganic modifier can be active silica or/and fly ash or/and volcanic ash or/and geopolymer. Preferably active silica or/and geopolymers.
The reinforcing fiber is commonly used in concrete, such as steel (stainless steel) fiber, natural fiber, organic polymer fiber, carbon fiber, glass fiber, and the like, and in the application, polymer fiber or/and carbon fiber or/and glass fiber is preferred, and alkali-resistant or alkali-resistant glass fiber or/and polypropylene fiber is preferred.
One or more than two of the following components can be selectively added into the paving material to improve the related specific performance
0.1 to 4 percent of defoaming agent
0.1 to 4 percent of wetting agent
0.1-3% of coagulation regulator
0.01-2% of plasticizing rheological agent.
The defoaming agent comprises octanol, pentanol, tributyl phosphate, polyethylene glycol fatty acid ester and the like.
The wetting agent comprises polyacrylic acid sodium salt and C8～C20Alkylphenol ethoxylates and the like.
The setting regulators include sodium borate, boric acid, citric acid, lithium carbonate, and the like.
The plasticizing rheological agent comprises naphthalene sulfonate, polycarboxylate, sulfonated melamine formaldehyde resin and the like.
The paving material is simple to prepare, and the components are mixed and stirred uniformly according to a certain proportion to obtain a dry stirring material, and the dry stirring material is sealed and packaged. For a two-component product, the liquid components are added at the time of preparation at the construction site. The paving material is convenient to construct, the dry mixed material is added with water and stirred to obtain slurry, and a well-known casting machine or spreading machine is used for paving the bridge deck or repairing the road surface of a high-grade highway or an expressway.
The compounding is one of the main approaches for scientific development and application of materials, good micro-grading is formed by reasonably adjusting parameters such as the mixing amount proportion and the like, the compounding effect among all components can be maximized, such as the micro-aggregate effect, the morphological effect, the interface effect, the volcanic ash effect, the ball lubrication effect and the like, so that the mutual superposition is realized, the synergistic enhancement effect of 1+2 or more than 3 is realized by the total compounding effect, and the overall comprehensive performance is improved to adapt to the requirements of working conditions.
The technical performance index of the composite material is closely related to the internal microstructure, density, uniformity and the like of the composite material.
The modification of the polymer is multifaceted and mainlyhas the functions of crosslinking and densification. The cross-linking action on one hand excites and regulates the hydration reaction of inorganic hydraulic materials, the polymer film-forming self-crosslinking reaction, on the other hand, the polymer molecules and inorganic mineral hydration products such as cement and the like generate chemical bonding, namely the ionic bonding between carboxyl and calcium ions generated by the hydration of the cement, polymer molecular chains generate cross-linking through the calcium ions to form a network, so that the interface bonding strength is improved, crystals and colloids of expanded calcium sulphoaluminate or calcium silicate are formed by whiskers, a three-dimensional space network structure is formed, the mechanical property of the whole composite material is enhanced, the mixture has surface thixotropy, the flexibility and the stirring stability are improved, the opening time is prolonged, the early solidification, the high strength, the volume shrinkage compensation and the new and old interface binding power of the mixture are promoted; the abrasion resistance of the surface of the raw material is improved, the carbonization speed of concrete is slowed down, and the durability and the service life of the paved road surface are ensured.
The crosslinking is also: the carboxylate-containing polymer produces an adsorption effect with the cement and silica on the surface of the sandstone aggregate, increasing the crosslinking among various particles in the whole material system. Thus, divalent and trivalent ions can form characteristic bridging bonds between organic polymer chains, thereby enhancing the overall strength of the material.
The densification effect is derived from a ball lubrication effect, so that the friction force among component material particles is reduced, the electric polarity of a dispersion medium in a material system is changed, the agglomeration or flocculation structure ofthe particles is reduced, and the compactness of the whole material is increased.
The hydraulic material selected for this application, unlike portland cement, releases only a small amount of free calcium oxide during hydration. This property can provide product designers with excellent resistance to chemical attack for concrete requiring low porosity and is a major reason for eliminating or reducing efflorescence. The free calcium oxide has two special functions, and the content of the free calcium oxide is further reduced in the action process, so that the possible alkali aggregate reaction and alkali corrosion to the reinforcing fiber are reduced, and the resistance and the comprehensive performance of the product are improved. These two specific functions are to hydrolyze the ester groups in the polymer component to form carboxyl groups, which functions as described above; secondly, the product of the invention is used as a composite alkali activator together with other alkaline substances to enable the geopolymer (aluminum silicon oxide compound) to generate polymerization reaction to finally form a network-shaped inorganic polymer, which takes ionic bonds and covalent bonds as main materials and van der waals bonds as auxiliary materials, while the traditional cement takes van der waals bonds and hydrogen bonds as main materials, so the performance of the product is superior to that of the traditional cement material.
The inorganic modified active silicon dioxide can be used in cement clinker mineral C3S (tricalcium silicate) and C3Surface adsorption of A (tricalcium aluminate) hydrate, formation of complexes, acceleration of hydration reactions and reaction with cement hydration products Ca (OH)2The reaction is generated: the reaction is absorbing H2At the same time, the cement hydration reaction products Ca (OH) are consumed2This further promotes the hydration of the mineral. The amorphous active silicon dioxide has an average particle diameter of 0.15 to 0.20 μm and a specific surface area of 15000 to 20000m3Kg, has extremely strong surface activity to improve the comprehensive performance of the product, and improve the wear resistance, the scouring resistance, the corrosion resistance, the penetration resistance, the freezing resistance,Early strength performance, improved strength and durability of the product, and can provide users and designers with extremely high product stability.
The reinforced fiber can improve the overall flexibility, crack resistance, impact resistance, freeze-thaw resistance and fatigue resistance of the pavement. The paving material is suitable for thin layer paving of large-span steel box bridge floors, thin layer paving of non-steel box bridge floors and repairing of damaged pavements of high-grade highways and expressways.
The test of the paving material after air curing for 28 days is carried out on a test block with the thickness of 5cm, the compressive strength is more than or equal to 40MPa, the breaking strength is more than or equal to 6MPa, the compression-shear strength is more than or equal to 4MPa, the bonding strength (with the steel surface) is more than or equal to 3.5MPa, the drying shrinkage rate is less than or equal to 0.1 percent, and the wear resistance (weight loss) is less than or equal to 0.7 percent.
