Description
Technical Field
The invention relates to the technical field of concrete, in particular to modified rubber pervious concrete and a preparation method thereof.
Background
The waste rubber product is a macromolecular elastic material which is difficult to dissolve and naturally decompose under natural conditions, and the waste rubber is very difficult to treat due to the chemical, biological and physical resistance of the waste rubber. The waste rubber particles are used as the admixture for the cement concrete, so that the method is a resource-saving and environment-friendly utilization approach, not only can a large amount of waste rubber be utilized, but also compared with the traditional concrete, the rubber concrete has the characteristics of high impact resistance, good wear resistance, excellent crack resistance and good heat and sound insulation effects, and the compressive strength is reduced to a certain extent compared with the traditional concrete. Chinese patent application CN109437729A provides a frost crack resistant concrete, which comprises the following raw materials: the invention mainly adds the modified rubber powder to prepare the concrete, so that the concrete has good frost resistance and crack resistance, but the compression resistance of the concrete doped with the modified rubber powder is reduced.
The pervious concrete is a porous concrete with continuous pores, which is prepared by aggregate with specific gradation, cement, water, an additive, an admixture and the like according to a specific proportion through a special process. The common pervious concrete is mostly provided with a cellular structure with uniformly distributed pores formed by coating a layer of thin cement slurry on the surface of coarse aggregates and mutually bonding the thin cement slurry, so that the strength is lower and the durability is poorer due to the structural characteristics of the concrete. Zinc stearate used as a vulcanization activator and a softener in rubber is a hydrophobic material, impurities are more on the surface of the rubber, and if rubber aggregates are directly doped into concrete, the problems of poor bonding property between the rubber and a cement interface, reduced strength of a concrete finished product and the like are caused.
Therefore, it is necessary to develop a pervious concrete with a modified rubber incorporated therein to enhance the compressive strength and freezing resistance thereof.

The pervious concrete as a porous material has larger porosity compared with common concrete, has lower compressive strength, and can cause a material sample to be completely frozen in a plurality of cycle periods under a freezing condition due to the open pore structure characteristic. After the modified rubber is treated and mixed into the pervious concrete, the modified rubber in the pervious concrete can play a certain role in buffering when the pervious concrete deforms under the action of stress because the rubber has high elasticity. In addition, the pervious concrete is of a porous structure, and the strength of the pervious concrete mainly depends on the binding power among aggregates, so that the pervious concrete can serve as fine aggregates after being doped with the modified rubber and play a certain skeleton role, thereby improving the strength of the pervious concrete.
