Description
Technical field
The present invention relates to concrete field, more particularly to weather-proof geo-polymer pervious concrete by force of a kind of morning.
Background technology
Pervious concrete is a kind of special concrete, is generally made of bonding agent, coarse aggregate, water and additive, through special
Inside prepared by technique includes continuous aperture and the engineering material with high water seepage function, can be used for Water warfare, permeable road
Face, acoustic absorption and other civil engineerings.Currently, pervious concrete is divided into cement pervious concrete and the permeable coagulation of macromolecule
Soil：(1) cement pervious concrete is made simply, at low cost, durability is good, is current using portland cement as cementitious material
The maximum a kind of pervious concrete of dosage, but the hydration and hardening of cement is strong to humidity, the temperature dependency of maintenance, and it is permeable mixed
For solidifying soil due to porous structure characteristic, water holding capacity is poor, the low strength in the case where maintenance should not ensure, it is difficult to solve intensity and
Contradiction between coefficient of permeability；Simultaneously portland cement resources of production, energy consumption is big, environmental pollution is serious, from environmentally friendly angle
Degree considers, needs to find more suitably cementitious material and cement is replaced to make pervious concrete.(2) macromolecule pervious concrete be with
Macromolecule is as cementitious material.The pervious concrete includes mainly pitch pervious concrete, two kinds of resin pervious concrete.Pitch
Permeable concrete is compared with cement pervious concrete, this kind of pervious concrete intensity is high, but pitch is as organic cementitious material
It is poor to the adaptability of weather, it is easier aging under the influence of air, especially when temperature is promoted, the permeable coagulation of pitch
Soil can soften, and bituminous liquids can be caused to flow out, and the intensity and water penetration for eventually leading to pervious concrete all reduce, in addition cost phase
To higher；Resin permeable concrete is compared with pitch pervious concrete, cement pervious concrete, its more water proof and wearable, but
Its is of high cost, while easy to aging.
It can be seen that a kind of significance of research and development novel morning weather-proof geo-polymer pervious concrete by force, base of the present invention
It is researched and developed in this.
Invention content
For the existing limitation of traditional pervious concrete (cement pervious concrete, macromolecule pervious concrete) and insufficient,
In conjunction with the characteristics of mineral polymer and advantage, the present invention proposes a kind of morning weather-proof geo-polymer pervious concrete by force, with alkali
Excitation steel slag polymer is cementitious material, is the technical thought gathered materials and prepare pervious concrete with simple grain grade aggregate, it is intended to solve
Pervious concrete curing condition requires height, and early strength is low, is easy to dusting, and the technical barriers such as weatherability difference are " sponge city "
Offer technical support is be provided.
To realize that above-mentioned target, the specific technical solution of the present invention are as follows：
A kind of morning, weather-proof geo-polymer pervious concrete, in parts by weight meter included by force：40-50 parts of slag, Blast Furnace Ore
25-45 parts of slag, 10-20 parts of zeolite, 5-10 parts of silicon ash, 1-5 parts of nano-calcium carbonate, 0.1-0.5 parts of water-reducing agent, 3-6 parts of exciting agent,
400-500 parts of stone, 33-40 parts of water.
Preferably, concrete 3d compression strength plays 60% or more, and 28d compression strength is more than 30MPa.
Preferably, the slag is after grinding, specific surface area 330m2/ kg or more, blast-furnace cinder grade are S95 grades,
SiO in silicon ash2Content at least 85%.
Preferably, the nano-calcium carbonate particle size range is between 20-60nm.
Preferably, the zeolite is 5A zeolites, is to use Ca2+Na during exchange 4A is zeolite structured+It is obtained that there is the apertures 5A
Type A zeolite.
Preferably, the exciting agent is waterglass, can adjust modulus by alkali metal hydroxide.
Preferably, the stone is single particle size rubble.
Preferably, the water-reducing agent is naphthalene system or polycarboxylate water-reducer, 15% or more water-reducing rate.
The present invention uses main raw material(s) of the slag as pervious concrete, effectively improves the utilization of trade waste
Value, alleviates environmental pressure；The incorporation of zeolite, reduces the degree of the geo-polymer accumulation of salt in the surface soil, and high-silicon high aluminium contributes to
The promotion of water coagulation soil intensity；The incorporation of silicon ash improves the density of concrete；Nano-calcium carbonate can not only be accelerated to react
Process improves early strength, can also be effectively increased whole consistency, reduces cement amount.The permeation coefficient of permeable concrete is high,
The features such as early strength is big, low to curing condition requirement, and later strength is high, reducing causes since pervious concrete maintenance is not in place
Dusting, the problems such as intensity is low.
Using the above scheme, the invention has the advantages that：
Early strength is high, and 3d compression strength plays 60% or more, and 28d compression strength is more than 30MPa, and it is permeable mixed to meet C25
Coagulate the requirement of soil.The present invention not only has excellent water penetration, and early strength is high, also relatively low to curing condition requirement, has avoided
The drawbacks such as sand；Accumulation of salt in the surface soil problem existing for geo-polymer is inhibited to a certain extent simultaneously.The present invention is " sponge city "
Offer technical support is be provided.
