Description

A kind of waterproof anti-permeability agent and the water proof anti-seepage concrete that utilizes waterproof anti-permeability agent to make
Technical field
The present invention relates to a kind of water proof anti-seepage material, specifically a kind of waterproof anti-permeability agent and the water proof anti-seepage concrete that utilizes waterproof anti-permeability agent to make belong to building material field.
Background technology
Concrete itself is porous, be not the institute aggregate that had living space with solid-state filling wherein.Cement can produce hole through hydro-combination process, also can produce bubble in the concrete whipping process.When free-water after being combined in the space in the concrete, the concrete structure of final molding just has water permeability, water is under static pressure or capillary action like this, will enter concrete structure, As time goes on concrete structure is produced and destroy, the structure outward appearance also can be outmoded gradually, and is in eclipse and produce stain and cause and fade.Although the concrete production is selected the high-quality aggregate for use, cement mixes and stirs with suitable proportion and fully maintenance, and hole intrinsic in the concrete still can't be eliminated fully, makes buildings can not reach real waterproof.
At present, for reaching the many impervious agents that in concrete, add of waterproof impervious characteristic, impervious agent is mainly used in the sand that substitutes in the concrete, the preparation impervious concrete, improve concretely from waterproof and anti-permeability performance, impervious concrete is mainly used in the waterproof on pipeline hole, leak stopping and the ground of toilet in the building, kitchen, toilet.Impervious agent can replace sand mix concrete, in impervious agent and concrete layer reaction process, the atom of macromolecular compound connects into linear and to have longer branching portion netted in its main component, impervious agent generally all is to present disorderly to the three-dimensional arrangement that distributes, be clouded in the macromolecular structure of concrete layer, and stop up concrete capillary channel fully, make cement have hydrophobic nature, improve concrete impervious ability, increase its degree of compactness and impermeability.Impervious agent can not fusion in when heating, can only deliquescing; Can not in any solvent, dissolve, can only microswelling; So can effectively remedy various slight flaws in construction process.But there is the construction technology complexity in traditional waterproof anti-permeability agent, and barrier performance is poor, needs professional's operation, the shortcoming that cost is high.
Summary of the invention
The technical problem to be solved in the present invention is at the deficiencies in the prior art, and the waterproof anti-permeability agent that a kind of cost is low, barrier performance is good is provided.
Another technical problem that the present invention will solve provides a kind of water proof anti-seepage concrete that utilizes above-mentioned waterproof anti-permeability agent to make.
For solving the problems of the technologies described above the present invention by the following technical solutions:
A kind of waterproof anti-permeability agent is made up of the material of following weight ratio: cement: condensing agent: swelling agent: flyash: polypropylene fibre=1:0.004-0.006:0.07-0.097:0.01-0.025:0.0035-0.0055.
Below be further improvement of the present invention:
Described waterproof anti-permeability agent is made up of the material of following weight ratio: cement: condensing agent: swelling agent: flyash: polypropylene fibre=1:0.0054:0.0876:0.0150:0.0045.
A kind of water proof anti-seepage concrete that adopts above-mentioned waterproof anti-permeability agent is made up of the material of following weight ratio: waterproof anti-permeability agent: rubble: water=1:0.8-1.5:0.2-0.3.
Further improve
Described water proof anti-seepage concrete is made up of the material of following weight ratio: waterproof anti-permeability agent: rubble: water=1:1.5:0.3.
The present invention adopts technique scheme to have the following advantages: the seepage control and crack resistance concrete that waterproof anti-permeability agent is made directly admixture is done bed course with microlith, reduced construction link, seepage control and crack resistance concrete and basic unit's cohesive force are strong, do not shrink, do not come off, be highly suitable for office building, residential building toilet, kitchen, scrub a pipeline hole cram ground waterproof etc.; Alternative " three little " (refer to kitchen, toilet, do the wash between) waterproof is brushed with third logical sequence of laying and institute and is gathered dried fat etc.; Cost is low, construction technology is simple, strong operability, and nontoxic, do not fire, not quick-fried.
Below in conjunction with embodiment technical scheme of the present invention is described further.
