Abstract
The present invention relates to a cement base permeation crystal type waterproof material, a producing process thereof and a construction method thereof. The cement base permeation crystal type waterproof material is composed of the components accounting for the following proportion of total weight: 50 to 65% of cement as a principal raw material, 5.5 to 14.5% of active materials, 3.5 to 8.0% of methylcellulose as thickening agents, 2.0 to 4.5% of anhydrous citric acid as retarding agents and 20 to 40% of ground quartz sand. The permeation crystal type waterproof material is used for solving the problem of frequent cracks because of the poor anti-permeation and waterproof performance of concrete. After dry powder is scattered or water is used for stirring when newly stirred concrete is poured, the upstream face or the downstream face of a concrete structure is coated with the mixture with the functions of permeation resistance and water prevention, and tiny cracks existing in the concrete structure are blocked. The cement base permeation crystal type waterproof material has the characteristics of wide raw materials, low cost, simple producing type process, simple and convenient waterproof construction, short working time limit, no toxicity, no smell and good performance of permeation crystal, permeation resistance and water prevention. The cement base permeation crystal type waterproof material can be used for all kinds of permeation resistant concrete and waterproof, leakage blocking and moisture preventing works of concrete structures.
Description
Technical field
The present invention relates to a kind of concrete impervious, water-proof material and production technique and constructional method.
Background technology
In construction work, normal concrete impervious, water resistance is relatively poor, and problem of cracks often takes place.For reaching purpose concrete impervious, waterproof, in water-tight concrete, usually adopt the adding water resisting admixture, add methods such as cement or raising sand coarse aggregate ratio.For the sake of assurance, water-tight concrete meet water or back side needs again to do dual waterproof with materials such as coiled material, coating, it is a lot of that this improves construction cost, and cause construction period to prolong.Require anti-water termination necessary smooth, dry because of laying coiled material, make waterproof construction technology also more numerous and diverse, the comprehensive cost height, maintenance cost is also high.In addition, reaction, the time of coagulation of water-proof material are longer, are badly in need of improving early strength, with the reduction of erection time.
Summary of the invention
The present invention will provide a kind of permeable crystalline waterproofing material, solve concrete impervious, water resistance is relatively poor, and problem of cracks often takes place, and solves the low problem of water-proof material early strength.
The technical scheme of cementitious capillary waterproofing material of the present invention is characterized in that: be main raw material with cement, cement content is the 50-65% of gross weight,
All the other components are: yellow soda ash and calcium chloride active material 2-14.5%,
