Permeable crystalline type concentrating agent prepared from construction waste micro-powder and method thereof

Abstract

The invention provides a permeable crystalline type concentrating agent prepared from construction waste, aiming at insufficiencies of high raw material cost and unsatisfactory mechanical properties of existing cement-based permeable crystalline type waterproofing materials, and the agent comprises regenerate micro-powder, cement, quartz sand, active silicon additive, complexing agent and CaO, wherein the regenerate micro-powder is obtained through crushing, screening and ball milling the waste concrete of the construction waste. The product provided by the invention and method thereof not only realizes recycling of the construction waste, but also provides a permeable crystalline type waterproofing and grouting material with low cost, and the material has excellent mechanical properties and good stability, and can be used as casting materials for buildings and admixtures of consolidating materials of reservoirs and banks weak interlayers.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a osmotic crystalline concentrate with waterproof and anti-seepage functions. Background technique [0002] Osmotic crystalline concentrator is a kind of osmotic crystalline waterproof material, which was originally invented by German chemist Lawrence Jackson in the practice of solving water leakage from cement ships during World War II. After the Second World War, the rapid economic growth of Europe and Japan made the engineering utilization of this material continue to expand, and the product also developed from the early German VANDEX (stable water) brand to the famous Canadian XYPEX (Sypers) concentrated agent. [0003] Commercially available cement-based permeable crystalline waterproofing materials usually add some chemically active organic materials to the cement, which are relatively expensive. Its mechanism is: using the inherent chemical properties and porosity of ce...

AI Technical Summary

Problems solved by technology

[0005] In summary, the existing cement-based permeable crystalline waterproof materials have high raw material costs, and their mechanical properties are unsatisfactory. Usually, they can only be used for waterproofing treatment, and cannot be used as pouring concrete and grouting materials.
