Cement based capillary crystalline high-performance waterproofing powder and application thereof

Abstract

The invention discloses a cement based capillary crystalline high-performance waterproofing powder and an application thereof. The cement based capillary crystalline high-performance waterproofing powder is characterized in that inorganic materials of Portland cement, quartz sand and the like serve as a base, active compound capillary crystalline master batch, polymers and other various auxiliarymaterials are added and mixed to prepare powder waterproofing materials; and the cement based capillary crystalline high-performance waterproofing powder includes, by weight, 35-50 parts of the Portland cement, 25-32 parts of the quartz sand, 2-6 parts of the capillary crystalline active master batch, 0-10 parts of calcium carbonate, 5-13 parts of talcum powders, 0.1-0.2 part of cellulose, 6-12 parts of rubber powders, 0.55-1.2 parts of water reducers, 0.1-0.4 part of power organic silicon defoamer and 4.1-5.8 parts of complexing agents. Various raw materials are uniformly stirred in a mixer to obtain the cement based capillary crystalline high-performance waterproofing powder, and the cement based capillary crystalline high-performance waterproofing powder is mixed with a certain amount of clear water to prepare the waterproofing materials. The cement based capillary crystalline high-performance waterproofing powder is simple in preparing, convenient to use and good in water resistance and anti-permeability.

Description

technical field [0001] The invention belongs to a cement-based permeable crystalline waterproof material and its application, in particular to a cement, mortar, concrete waterproof and anti-leakage material used in dams, canals, river beds, bridges, tunnels, underground, construction and other projects High-performance cement-based permeable crystalline waterproofing material. Background technique [0002] At present, there are many waterproof materials and structures developed and used. Generally speaking, they can be divided into two categories: flexible waterproof and rigid waterproof. Years of practice have proved that although traditional flexible waterproof materials such as polymer coils and coatings have the advantages of flexibility and convenient construction, they have weak adhesion to the base concrete, especially when the base is wet or seepage. It cannot be used, and it is not suitable for waterproofing the back surface and the wet base surface. On the other ...
