Inorganic waterproof cementitious material and preparation method thereof

Abstract

The invention discloses an inorganic waterproof cementitious material. The inorganic waterproof cementitious material is characterized by comprising the materials in parts by weight: 35-55 parts of ash and / or decarburized slag, 10-30 parts of blast furnace slag / mineral powder, 8-16 parts of slag and / or coal ash, 4-8 parts of carbide slag, 0-10 parts of cement clinker, 4-8 parts of gypsum, 0-5 parts of lime stone and 0.5-5 parts of booster. All materials adopted by the inorganic waterproof cementitious material are inorganic materials, and aim at overcoming the defects generated by organic matters contained in polymer waterproof mortar. Thus, the inorganic waterproof cementitious material is good in weather fastness, not easy to age, good in affinity with a base layer, convenient to construct, and long in service life; and no harmful gas is released in the constructing and using processes.

Description

technical field [0001] The invention relates to the field of building waterproof materials, in particular to an inorganic waterproof gel material and a manufacturing method thereof. Background technique [0002] At present, building waterproof materials mainly use organic or waterproof materials mixed with organic polymers, including waterproof membranes, waterproof coatings, rigid waterproof materials, and building sealing materials. Among them, waterproof membranes include synthetic polymer membranes, polymer modified asphalt waterproof membranes, and asphalt waterproof membranes. Waterproof coatings include synthetic polymer waterproof coatings, polymer modified asphalt waterproof coatings, and asphalt-based waterproof coatings. Rigid waterproof materials are waterproof materials mixed with admixtures such as polymers, including waterproof concrete and waterproof mortar. [0003] Organic waterproof materials generally have defects such as poor weather resistance, easy a...

AI Technical Summary

Problems solved by technology

[0011] The object of the present invention is to provide a kind of inorganic waterproof gelling material and its manufacture method, to solve the problem of adding organic matter (such as polymer) in the waterproof material, the poor affinity between organic matter and inorganic matter such as cement, and the poor weather resistance of organic matter. The dry and wet deformation of concrete or mortar, temperature deformation and structural displacement will cause cracks to cause water seepage and ultraviolet aging, and the service life is short.
