Inorganic powder capillary crystalline waterproof coating material

Abstract

The invention discloses an inorganic powder infiltration crystalline water-proof material which consists of 45 to 55 portions of 600#silicate cement, 20 to 25 portions of ultra-thin quartz sands, 25 to 30 portions of master batches, 1 to 5 portions of effective retarding water reducers and 1 to 5 portions of macromolecular tougheners and is manufactured by feeding the materials into a stirrer to be uniformly stirred. The inorganic powder infiltration crystalline water-proof material is characterized by having the advantages of secondary anti-permeability capacity, durable water-proof performance, high sticking performance, acid resistance and alkali matter resistance; besides, the inorganic powder infiltration crystalline water-proof material have the capacity of growing an insoluble crystal in the pores and the micro cracks of a concrete substrate to plug the pores and the micro cracks, thereby improving the anti-permeability capacity of the concrete and achieving the goals of anti-permeability and anti-leakage. The inorganic powder infiltration crystalline water-proof material can be broadly applied to the water-proof projects of railways, roads, ports and docks, culverts, dams and pools as well as large underground projects.

Description

technical field The invention belongs to the technical field of building waterproof engineering, and relates to a waterproof coating material. Specifically, it is a waterproof and waterproof coating for flat and vertical surfaces of concrete structures such as highways, landfills, bridges, tunnels, and underground buildings. The leaking inorganic powder penetrates the crystalline waterproof coating. Background technique Concrete is a porous substance, and capillary pores and microcracks are the root causes of concrete leakage. Such as caused by deformation, including shrinkage, expansion, uneven subsidence, etc. caused by changes in temperature and humidity; caused by direct stress from external loads (dynamic and static loads). At present, most of the cement-based waterproof materials commonly used are surface-sealing waterproofing agents. The waterproof effect only acts on the surface and cannot automatically and deeply penetrate into the interior of the structure. The wa...

AI Technical Summary

Problems solved by technology

This kind of waterproof coating is made of Portland cement or ordinary Portland cement and refined quartz sand. After actual construction and application, it is found that this cement-based permeable crystalline waterproof coating is easy to stick to concrete because it is a rigid coating. However, after bonding, rigid cracks can still be produced, and the cracks become channels for water seepage and leakage, and cannot achieve waterproof effect
