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

Abstract

The invention discloses an inorganic waterproof coating. The inorganic waterproof coating is prepared by conveying the following raw materials to a stirrer to be stirred uniformly: 45-55 parts of 800# Portland cement, 20-25 part of extra-fine quartz sand, 25-30 parts of master batch, and 1-5 parts of an efficient coagulation-delaying type water reducing agent. The inorganic waterproof coating has the characteristics of having secondary seepage resistance, long-lasting waterproof performance, strong bonding, acid corrosion resistance and alkaline corrosion resistance, can grow insoluble crystals in capillary pores and microcracks in the concrete matrix to block the capillary pore passages and microcracks, in order to improve the concrete seepage resistance and reach the purposes of seepage resistance and leakage proofing. The inorganic waterproof coating can be widely applied to waterproof projects for metros, roads, ports, culverts, dams, pools and large-scale underground projects.

Description

technical field [0001] 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. Leaking inorganic waterproof coatings. Background technique [0002] 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 waterproof effect is no...
