Abstract

The invention relates to a polymeric cement gravity flow leveling material prepared from silicate cement, polymer emulsion powder, high-alumina cement, mineral blending materials, high efficiency water reducing agent, defoaming agent, and quartz sand and with right weight ratio through finite process, material possesses good mobility, stability, high early stage folding and compression resistant strength, thus can be widely applied in ground surface leveling and mending of old ground surface, sand streak ground surface and ground surface with less qualified construction.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a ground self-leveling material. Background technique [0002] With the development of modern industrial technology and production, the requirements for cleaner production are getting higher and higher, requiring the workshop floor to be corrosion-resistant, clean, wear-resistant and smooth. In addition, during the construction of the building ground, problems such as uneven ground, sand, pockmarked surface, and damage often occur due to various reasons. In response to the development and requirements of ground engineering, a ground self-leveling material has been widely used. The self-leveling material is mixed with water to form a highly fluid and stable slurry, which can be self-leveled when poured on the ground. After hardening, a smooth and flat ground can be obtained. . It can effectively replace the traditional ground method, and can be used to rep...
