Problems solved by technology

Traditional artificial floor plastering can no longer meet the requirements of this type of floor decoration. Even if traditional artificial plastering is used and the existing thin-layer self-leveling mortar is used, not only the cost is expensive, but also the construction period will be greatly extended

Abstract

The invention belongs to the technical field of building materials and specifically discloses binary system quick-drying thick-layer cement self-leveling mortar. The binary system quick-drying thick-layer cement self-leveling mortar is mainly composed of the following ingredients (by weight): 25-30% of ordinary Portland cement, 5-8% of sulfoaluminate cement, 1.5-3% of calcium oxide, 2-5% of fine sinking beads and 40-45% of dried river sand of 12-140 meshes, etc. According to the binary system quick-drying thick-layer cement self-leveling mortar, one-time construction thickness reaches 50 mm, existing ground artificial plaster can be directly replaced, construction speed is fast, construction period is greatly shortened, and flatness is high. After construction, the ground can be directly coated with floor paint, and wooden floorboards and PVC boards can be paved or large-sized flat bricks can be directly paved by the use of a glue for tiles by a thin-layer full adhesion method.

Description

technical field [0001] The invention relates to the technical field of building materials, and specifically discloses a binary system quick-drying thick-layer cement self-leveling mortar. Background technique [0002] Self-leveling mortar is a dry-mixed powder material composed of a variety of active ingredients, which can be used after mixing with water on site. Self-leveling mortar is a kind of fluid mortar after being mixed with water. After being poured into the ground, this mortar can automatically level and level the ground to obtain a high-level base surface. Its hardening speed is fast, and the construction of follow-up projects (such as wood flooring, diamond boards, etc.) is quick and easy, which is unmatched by traditional manual leveling. [0003] Self-leveling mortar was developed in the 1970s. How to accurately control shrinkage and expansion has always been a major difficulty faced by self-leveling mortar. To overcome this difficulty is closely related to the...
