Low cost cement self-leveling mortar

Abstract

The invention relates to a low cost cement self-leveling mortar, which does not contain redispersible emulsion, and is doped with zeolite powder, wollastonite powder and fly ash on the basis of a three-phase system containing silicate cement, quick hardening cement and quick hardening anhydrite so as to meet practical engineering needs. The zeolite powder, the wollastonite powder and the fly ash, under the excitation of a cement hydrate, not only have self-maintenance and crack resistance, but also play a role in replacing the cement partially so that the performance of the prepared cement self-leveling mortar is superior to that of the self-leveling mortar added with a large amount of polymer rubber powder, and the cost of the prepared cement self-leveling mortar is comparatively lower.

Description

technical field [0001] The invention is a cement-based self-leveling mortar. technical background [0002] Cement-based self-leveling mortar is a kind of dry powder premixed mortar, which is widely used for leveling indoor floors of public buildings such as residences, hospitals, supermarkets, and light industrial floors. Cement-based self-leveling mortar has the characteristics of good fluidity, self-leveling, convenient construction, and fast hardening in the freshly mixed state. The hardened cement-based self-leveling mortar has high compressive and flexural strength, high bonding strength, and volume stability. nice features. Using cement-based self-leveling mortar to level the ground construction can greatly improve the construction efficiency and quality. [0003] Most of the current cement-based self-leveling mortars are mixed with a large amount of dispersible latex powder, which not only costs a lot, but also affects the advantages of various cements.
