Cement-based mortar composition with self-leveling for underfloor heating in buildings

摘要

The present invention relates to a cement-based mortar composition having self leveling used for heating a building on-floor floor which is a hot water pipe.;The cement mortar composition of the present invention is 50 to 200 parts by weight of limestone powder, 5 to 50 parts by weight of gypsum, 10 to 70 parts by weight of alumina hydraulic material, 50 to 200 parts by weight of aggregate, 0.1 to 10 parts by weight of a cement And 0.1 to 10 parts by weight of the middle agent, 1 to 20 parts by weight of the water-retaining agent and 0.1 to 50 parts by weight of the coagulation delay agent.;Such a composition is particularly effective in reducing cracking and peeling of heating pipes, improving surface horizontality, and providing lightweight far infrared rays.
