A Mortar Composition of Crack-Reducing Type for High-Performance Floor and Constructing Methods Using Thereof

摘要

The present invention is based on 100 parts by weight of cement, 250 to 500 parts by weight of sand; 3 to 30 parts by weight of a mineral shrinkage reducing agent; 3 to 30 parts by weight of a binder; 0.01 to 0.3 parts by weight of a glidant; Cellulose fiber 0.1 to 1 part by weight; And it relates to a high-performance floor mortar composition comprising 0.5 to 2 parts by weight of an admixture. The high-performance floor mortar composition, specifically, the crack-reducing high-performance floor mortar composition according to the present invention can improve the working environment and reduce environmental pollution while increasing physical properties such as strength and fluidity and reducing the occurrence of cracks. have.
