PURPOSE: Provided is an environmental effective composition for construction finishing materials having far infrared ray and anion emission, sterilization and electromagnetic shielding. CONSTITUTION: The composition for construction finishing materials comprises 25-59wt.% of agalmatolite, 1-23wt.% of additives for property improvement, 37-42wt.% of elvan and 3-10wt.% of white cement. The finishing materials are prepared by the following steps of: removing water from agalmatolite, comprising pyrophillite, kaolinite and sericite, by drying at 100-110deg.C for 3-4hrs with hot blast; mixing agalmatolite with additives and grinding to be a size of 40micrometer, wherein the additives include impact relaxant, shrinkage and expansion relaxant, hardening accelerator, viscosity modifier, and optionally ferrite and magnetite; adding elvan(<=2mm size) containing albite, quartz and sericite, and white cement containing calcium silicates to mixtures.
