MORTAR FOR ENVIRONMENT-FRIENDLY WET FACING

摘要

A semi-automatic self-leveling wet finishing mortar is provided to obtain moisture control, deodorizing, anti-bacterial function, far-infrared ray radiation and electromagnetic wave protection in mortar by introducing charcoal and elvan for the composition. A semi-automatic self-leveling wet finishing mortar comprises finishing mortar powder and liquid in a ratio of 100:15 by weight, the mortar powder comprises 15.094-22.9% by weight of normal Portland cement, 65.094-72.9% by weight of elvan aggregates, 0.5-1% by weight of charcoal powder, 0.05-1% by weight of expandable calcium sulfoaluminate, 0.1-1% by weight of hard-burned lime, 0.5-5% by weight of fly ash, 0.5-3% by weight of furnace slag, 0.001-0.005% by weight of starch thickener as an underwater concrete stabilizer, 0.0005-0.001% by weight of polyethylene oxide as an inhibitor against instant-drying of surface(moisturizer) and 0.1-1% by weight of cellulose fiber which has 1,500,000 particles per gram as an anti-cracking fiber, and the liquid comprises 0.2-1% by weight of polycarbonic antiplasticizer and 99-99.8% by weight of purified water. The wet finishing mortar is placed on an On-Dol(Korean underfloor heating) structure of skyscraper apartment or architecture by grouting method.
