BIO-COATING COMPOSITION FOR INDOOR AIR PURIFICATION USING ZnO PHOTOCATALYST

摘要

Provided is a loess coating for a concrete breast wall, which has an eco-friendly coating applied to the concrete breast wall. The present invention also relates to a concrete surface treatment method using the same and a concrete surface treatment structure. More particularly, the loess coating comprises: 0.1 to 2 wt% of ZnO nanopowder; 17 to 23 wt% of loess powder; 3 to 4 wt% of illite powder; 2 to 4 wt% of silicate; 27 to 28 wt% of magnesium oxide powder; 13 to 14 wt% of magnesium chloride powder; and 32 to 33 wt% of water. The concrete surface treatment method comprises a concrete washing step, a concrete pretreatment step, a coating application step, and a finish treatment step. The concrete surface treatment structure has a primer application layer (11), a loess coating layer (12), and a surface layer (13) on the surface of concrete (10).;COPYRIGHT KIPO 2016
