Evaluation of Durability and Anti-soiling Performance on Grinded Faced Pre-cast Concrete Panel including Limestone and Quartz glass

Abstract

This paper is desclibed about grinded faced pre-cast concrete panel including natural stones. We verified appropriate stones in concrete by alkali aggregate reaction test and chosed limestone and quartz glass as seed stones. Clear membrane materials covering surface were evaluated by performance of holding stones and attaching to surface by dipping test in hot water, cycle test with hot and cool conditions, and freezing and thawing test. We chosed inorganic paint. The panel has installed to the building external wall for five years, vertical surface is not soiling and not damaged but horizontal surface using for exterior structure is molding.
