The effects of binder content and silica sand content on the durability characterisitics of lightweight polymer concretes are examined. As a results, the flame lingering times using unsaturated polyester resin and non-combustible polyseter resin were 60~120 and 0~4 seconds respectively, and the combustin lengths were 9~11mm and 0~3mm, respectively. Thus it is believed that the lightweight polymer concrete was incombustible and the light weight polymer concrete in which non-combustible material was added was perfectly non-combustible. The percent of original mass of lightweight polymer concrete, according to the freezing-thawing experiment, was below 0.3%, which was much less than that of cement concrete.
