The Experimental Study on the Mixing Properties Substitute for Fly-Ash by Lightweight Concrete Products

경량 콘크리트 제품에 플라이애쉬를 치환한 배합특성에 관한 실험적 연구

This study was to operate a fitting production specific of concrete product for proper mixing discovery. Testing method was to operate slump, air content, compressive strength test. The standard was water-cement ratio 50% and weight substitution 0%, 10%, 20% by Fly-ash and using Silica-fume and HPMC(Hydroxy propyl methyl cellulos) by additive. The result of this study showed when add Fly-ash to Silica-Fume is better than HPMC.
