Preperties of Foamed Concrete using Fly Ash for On-Dol

온돌 채움용 플라이애쉬 경량기포콘크리트의 품질 특성

Foamed concrete is applied ad filling, material of On-dol, bur it has much trouble in controlling the quality because of not establishing the detailed related criteria and recommendation for the construction and quality control practice. Therefore, this study will investigate the as-placed density and air content of formed slurry before hardening and its physical characteristics after hardening, analyzed the relation of each characteristic, and finally provide the proper method for the quality control foamed concrete.
