  • The purpose of this study was to analyze the compression strength research by aerated concrete as mixing ratio This Study used foaming-agent and produced aerated concrete by pre-foam way that is used in construction site. An experiment changes unit cement amount, w/c and the glass fiber mixing rate and 'measured capacity change, unit capacity weight and compressive strength. The results obtained from experimental study are as following; Research to reduce unit capacity weight in condition more than unit cement amount 500kgf is considered should be gone side by side. The highest compressive strength result appeared in aerated concrete that cement amount 600kgf and w/c ratio $45\%$, $50\%$. compressive strength was increased maximum $34%$ when glass fiber $0.7\%$ addition cause by coherence enlargement to enlargement of cement paste and glass fiber addition per unit volume

  • Pre-foaming, one of the manufacturing way of foamed concrete, is influenced by foaming agent. When the foaming agent diluted with water, surface tension and viscosity are varied. Therefore, this study is reviewing the surface tension, viscosity and unit weight of foam by experimental factor such as foaming agent types(AES, AOS, VS FP) and foam agent dilution concentration (1, 3, 5%) and temperature of materials (5, 10, 20℃). As an expeimental result, the surface tension and viscosity slightly increased with increasing concentrations. Meanwhile, when increasing temperature, the viscosity has decreased. FP produce relatively stable foams only in case 3% or more, which produce unstable foams containing large amount of water content by decreasing only insignificant surface tension when diluted at concentration of 1%.
