Study of Foamed Concrete from Activated Ash/Slag Blended Cement


Article Preview

An ecotype of foamed concrete was prepared from activated fly ash/slag blended cement, a kind of low carbon cement, through physical foaming and hydrothermal curing process. The optimized material proportion and curing conditions were obtained with the aid of orthogonal array technique: activated fly ash/slag blended cement-600 kg and foaming agent-1kg for per cubic meter formed concrete, curing at 60°C for 6 hours. The density and compressive strength of the foamed concrete prepared in this method were 644kg/m3 and 4.5MP respectively, and with lower drying shrinkage and thermal conductivity, good freezing and thawing characteristics.
