Abstract

The compressive strength and density of aerated concrete are largely influenced by the composition and method of airing. Conventionally, strength is related to density alone, with little attention paid to the composition. This paper discusses the development of prediction relations for compressive strength and density of aerated concrete through statistically designed experiments. A discussion on the behavior is made through the analysis of response surfaces. Optimisation of mixture proportions has also been carried out. The relative influence of autoclaving, as compared with moist curing on compressive strength of aerated concrete, is brought out through the autoclaving efficiency factor.
