PREDICTION RELATIONS FOR COMPRESSIVE STRENGTH OF AERATED CONCRETE

The compressive strength and density of aerated concrete are largely influenced by the composition and method of curing. 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. Optimization 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.
