Title: Prediction Relations for Compressive Strength of Altered
Author(s): N. Narayanan and K. Ramamurthy
Publication: Materials Journal
Appears on pages(s): 367-373
Keywords: autoclaving; cellular concretes; compressive strength; opti-mization.
Abstract: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 rela-tions 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 mix-ture 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 fac-tor.
