Abstract
There have been several investigations in the past on the influence of mixture
composition on the properties of foam concrete. Conventionally strength is
related to density alone and few model have been developed relating strength
with density, porosity, gel–spaceratio, etc. Very little work has been reported in
the literature in predicting the properties of foam concrete from the knowledge
of itsmixture proportions. This paper discusses the development of empirical
models for compressive strength and density of foam concretethrough
statistically designed experiments. The response surface plots helps in visually
analysing the influence of factors on the responses.The relative influence of fly
ash replacement on strength and density of foam concrete is studied by
comparing it with mixes without fly ash and brought out that replacement of
fine aggregate with fly ash will help in increase in the strength of foam concrete
at lower densitiesallowing high strength to density ratio. Confirmatory tests
have shown that the relation developed by statistical treatment of experimental
results can act as a guideline in the mixture proportion of foam concrete
