Abstract: This paper reports the results of a study undertaken to investigate the effects of non-evaporable water on the strength of foamed concrete incorporating classified and unclassified microwave incinerated rice husk ash (MIRHA). It investigates the relationship between non-evaporable water and compressive strength and presents mathematical models developed to describe this relationship. The compressive strength of the foamed concrete was found to be a function of non-evaporable water and age, with a multiplicative model providing the best fit for all ages up to 180 days. In addition, it was concluded that Powers' equation could effectively predict the compressive strength of foamed concrete mixtures containing MIRHA. Keywords: Foamed Concrete, Microwave Incinerated Rice Husk Ash (MIRHA), Non-evaporable water content
