Design of a strength model for foamed lightweight soil

Abstract Foamed lightweight soil has been widely used in civil engineering, and the model for foam concrete employed to predict its strength. However, various previous strength models of are generally based on assumption complete hydration, which is not case foamed soil. For example, Nambiar’s (reference), a simple model, sets ratio hydrated water cement by weight as an empirical constant, actually related water-cement before completion hydration To address this issue, improved tailor-made was proposed establish relationship between ratio. The original were compared with actual data, shows that more effective
