Elastic moduli of cement pastes and concretes having water: cement ratios ranging from 0.25 to 0.775 and aggregate contents of up to 73 per cent by volume were measured at ages between 3 and 1,280 days. Volume proportions of unhydrated cement, hydrated cement and voids were determined from evaporable and non-evaporable water contents. It was found that the elastic modulus of bulk hydrate could be expressed as a power function of the volume concentration of hydrate in the space available to accommodate it. Substitution of this parameter into maxwell parallel models gave values for the elastic modulus of cement paste and for concrete which were in reasonable agreement with experiment.
