oa Civil Engineering = Siviele Ingenieurswese - Prediction of elastic modulus for design of concrete structures

 

Abstract

The prediction of the elastic modulus of concrete for design is complicated by the variety of factors affecting this parameter. The influences of aggregate stiffness and concrete strength are incorporated in a new design approach which is being included in the new BS 0000 (originally CP 110). The application of this approach to South Alrican conditions is discussed with specific relerence to local aggregates and cements. Aggregates have been grouped according to their elastic properties so that designers can make beller estimates of concrete modulus than might have previously been possible. The ideal approach to elastic modulus prediction by means of the concept of two-phase models is also introduced.
