Abstract:
The elastic modulus of concrete is an important parameter in reinforced concrete design and analysis. With the in- creased use of lightweight aggregates for structural con- crete a better understanding of the relationship between weight, strength, and the elastic modulus is needed. In this study the static modulus for a large variety of aggregates and concrete strengths was analyzed and an empiri- cal formula was derived which is applicable to both Ii ht-weight and normal weight structural concretes. The formula is in excellent agreement with recognized empirical formulas for normal weight concrete.
