Abstract:
To dimension the structural systems of reinforced or prestressed concrete, it is necessary to know at least the elastic modulus and the compressive strength of the concrete. This is because several factors directly influence these two properties, from the dosage to the procedure adopted for curing the concrete. Therefore, this study aims to present the influence of two different types of curing (humid and thermal steam) over the elastic modulus of the concrete. The results demonstrate that a significant reduction occurs on the modulus when the concrete is submitted to thermal steam curing. Additionally, the increase in the volume of the paste in the mixture reduces the stiffness of the compound.
