Original Abstract

Next to compressive strength, the modulus of elasticity is an important property for the design and behaviour of concrete structures sensitive to deformation (pre-stressed elements, slender structures, etc.). The concrete modulus of elasticity in compression is a material property, which can, due to various influences, reach very different values within one strength class of concrete. For this reason, it is necessary to know the factors that have the greatest influence on the modulus of elasticity and compressive strength at the same time. One of those factors is ambient temperature, which influences both these properties in the early stage of setting and hardening. If the low ambient temperature causes the concrete to not attain a sufficient value of modulus of elasticity and compressive strength, significantly more severe deformations may occur together with serious problems e.g. during early pre-stressing of the concrete element (as early as the age of 24 hours).
