Investigations on the modulus of elasticity of young RCC

The paper deals with the investigations on the modulus of elasticity (Young’s Modulus) and the stress–strain-behavior of one Roller Compacted Concrete (RCC) mixture from the age of 6 hours to 365 days. Focus is on the characteristic of very young RCC as its behavior in respect of stress–strain-relations differs considerably from that of aged RCC. The results of the investigations are processed with regard to the accessibility of the data for numerical temperature stress analysis, for which a detailed knowledge of the evolution of stiffness has to be gained especially in the initial phases of the hydration process.
