Experimental Research of Shrinkage in Thick Concrete Elements

Article Preview

Abstract:

At the construction of complex concrete structures of the laser centre, the client required verification of casting procedures on large scale models. Models of the thick floor slab and of the thick wall were built in the scale 1:1, where the temperatures induced by heat of hydration and shrinkage strains were measured. The results of the experiments showed that the measured strains were larger than those expected on the basis of prediction according to European codes. Experimental results were compared with the results of numerical analysis.
