Abstract

Results of an experimental study on the influence of density of aggregate on mechanical properties of high-strength concrete are presented. Using the same mixture proportions by volume, concretes with very dissimilar mechanical properties were obtained. A comparison of measured static modulus of elasticity to the calculated value obtained by using the equations from various building codes shows that the latter overestimate the modulus significantly. The influence of curing time on the drying shrinkage of concrete was also studied. The results confirm that the coarse aggregate type significantly influences the magnitude of shrinkage.
