Özet

Fine and coarse aggregates play a vital role in the fracture of concrete. There is however little quantitative information available in the literature on the effect of the volume fraction of the aggregates on the fracture properties of concrete. The main objective of this work is to gain a better understanding of this effect using appropriate experiment and a meso-mechanical approach. For this, several control mixes ranging from hardened cement paste (hcp) to normal concrete were prepared in which the aggregate grading, water to cement ratio, and the maximum particle size of aggregate were kept constant, but the volume fraction of aggregate was varied from 0.0 (hcp) to 0.60 in steps of 0.15.
