With water/cement ratio above 0.5, the influence of water/cement ratio falls off and at 0.65 water/cement no difference in strength is observed. The properties of coarse aggregate have been found to have little effect on direct and splitting tensile strength, but flexural strength is found greater with the use of crushed and angular crushed rock aggregate than the rounded gravel.
