can anyone explain the crack pattern of cement concrete cube ???
Higher coarse aggregate content, the use of very fine and high-angularity sand, poor aggregate gradation, incompatible mineral and chemical admixtures, inadequate curing, delayed finishing, high rate of evaporation from concrete surface, and sudden temperature drop are the major causesof plastic shrinkage cracking.

Thanks for the reply sir, but I am talking about crack pattern during compressive strength testing of cement concrete cube-like horizontal cracks, vertical cracks or failure in shear.
