Experimental research was done in a laboratory to duplicate field abuse of 4000 psi concrete on one job. It was desired to find the amount of strength loss due to high slump, extended mixing with slump kept at the high figure, high summer temperature, and partial abuse of cylinders. It is interesting that job strengths were almost duplicated using two different brands of cement.
