Loss of slump and workablity and higher water requirement, particularly in warm weather, often impair quality of concrete. Investigation of corrective agents included development of a penetration resistance test to measure rate and progress of hardening, which is described. The effect of various factors such as temperature, character and amount of cement, and type and amount of retarding agent on rate of hardening, early strength, water requirement, and durability, are reported.
