Delay in setting of concrete beyond 24 hours:Delay in setting of concrete is mainly due to excess dosage of set retarding admixture used to retain pumpable slump for longer durations. These admixtures are used to prolong the plasticity of concrete.Useful to counter the effects of high temperature, eliminate cold joints, and reduce cracking

Use of Water Reducers, Retarders, and Superplasticizer

ASTM C494 Type F and Type G, High Range Water Reducer (HRWR) and retarding admixtures are used to reduce the amount of water by 12% to 30% while maintaining a certain level of consistency and workability (typically from 75 mm to 200 mm) and to increase workability for reduction in w/cm ratio. The use of superplasticizers may produce high strength concrete (compressive strength up to 22,000 psi).
