Use of Water Reducers, Retarders, and Superplasticizer
WRA has been used primarily in hot weather concrete placing, pumping, and tremie. Careful concrete placement is required, as the initial setting time of concrete will take place an hour earlier. It is also shown that the use of WRA will give a higher initial concrete compressive strength (up to 28 days) by 10% compared to the control mixture.
