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.

1/6/1986 · Concrete was batched to produce a 2- to 4-inch slump and the low-slump-loss superplasticizer was added at the plant to bring the slump up to about 8 inches for placing. The combination of good sand grading, adequate cement content, high slump, and extended slump life helped to ensure pumpable concrete, even at high placing temperatures.
