1. Moisten subgrades and forms to prevent absorption.
2. Dampen dry aggregates that are absorptive.
3. Reduce the temperature of the concrete by
a. Precooling aggregate with water.
b. Cooling the cement.
c. Using chipped ice to cool mixing water.
d. Shading aggregates, water tanks, and lines.
1. Avoid overmixing.
2. Place concrete early in the morning or late afternoon.
3. Construct temporary walls to reduce wind velocity.
4. Provide sunshades for concrete.
5. Reduce time between placing and start of curing by working efficiently during construction.
6. Use evaporation retardant (usually polymers).
7. Use fog sprays to keep the humidity high and the air temperature low.
