Fresh concrete is placed against absorbent forms in hot weather without pre-wetting or curing planning. What is the concern?
Correct Answer
C) Moisture loss.
Absorbent forms and hot conditions can accelerate moisture loss. Prepare forms appropriately and implement the planned curing and weather protection; do not add uncontrolled water to the mixture as a substitute. NRMCA CIP 12 discusses wetting forms and controlling hot-weather evaporation. Source: https://www.nrmca.org/wp-content/uploads/2021/01/12pr.pdf
