An increase in the concrete mixing temperature from 18 to 35 degree C (65 to 95 degree F) required an average increase of 4.7 kg/cubic m (8 lb/cubic yd) of cement to maintain the strength level. An increase in the delivery time from 20 to 90 min required an additional 13.6 kg/cubic m (23 lb/cubic yd) of cement…

What is the temperature of cement? - Quora

Feb 14, 2008· When operating under normal working temperatures, industry practices states that mortar use should remain in an ambient temperature range of 4.4 - 37.8° C. If the mix temperature drops to below 4.4°C within 24 hours for the mortar, and 24-48 hours for grout, the hydration of the cement will stop until the temperature returns to normal.
