Effect of High Temperatures on Concrete , The temperature that concrete has reached often can be determined by observing color changes in the aggregate For example, limestone aggregates turn pink when they reach about 570º F, which can result in substantial loss of compressive strength
temperature of the cement leaving the mill will be dependant on the temperature of the materials (especially the clinker) fed to the mill and to features of the mill and the grinding process
concrete, which is significantly lower than the slump of concrete made with room temperature materials Also, it was observed that liquid nitrogen can be used to extend setting time of concrete,
