Question

The total heat evolved in hydration of cement decreases with an increase in the water/cement ratio

Answer 1

When cement comes in contact with water, there is an instantaneous heat burst. This is the point where a lot of heat is produced. However, various experiments that have been conducted indicate that the variance of water to cement ratio leads to little or even no increment in the amount of heat produced. The rate of heat production does not hit the zero mark or become negative with increase in water/cement ratio indicating that the production of heat slows down but does not stop
