Abstract


The heat of hydration developed in reactions of mortars and concretes can be sensibly reduced using pozzolanic materials. However, the decrease of the heat of hydration is not directly proportional to the amount of cement substituted, because of the heat released in the pozzolanic reaction. With materials of high pozzolanic activity as silica fume or opaline rocks very, the heat is even increased.
