Abstract:
The use of pozzolan, a minimum of cement, large size aggregate and low slump has long been standard practice for mass concrete. This paper deals with various techniques by which these leaner, harsher mixes can be incorporated into large structural concrete members or units. The concrete with a low cement factor is placed in areas of low stress and is bonded monolithically with the higher strength concrete. This not only results in a saving of cement, but also reduces the temperature rise of thick sections and thereby decreases the tendency for them to develop cracks oncooling.
