PROPORTIONING OF FLY ASH CEMENT CONCRETE MIXES

Fly ash accumulates around the world at the rate of several million tons per day. The slow rate of strength gain is the main problem with using fly ash in concrete mixes. Existing methods of proportioning fly-ash concrete are complex and do not consider directly the properties of the constituent materials. The Generalized Approach for Mix Proportioning developed at the Indian Institute of Science, Bangalore, provides a foundation for the development of a new method. The proposed method takes into account the characteristics of cement, fly ash, and aggregates. The proportions of fly-ash concrete mixes were arrived at using the Generalized Approach for Mix Proportioning. The proposed method was applied to and found applicable for fly-ash concretes using fly ashes from two different sources.
