"Demonstration of Utilising High Volume Fly Ash Based Concrete For Structural Application" 
by Bengal Engineering & Science University, Howrah

Scope

The project aims to determine the optimum fly ash content (40 to 60%) in concretes (made with OPC and PPC) designed to meet the requirements of concrete grades M25, M40 and M60 by using Indian fly ashes. The mechanical properties and some durability characteristics of these concretes will also be determined.

Parameters

• Task 1: Procurement of materials - The materials to be used in the study will be procured.
• Task 2: Characterisation of cementing materials - The physical properties and chemical composition of cements and fly ashes will be determined.
• Task 3: Optimisation of fly ash content in concrete - A total of 33 types of concrete mixtures will be made. The optimum fly ash content will be determined based on 3, 7 and 28 days compressive strength and the cost of the concrete mixture.
• Task 4: Performance of high-volume fly ash concretes - based on Task 3, optimum fly ash content will be determined for each grade of concrete i.e. M25, M40 and M60 made with both OPC and PPC. These six types of concretes with optimum fly ash content plus three control concretes made with each OPC and PPC will be made.
