DEVELOPMENT OF COST-EFFECTIVE SELF-CONSOLIDATING CONCRETE INCORPORATING FLY ASH, SLAG CEMENT, OR VISCOSITY-MODIFYING ADMIXTURES

The concept of self-consolidating concrete (SCC) as a building material has gained worldwide acceptance in recent years. The development of a cost-effective SCC with desirable fresh and hardened properties is important for such concrete to be used in structural construction in the future. SCC can be manufactured by incorporating either supplementary cementitious materials such as fly ash and slag cement, or viscosity-modifying agents (VMAs). Commercially available VMAs are expensive, making it important to explore new cost-effective VMAs to manufacture more economical SCC. This paper compares the performance of SCCs incorporating fly ash, slag cement, and VMAs based on fresh and mechanical properties. The feasibility of manufacturing such an SCC is assessed based on cost analysis. Results indicate that an economical SCC with the desired properties could be successfully developed by the incorporation of fly ash, slag cement, or VMA.
