An Experimental Investigation on Mechanical Properties of High Strength Performance Concrete using GGBS and Alccofine

The necessity of high performance concrete is increasing because of the increasing demand of the construction materials in the construction industry. Efforts for improving the performance of concrete over the past few years suggest that cement replacement materials along with Mineral & chemical admixtures can improve the strength and durability characteristics of concrete. This project is an attempt to study the behaviour of Alccofine 1203 (5%, 6%, 7%, 8% and 10% replacement by weight of cement) along with Fly Ash (15%) and GGBS (15%) replacement on fresh & hard property of concrete. As well as optimizing the percentage dosage of chemical admixture to achieve required retention period (up to 3hrs) and workability (Slump and Flow) to increase the productivity of concrete design. This paper also studies the effectiveness of applying value engineering to actual concrete mixtures. The application of value engineering to such concrete mixtures results in increase in performance, optimizing the mix by adding appropriate dosage of admixtures so as to work in different situation and increase its value, increase in durability of structure in which concrete will be used, reduction in cost of concrete and overall cost of construction projects, increasing the market share and competitiveness of concrete producers. This research shows that applying the methodology of value engineering to readymixed concrete is an effective way to save around 7.5-8.5 % of the total cost of concrete mixtures supplied to construction projects..
