Production of High Strength and Durable Concrete Using Industrial By-Products

Abstract

In the today’s construction scenario there is a acute shortage of fine aggregate (sand) as well as cement production is highly energy intensive, costly and affects the environment. The present study has been done to find the optimal usage of industrial by-products (Blast furnace slag, Ladle furnace slag, Fly-ash, Electric arc furnace slag, Glass powder and Steel powder/Scrap) as substitutes to cement and aggregates. The present work aimed to study the effect of different input parameters, namely water to cement ratio, by-product percentage used as a binder, by-product percentage used as a fine-aggregate, type of by-product used as a binder, type of by-product used as a fine-aggregate and curing time on output responses, namely compressive strength, splitting tensile strength and water penetration depth. The effect of various input parameters on output responses have been analyzed using Analysis of Variance (ANOVA) and followed by optimization of the process parameters. Main effect plot has been used to determine the optimal design for each output parameters.
