Optimization of Industrial Wastes as Partial Replacement in Production of Concrete

Abstract

In the present world the production of cement is highly costly and significantly affects the environment. The CO2 emissions has increased manifold over the last decade or so leading to global warming. Thus, it is the need of the how to control the usage of cement so that its production can be reduced for optimal usage. The present study has been done to find the optimal usage of industrial by products fly ash of class F, silica fume and rice husk ash to be used as a substitutes to cement. The present study has been done to study the effects of different input parameters like mix by - product percentage used as a binder, type of concrete, mix percentage of coarse aggregate of two type 10mm and 20mm and curing days on output response namely compressive strength of concrete cube of size (150mm×150mm×150mm). The effect of various parameters on output responses have been analysed using ANOVA and followed by the optimization of process parameters. Main effects have been plotted to determine the optimal design for each output parameter.
