EXPERIMENTAL INVESTIGATION OF GREEN CONCRETE USING BOVINE FAECES ASH AND NON-DEGRADABLE PLASTIC WASTE MATERIALS

Abstract

Concrete is widely used in all kind of construction purpose and it is composed of cement, fine and coarse aggregates. To make the eco-friendly and economical construction, this research partially replace cement with cow dung ash to prepare the concrete. Non-biodegradable plastic trash is thus added to the concrete as an admixture in order to increase the tensile and compressive strength. Super plasticizers are also added to the concrete to increase its strength. In this study, the cement was partly substituted with cow dung ash in the proportions of 5%, 10%, 15%, 20% while non-degradable plastic waste materials was used as an admixture in the proportions of 1%, 1.5%, and 2% to create green concrete. To evaluate the performance and strength of the manufactured concrete samples (cube and cylinder), they are subjected to split tensile, flexural, and compressive strength tests after curing for 7, 14, and 28 days, respectively. For all the M20 grade of concrete mixes, addition of 15% of cow dung ash as a replacement of cement and 1.5% of non-degradable plastic waste material gives the maximum compression and tensile strength when comparing the control mix concrete. Hence this proves that partial replacement of cement with cow dung ash and addition of non-degradable plastic waste material as a admixture gives better results than normal M20 grade concrete which has better strength and eco-friendly in nature.
