Abstract
The use of industrial by-products and wastes in construction industry solves two fold problem of the waste by-product disposal and development of sustainable building material. The disposal of PET bottles and steel chip powder or SCP (major by-product of steel and fabrication units) is a major problem as they are non biodegradable in nature. So these by- products (PET and SCP) pose an environmental issue and its usage in construction industry can be a major achievement. This paper explores the possibility of using shredded PET bottles and steel chip powder (SCP) in mortar. The effect of adding PET and SCP in the compressive strength of the mortar were experimental investigated the mortar proportion of 1:3 with replacement percentage of 2, 4, 6 and 8 with keeping water-cement ratio constant. The strengths of specimen were recorded for 28 days and 7 days and results showed that the strength decreased drastically when percentage replacement was increased and it was concluded that 6 percentage replacements is optimum replacement. Also it was observed that workability decreased as percentage replacement increased.
