Making of Paver Blocks With the Help of Demolished Building Waste

Abstract

Abstract: Now a days threr is a significant world-wide interest to solve the environmental problems caused by industrial waste such as waste generated from demolished structure. For making sustainable devolopment by using these waste materials for manufacturing of paver blocks. Many manufatrures were making paver blocks by using cement and various ingredients. This technology has been introduced in Indian construction activities, a decade ago, for specific construction of various floorings namely footpaths, parking areas etc. but now being adopted extensively in different uses where the conventional construction of pavement using the demolished building waste can be made to make green concrete paver blocks. Due to rapid urbanization there is a great increase in building construction, so is the demolition. There is no proper disposal of the demolition waste. About 530 million tons of C&D waste is generated annually. But only a few amounts of demolished concrete is recycled or reused. In this study, experimental investigations have been carried out to evaluate the effect of complete replacement of fine aggregate by demolition waste on compressive strength, which is compared with a conventional block. The concrete blocks were made in M20 mix. Further, the test was carried out in concrete paver block, in M40 mix design. The concrete paver blocks show 91% strength attainment at 28 days and it is only a marginal deterioration in the compressive strength. Therefore, the concrete blocks made with demolition waste can be used in low load bearing pavements. Keywords: Demolishen, Paver blocks
