Waste Steel Wire Aggregates in Paver Block: A Green Approach

Abstract

Nowadays, the paving blocks in the market are costly. This study introduces a new type of paving block that is more affordable than conventional paving blocks. The new paving blocks are made from waste materials such as steel bearing balls, wires, lath scrap, and quarry dust, which makes them more environmentally friendly. In this study, the compressive strength eco-friendly paver block is compared to the conventional paving block. For manufacturing of paver block, bearing balls and wires have been used as coarse aggregate, while quarry dust has been used as fine aggregate. This paper presents a parametric experimental study on the production of paving blocks using waste steel wire aggregates in the form of steel wires cut to a length of 20-22 cm and rounded bearings of 6.35 mm. To investigate the increase in compressive strength, various percentages of waste steel wire aggregates are added to the concrete of paving blocks. The results of the tests revealed that integrating various percentages of wasted steel wire aggregates with paving blocks can increase impact strength by up to 50% when compared to standard paving blocks.
