Description The present invention relates to a method of preparation of paver block utilizing waste polythene bags. The object of the proposed invention is to utilize sustainable waste material and analogously minimizing the consumption of fine aggregate by replacing it with waste polythene bags in shredded form. The composition for preparation of sustainable conplas paver blocks comprises of cement (17.15%, 416.67 kg), fine aggregate (26.79%, 650.95kg), coarse aggregate (48.15%, 1170kg), waste polythene bags (1.71%, 41.55kg) and water (6.19%, 150.5kg) for production of one cubic meter concrete. Conplas paver blocks have unique feature of high impact resistance and energy absorption capacity. Following invention is described in detail with the help of Figure 1 of sheet 1 showing schematic presentation with dimensions of the sustainable conplas paver block.

Description The present invention relates to a method of preparation of paver block utilizing rubber waste. The object of the proposed invention is to utilize waste tyre material and replacing the fine aggregate by waste tyre rubber ash (in powder form) and rubber fibers (in shredded form). The composition for preparation of sustainable rubcrete paver blocks comprises of cement (15.83%, 365 kg), fine aggregate (26.50%, 611 kg), coarse aggregate (48.79%, 1125 kg), waste rubber ash (1.69%, 39 kg), waste rubber fibers (1.34%, 31 kg), water (5.55%, 128 kg) and super plasticizer (0.30%, 7 kg) for production of one cubic meter concrete. Proposed paver blocks have unique feature of high energy absorption capacity, better abrasion resistance, and less water absorption. Following invention is described in detail with the help of Figure 1 of sheet 1 showing schematic presentation with dimensions of the proposed sustainable paver block.
