| Abstract | ||||
| Waste recycling is a way to produce innovative low cost eco-friendly materials to solve environmental problems caused by different types of industrial by-product and polymeric wastes. Natural rubber loaded with different types of waste materials Calcium Hydroxide Ca(OH)2, Calcium Carbonate (CaCO3), Fly Ash (class F) and Waste rubber (WR) by mixing through open mill and then pressed in hot press to obtain low cost eco-friendly waterproofing membranes with desired properties. All samples pass the water penetration test up to 6 bars. The samples water absorption coefficients ranged from (0.1 to 0.3%) for all investigated samples. UV weathering and thermal aging tests were done to the samples while no changes on mechanical properties appeared before and after the tests. Dimensional stability test was done for all samples; a slight dimension change occurs. The mechanical and hardness measurements for all samples were done while good mechanical properties obtained. The price of square meter of 2 mm thickness for all samples was calculated in order to estimate its feasibility. A comparison of our samples with other waterproofing membranes from two famous Egyptian companies was done. Low cost and qualified waterproofing material can be obtained from recycling of some wastes. | ||||
