Improving the Thermal Insulation Properties of the Concrete Block with EVA Plastic Scrap
The aim of this research is to study about physical, mechanical, and thermal insulation properties of light weight concrete block products mixed with ethylene vinyl acetate plastic scrap (EVA) from shoe factories. The ratio of cement: aggregates (quarry dust + EVA): water is 1:4.5:1.66 by weight. EVA to cement ratios (E/C) are fixed at 0.00, 0.33, 0.42, 0.50 and 0.58. The concrete block samples are cast for testing the necessary properties followed the TIS standard 58-2533. From the experiment, EVA plastic with the appropriate size and quantity are well adhesive with cement as well as quarry dust mixture. The least density of light weight concrete block mixed with waste of ethylene vinyl acetate plastic products is 640 kg/cu.m. The appropriate mixtures of light weight concrete block mixed with EVA plastic scrap can reach the required values from the standard of TIS 58-2533 and can be used as a thermal insulation wall.
