Abstract

This paper presents the results of a testing program to examine the possibility of using plastic waste material to enhance the strength of wood chipping concrete. The plastic waste was cleaned and then cut to small pieces. On the other hand, the wood chipping was cleaned and passing from sieve of number 200 and was saturated in water for 24 hours. A total of 144 numbers of concrete specimens were cast at different replacement ratios of wood chipping with and without plastic waste of (0, 5, 10, and 15) % by weight of cement. All of the concrete mixtures were tested at room temperature. These tests include performing compression, split tension and flexural strength has per relevant British standard specifications. The results proved the arrest of the propagation of micro cracks by introducing plastic waste as coarse aggregate shapes on concrete mixture. The results of this study indicated an improvement in compressive, tensile and flexural strength of wood chipping concrete with(10, 9, 13)% comparing with normal concrete results of mechanical properties of (26.2, 2.3, and 0.44) at 7days age, and (39.3, 3.5, and 0.66) at 28 days age, respectively. This study insures that reusing plastic waste in wood chipping concrete gives a good approach to reduce the cost of materials and solve an environment problems of the solid waste materials.
