Some Mechanical Properties of Concrete Incorporating Plastic Wastes and Marble Dust Wastes

This research investigates incorporating locally produced wastes which are marble dust waste (MDW) and shredded fibrous plastic wastes (SFPW) on the physical and mechanical properties of normal strength concrete. For this particular reason, testing program that involves 20 different mixtures of concrete is developed. MDW is utilized as a cement’s replacement in concrete with the percentages of 0, 5, 10, 15, and 20. On the other hand, SFPW is used as an additive by means of the cement volumes with a proportion of 0, 2, 3 and 5%. The influence of these mixtures on the fresh concrete slump, compressive and splitting tensile strength, and flexural strength were studied. Results indicated that physical characteristics such as workability was affected slightly. On the other hand, the mechanical response does vary where it outperforms the control mixture at some replacement levels and underperform at high replacement levels. It is concluded that the optimal replacement levels of the MDW and SFPW is 5% and 2%, respectively.
