Abstract

This study investigates the possibility of using waste plastic as one of the components of expired lead-acid batteries to produce lightweight concrete. Different percentages of lead-acid battery plastic were used in the production of lightweight concrete. The replacements were (70, 80 and 100%) by volume of the fine and coarse aggregate. Results demonstrated that a reduction of approximately 23.6% to 35% in the wet density was observed when replacement of 70% to 100% of the natural aggregate by lead-acid battery plastic. Also, the compressive strength decreased slightly with the increase in plastic content at different curing ages of 7, 28, 60, 90, 120 days. The lowest value of compressive strength was (20.7 MPa) for (waste plastic =100%) at (120) days test age. The results also revealed that the thermal conductivity decreased by the addition of waste plastic compared to plain concrete and this property is decreased due to an increase in waste proportion.

The replacement of 70% to 100% of the natural aggregate by lead-acid battery plastic (LABP) caused a reduction of approximately 23.6% to 35% which is in agreement with the finding of many previous studies such as Marzouk, et al, 2007, Akçaözoğlu, et al, 2013, Fraternali, et al, 2011 and Yesilata, et al, 2009
As shown in this figure, increasing level of LABP replacement resulted in the reduction of compressive strength at all curing ages but all of the compressive strength values were greater than the minimum compressive strength required for lightweight structural concrete which is 17.24 MPa

Summary

Introduction

Number 12 Volume 24 December 2018 Journal of EngineeringDue to the socio-economic characteristics, a variety of consumption and differences in waste management programs are different in each country. Ahmed, 2013, used the recycled plastics as a partial replacement of coarse aggregate in concrete and concluded that the use of plastic solid waste in concrete results in the formation of lightweight concrete.
