Thermal Properties of Lead-Acid Battery Plastic Lightweight Concrete

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.

Evaluation of Some Beneficial Environmental Impacts and Enhanced Thermal Properties Resulting from Waste Plastic Integration into Concrete

“…Moreover, experimental findings obtained from some scholars demonstrated that concrete might be engaged in multiple practical construction settings thanks to the addition of waste plastic and amended thermal insulation [82][83][84][85][86][87][88].…”
