Engineering Properties of Cement Mortars Made with Television Plastic Shell Waste (TPSW)

This study explores a sustainable method for recycling television plastic shell waste (TPSW) by using it as a partial replacement for sand in cement mortar production. By evaluating water-cement ratios (0.4, 0.5, 0.6) and TPSW levels (0%, 5%, 10%, 15%), the research assesses key properties such as slump, compressive strength, and durability. Results show that TPSW absorbs less water than natural sand, increasing the number of pores and slightly reducing strength. However, a 5% substitution led to minimal performance loss after 91 days, while improving sulfate resistance and resistivity. Overall, incorporating 5% TPSW reduces environmental impact and carbon emissions, offering a sustainable solution for cement production.
