Abstract

The aim of this research was to evaluate the physical-mechanical parameters of paving stones obtained on the basis of the mixture of linear low-density polyethylene (LLDPE) and palm kernel shell ash (PKSA) waste. The ratio of LLDPE to PKSA waste (% weight) was varied in five treatments: A0 (100:0), A1 (97.5:2.5), A2 (95:5), A3 (92.5:7.5), A4 (90:10) and A5 (87.5:12.5). The physical appearance, thickness, compressive strength, water absorption, and morphological characteristics of the paving blocks were observed. The blocks were observed at ambient temperature, exposed to sunlight, and placed on the ground surface on day 0 and day 365. The results showed that addition of PKSA waste decreased the compressive strength but increased the water absorption capacity without a significant effect on the thickness of the paving blocks. Observation after 365 days showed insignificant decreases of compressive strength and thickness, whereas the water absorption capacity increased slightly. Small cracks and more voids in the surface, and more brittleness were observed. To summarize, composites of LLDPE and PSKA as filler have physical-mechanical properties that can be used for road pavement blocks.

线性低密度聚乙烯与棕榈仁壳灰混合料对路面砌块物理、力学及降解性能的影响

本研究的目的是评估基于线性低密度聚乙烯（LLDPE）和棕榈仁壳灰（PKSA）废物的混合物获得的铺路石的物理力学参数。在A0（100:0）、A1（97.5:2.5）、A2（95:5）、A3（92.5:7.5）、A4（90:10）和A5（87.5:12.5）五个处理中，LLDPE与PKSA废料的比例（%重量）不同。观察了铺路砖的物理外观、厚度、抗压强度、吸水性和形态特征。在环境温度下观察块，暴露在阳光下，并在第0天和第365天放置在地面上。结果表明，添加PKSA废料降低了抗压强度，但增加了吸水能力，而对铺路砖的厚度没有显著影响。365天后的观察显示，抗压强度和厚度显著降低，而吸水能力略有增加。观察到表面有小裂纹和更多的空隙，以及更多的脆性。总之，LLDPE和PSKA作为填料的复合材料具有可用于路面砌块的物理力学性能。
