Due to the fast proliferation of electrical and electronic equipment (PCs, TVs, and cell phones, among others), the disposal of plastic waste, such as acrylonitrile butadiene styrene derived from discarded electrical and electronic equipment (e-Waste), is becoming a big issue. This paper addresses this subject by utilising granulated ABS as an aggregate replacement material in concrete. The compressive strength and abrasion resistance of granulated ABS derived from electronic waste in concrete were evaluated in different replacement intervals (0 %, 5 %, 10 %, 25 %, 50 %, 75 %, and 100 %). The current investigation included microstructural and morphological characterisation utilising scanning electron microscopy and X-ray diffraction pattern analysis. It was found that increasing the replacements of granulated ABS for the natural aggregate reduced concrete's workability, strength, and abrasion resistance. To compensate for the loss in strength and abrasion wear resistance, mixes were subjected to a precarbonation curing regime to densify the microstructure of the cementitious paste.

使用源自废弃电气和电子设备的 ABS 塑料制成的预碳化和水固化混凝土的耐磨性

由于电气和电子设备（个人电脑、电视和手机等）的快速普及，塑料废物的处理，例如从废弃电气和电子设备（电子废物）中提取的丙烯腈丁二烯苯乙烯，正在成为一项重要的任务。大事件。本文通过利用粒状 ABS 作为混凝土中的骨料替代材料来解决这个问题。在不同的更换间隔（0%、5%、10%、25%、50%、75% 和 100%）下评估混凝土中源自电子废物的粒状 ABS 的抗压强度和耐磨性。目前的研究包括利用扫描电子显微镜和 X 射线衍射图分析进行微观结构和形态表征。研究发现，增加粒状 ABS 替代天然骨料会降低混凝土的和易性、强度和耐磨性。为了补偿强度和耐磨性的损失，对混合物进行预碳化固化，以致密水泥浆体的微观结构。
