Solidification of waste rubber and fly ash using modified sulfur polymer

Abstract

This study utilized several surplus industrial wastes in making non-cementitious construction materials. The main objective of this study is to develop modified sulfur composites that possess superior sustainability to Portland cement concrete (PCC). Dicyclopentadiene (DCPD) modified sulfur was used as a binder with thermoplastic property. The rubber powder and micro-filler (fly ash and cement) were used as the additives in this study. Fundamental physical properties of modified sulphur composites were investigated. Several microstructural analyses (e.g., scanning electron microscopy, X-ray diffraction) were conducted
