绿色低成本超高性能混凝土性能与微观机理评价分析
Evaluation and analysis of the performance and microscopic mechanism of green low-cost ultra-high performance concrete
摘要
Abstract
To address the challenges associated with ultra-high performance concrete(UHPC),such as its low water-to-cement ratio,high production costs,and substantial cement consumption,this study developed an eco-friendly and cost-effective UHPC variant.This was achieved by incorporating industrial solid wastes and natural pozzolanic materials,specifically limestone powder,slag,and pumice powder,as supplementary cementitious materials.UHPC performance test,BBD response surface test,PCAS porosity analysis system and SEM scanning electron microscopy were used to explore the effects of various admixtures on its basic physical properties and microstructure.The results show that substituting cement with limestone powder,slag,and pumice powder not only enhances the mechanical strength and durability of UHPC but also refines its microstructure.Moreover,this substitution strategy significantly reduces both the economic and environmental costs of UHPC production while maintaining its superior performance.The outcomes of this study offer valuable insights for the formulation of sustainable and economically viable UHPC,contributing to the advancement of green construction materials.关键词
