基于石灰石粉-硅灰协同效应的低碳混凝土抗压力学性能研究
Investigation of Compressive Performance in Limestone Powder-Silica Fume Synergistic Low-carbon Concrete
摘要
Abstract
With environmental issues becoming increasingly prominent,the high carbon emissions in traditional concrete production have become an urgent problem to be solved.In this paper,limestone powder and silica fume are used as auxiliary cementitious materials to replace 40%of cement,forming low-carbon concrete(LCPC).To comprehensively evaluate its practical applicability,a systematic and in-depth study was conducted on the working performance,compressive mechanical properties and hydration products of LCPC by changing the ratio of limestone powder to silica fume.Compared with ordinary concrete(PC),LCPC with a cement content of only 60%demonstrates comparable workability and compressive mechanical properties.Particularly,its compressive strength and peak strain performance after 28 days of age are superior to those of PC.XRD analysis revealed that an increase in the amount of silica fume can significantly boost the quantity of hydration products in concrete,greatly reducing the cement content and carbon emissions without affecting mechanical properties,thus making a significant contribution to the development of sustainable building materials.关键词
