生态超高性能混凝土制备与性能研究
Study on Preparation and Properties of Ecological Ultra-High Performance Concrete
摘要
Abstract
In this paper,eco-friendly ultra-high performance concrete(UHPC)was prepared by replacing mineral powder and river sand with soda residue(alkali slag)and sea sand at various substitution ratios,respectively.The results show that the flexural strength of UHPC decreases with the increase of soda residue substitution ratio.The maximum compressive strength of 143.2 MPa is obtained at 20%soda residue substitution,which is higher than that of the control group(131.6 MPa).At 20%sea sand substitution,the flexural strength and compressive strength of specimens after high-temperature water curing are 12.92 MPa and 142.6 MPa,respectively.关键词
