混凝土早强性能研究进展和展望

Research Progress and Prospect of Early Strength of Concrete

混凝土材料是工程建设中最常用的一种建筑材料,由于其具有较强的塑形能力、较高的结构强度以及超低的经济造价等优势,在各种工程建筑项目上得以广泛应用。混凝土早强剂是一种无氯盐碱水复合型材料,可以有效缩短混凝土凝结时间、提高混凝土早期强度。得益于早强剂显著的商业价值,国内外企业和学者对混凝土早强性能研究持续深入,也取得了不少成果。笔者总结分析了混凝土早强性能研究进展,并对未来早强性能研究方向进行展望,以供参考。

concrete material is the most commonly used building material in engineering construction.Be⁃cause of its strong shaping ability,high structural strength and ultra-low economic cost,it is widely used in various engineering construction projects.Concrete early strength agent is a chloride free saline alkali water composite material,which can effectively shorten the setting time of concrete and improve the early strength of concrete.Thanks to the remarkable commercial value of early strength agent,domestic and foreign enterprises and scholars have continued to conduct in-depth research on the early strength per⁃formance of concrete and achieved great results.The author summarizes and analyzes the research prog⁃ress of early strength performance of concrete,and looks forward to the research direction of early strength performance in the future for reference.
