摘要
基于国内外的研究成果,将早强型混凝土的制备方法分为掺早强剂、使用特种水泥和掺高分子聚合物三种。分别归纳总结了这三种方法对混凝土早强性能的影响,并简要分析了各制备方法所存在的问题。此外,介绍了目前提高超高性能混凝土(UHPC)早强性能的方法,并对其未来的研究方向进行了展望。
Based on the research results at home and abroad,the preparation methods of early-strength concrete are divided into three types:early strength admixtures,special cement-based materials and high-molecular polymer.The effects of these three methods on the early strength of concrete are summarized.The problems of each preparation method are briefly analyzed.In addition,the current method of ultra-high performance concrete(UHPC)to improve the early strength performance is introduced,and its future research directions are prospected.
