Abstract This article reviews proposed technical approaches for the manufacture and use of alternatives to Portland Cement Clinker as the main reactive binder component for ordinary concrete construction in non-specialty applications, while giving lower net global CO2 emissions in use. A critical analysis, taking into account a wide range of technical considerations, suggests that, with the exception of alkali-activated systems, (treated in a separate paper in this issue,) there are only four classes of alternative clinker system that deserve serious attention with respect to global reductions in concrete-related CO2 emissions: (A) Reactive Belite-rich Portland cement (RBPC) clinkers (B) Belite-Ye'elimite-Ferrite (BYF) clinkers (C) Carbonatable Calcium Silicate clinkers (CCSC) (D) Magnesium Oxides derived from Magnesium Silicates (MOMS) A and B are “hydraulic” clinkers, (i.e. clinkers which harden by reaction with water,) C is a “carbonatable” clinker, (i.e. one which hardens by reaction with CO2 gas) and D can fall into both categories.

替代水泥熟料

摘要 本文回顾了制造和使用波特兰水泥熟料替代品作为非专业应用中普通混凝土结构的主要反应性粘合剂组分的技术方法，同时降低了使用中的全球二氧化碳净排放量。考虑到广泛的技术考虑因素的批判性分析表明，除了碱活化系统（在本期的另一篇论文中进行了处理），只有四类替代熟料系统值得认真关注关于混凝土相关二氧化碳排放量的全球减少：(A) 富含反应性 Belite 的波特兰水泥 (RBPC) 熟料 (B) Belite-Ye'
