早强减水剂有一定的早强、减水、增强作用，属自然养护型外加剂。本剂一般用于砖混结构建筑物所用的混凝土。掺本剂的混凝土在常温下成型5d后可以达到设计标号的75%以上。使用掺加本剂的混凝土浇筑圈梁、构造柱、阳台、雨蓬等构件强度增长较快，后期强度比不掺本剂的混凝土高。使用本剂既能缩短工期，又能保证工程质量。
本文介绍了早强减水剂的研究过程以及对工程实际的应用，并从机理上加以分析。
This article describes the development process of early-strength water-reducing agent and its application in construction. It also analysis of the principle.
前言： 研究了利用脱炭粉煤灰和高效早强减水剂的“双掺”技术，进行了公路混凝土路面的修复技术研究；
Using "double mixed" technology of decarburized fly ash and highly effect early strength water reducer, the renovation technologies of highway concrete pavement were studied.
添加剂包括减水剂，稳定剂，促凝剂，早强剂，防水剂等，可根据泡沫混凝土的用途和施工条件进行添加(也可不加)。
