超硫酸盐水泥早期强度影响因素及提高途径

摘要/Abstract

摘要： 超硫酸盐水泥是一种环境友好的材料,具有水化热低、抗蚀性能好、后期强度高等诸多优点,但存在早期强度低等缺陷。本文综述了超硫酸盐水泥早期强度影响因素及提高途径的研究进展,并对今后的研究方向进行了展望。矿渣活性、硫酸盐浓度,尤其是碱度,是影响该水泥早期强度的关键因素。通过选用活性较高的矿渣和溶解特性合适的石膏,使用具有控制碱度和促进矿渣溶解作用的添加剂等途径,可以有效提高该水泥早期强度。如何控制合适的碱度,进而控制水化产物的形成速率、形态和比例,是值得以后侧重研究的方向。

Abstract: As an environmentally friendly material, supersulfated cement has many advantages, such as low hydration heat, good corrosion resistance, and high strength in the later stage, but there are some deficiencies such as low strength in the early stage. The research progress of influencing factors and improving ways of early strength of supersulfated cement is summarized, and the future research direction has been prospected in this paper. Slag activity, alkalinity and sulfate concentration are the key factors affecting the early strength, especially alkalinity. There are some technical approaches to improve the early strength, such as selecting the slag with high activity and the gypsum with suitable dissolution characteristics, and using the additives with the function of controlling alkalinity and promoting the dissolution of slag. How to control the alkalinity, and then control the formation rate, morphology and proportion of hydration products, is worthy of being studied in the future.

Key words: supersulfated cement, early strength, slag activity, alkalinity, sulfate concentration
