摘要
将凝灰岩石粉作为矿物掺合料掺入水泥基材料中,可实现减少水泥产量、降低CO_(2)等温室气体排放和利用工业固废。本文综述了凝灰岩石粉在水泥基材料中的作用机理,并系统总结了凝灰岩石粉掺入对水泥基材料的凝结时间、和易性、力学性能、耐久性能的影响规律,给出了凝灰岩石粉制备和使用建议,提出了凝灰岩石粉对水泥基材料性能影响研究中存在的不足,展望了凝灰岩石粉对水泥基材料性能影响未来需要注意的研究问题。
The incorporation of tuff powder into cement-based materials as mineral admixtures can reduce cement production and greenhouse gas emissions such as CO_(2),as well as utilize industrial solid waste.This review represented the mechanism of tuff powder in cement-based materials,and summarized the influence of tuff powder incorporation on the setting time,workability,mechanical properties and durability of cement-based materials.Some aspects for the preparation and use of tuff powder were given,and some problems for the effect of tuff powder on the properties of cement-based materials were proposed.In addition,some aspects for future studies on the properties of cement-based materials incorporating tuff powder were also discussed.
