摘要: 花岗岩加工过程中产生大量的废泥浆,废泥浆的随意倾倒将对环境和人类健康造成危害。近年来,一些研究者利用花岗岩废泥浆制备花岗岩废砂粉,并将其作为细骨料和胶凝材料应用于水泥基材料中。本文概述了花岗岩废砂粉的物理和化学特性,在此基础上,综述了花岗岩废砂粉分别作为细骨料和胶凝材料,对水泥基材料的工作性、力学性能、抗渗性、抗硫酸侵蚀、抗硫酸盐侵蚀以及抗钢筋锈蚀等性能的影响和作用机理,分析了掺花岗岩废砂粉水泥基材料现阶段研究中存在的不足,这为花岗岩废砂粉的高效和高附加值资源化利用提供支持。

Abstract: During the processing of granite stone, a large quantity of waste slurry is produced. The random dumping of waste slurry will do harm to the environment and human health. In recent years, several researchers investigated the use of granite waste sand and powder (GWSP), produced from granite waste slurry, as fine aggregate or cement replacement in cement-based materials. This paper presented the comprehensive overview of the physical and chemical properties of the GWSP. Based on this, the effect and mechanism of GWSP as fine aggregate or cement replacement on the workability, mechanical property, anti-permeability and durability, such as water permeability resistance, chloride permeability resistance, sulphuric acid attack resistance, sulphate attack resistance and reinforcement corrosion of cement-based materials were reviewed. The limitations of the existing studies were analyzed, which will be beneficial for the efficient and high-value-added utilization of GWSP.

Key words: granite waste sand, granite waste powder, cement-based material, physicochemical property, workability, mechanical property, durability
