摘要

以钢渣为研究对象，分别用硅酸钠、硫酸钠、碳酸钠、硫酸和醋酸激发钢渣的胶凝活性，依据相关标准测定了7 d和28 d时的活性指数. 结果表明，水玻璃、碳酸钠和醋酸可较好地激发钢渣胶凝活性，水玻璃掺量为1.6%(?)、碳酸钠掺量为2.4%(?)和醋酸浓度为0.10 mol/L时，激发钢渣胶凝活性最佳. 硫酸钠和硫酸对钢渣具有良好的活性激发作用，尤其早期对钢渣活性激发效果更好，硫酸钠掺量为3.2%(?)和硫酸浓度为0.10 mol/L时，激发钢渣胶凝活性最佳.

Abstract

Steel slag as the research object, steel slag cementitious activity was excited by sodium silicate, sodium sulfate, sodium carbonate, sulfuric acid and acetic acid, respectively. According to relevant standard, the activity index was measured after test for 7 and 28 d. The results showed that sodium silicate, sodium carbonate and acetic acid can better excitation steel slag cementitious activity, the steel slag cementitious activity was best with sodium silicate 1.6%(?), sodium carbonate 2.4%(?) and acetic acid 0.10 mol/L. Sodium sulfate and sulfuric acid can excited steel slag cementitious activity good, especially in the early stage, the steel slag cementitious activity was best with sodium sulfate 3.2%(?) and sulfuric acid 0.10 mol/L.

Key words： steel slag; activator; steel slag cementitious activity; chemical excitation; cementitious materials
