本文通过参照相关国家标准试验方法,对不同原材料性能的情况下,碳酸钠-矿渣-熟料胶凝材料的标准胶砂强度进行研究,试验发现一定范围内,矿渣掺量的提高会降低这种胶凝材料的早期强度,但后期强度会随矿渣掺量增加而增加,随熟料细度提高,碳酸钠-矿渣-熟料胶凝材料体系早期强度提高,但影响不显著,随碳酸钠掺量提高,体系早期强度提高,后期强度随碱掺量提高而降低。
In this paper, by referring to the relevant national standard test methods, the strength of standard mortars of sodium carbonate-slag-clinker cementitious materials is studied under different raw material properties. The test found that within a certain range, the increase of slag content will reduce this The early strength of cementitious materials, but the late strength will increase with the increase of slag content. With the increase of clinker fineness, the early strength of sodium carbonate-slag-clinker cementitious material system is improved, but the effect is not significant, and it is mixed with sodium carbonate. When the amount is increased, the early strength of the system is improved, and the late strength decreases with the increase of the alkali content.
