矿粉对水泥—石灰石粉胶凝材料早期开裂的改善

Mineral powder improving early cracking of cement-limestone flour cementing material

依据相关理论进行了砂浆抗裂性能试验,通过对试验结果的分析讨论,研究了矿粉对水泥—石灰石粉胶凝材料早期开裂性能的影响,结果表明矿粉可延迟水泥基胶凝材料的开裂时间,随着矿粉掺量的增加,延迟效果越明显。

According to relevant theories,the article carries out mortar anti-cracking performance test,analyzes experimental results,and studies the impact of mineral powder upon early cracking performance of cement-limestone flour cementing material. Results show that： mineral powder can delay cement cementing material cracking time： with the mineral powder increasing,the delay effect will be more obvious.
