矿粉对水泥-石灰石粉胶凝材料早期开裂的改善

摘要

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.
