| Abstract: | 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. |
