| 摘 要： | 研究了掺入超磨细石灰石粉对超高强混凝土的力学性能的影响。结果表明,掺入10%的超磨细石灰石粉掺合料可显著提高混凝土的早期抗压强度,当石灰石粉掺量小于30%时,抗折强度随其掺量的增加而提高。

| Abstract: | In this article,authors study influences of addition of ultra-fine lime stone powder on mechanical properties of ultra-high-strength concrete.Test results indicate that adding 10 percent ultra-fine lime stone powder blending material can obviously improve the early compression strength of concrete,and that the bending strength of concrete will be improved along with increase of addition amount of lime stone powder when the addition amount is less than 30 percent. |
