掺石灰石粉自密实混凝土性能的研究

Study on Performance of Self-compacting Concrete Mixed with Limestone-powder

研究了掺石灰石粉自密实混凝土的工作性能、力学性能和抗氯离子渗透性能。讨论了石灰石粉对高性能混凝土的影响,试验结果表明石灰石粉提高了高性能混凝土的工作性能和早期抗压强度,同时能有效地降低高性能混凝土的自收缩性能。

The self-compacting concretes(SCCs) with limestone-powder were prepared in this paper,and the workability,mechanics performance and the chloride resistance performance of SCC were researched,and we also discussed the limestone powder effect on the SCC.The test results showed that limestone-powder would improve the workability and early compressive strength of SCC,and at the same time the limestone powder would reduce self-shrinkage of SCC effectively.
