某火车站站房工程纤维混凝土的研究与应用

Study and application of a railway station building engineering fiber concrete

以广州新火车站站房工程为例,进行了纤维混凝土的专题研究,在专题研究的基础上,工程中采用了C30聚丙烯纤维混凝土,试验研究和工程应用表明,在C30混凝土掺加0.9 kg/m3的聚丙烯纤维,是一种有效提高混凝土抵抗早期开裂性能的技术措施。

With Guangzhou new railway station building engineering as example,the special study on fiber concrete was carried out.Based on the special research,the C30 polypropylene fiber concrete was adopted in engineering.The experimental study and engineering application indicated that mixed with 0.9 kg/m3 polypropylene fiber in C30 concrete was an effective technical measure to enhance concrete early cracking resistance.
