摘要
为了提高白沙包大桥现浇箱梁混凝土强度及耐久性,确保砼满足施工需要,达到改善施工条件,有效减少高标号混凝土因温度变化引起微裂纹,下面对C55聚丙烯腈纤维砼配合比设计进行简要总结。
In order to improve the cast--in--place box girder bridge Pak package strength and durability of concrete to improve the work conditions, effectively reduce the high--grade concrete due to temperature changes caused by micro--cracks, to ensure that the concrete construction to meet the needs of this paper, polyacrylonitrile fiber C55 concrete mix design a brief introduction.
