摘要
根据慈母山隧道结构设计混凝土的强度,以及在特殊条件下混凝土的耐久性、和易性等技术要求,并结合本工程混凝土运输时间及气候条件、混凝土泵的性能、原材料的质量等实际情况,合理选用了原材料及其用量间的比例关系,从而设计出经济合理、质量好、泵送效率高的混凝土。
According to Cimushan tunnel structure design concrete intensity,concrete durability and easy performance technical requirement under special condition,combined with engineering concrete transportation time and climate condition,pump concrete performance,raw material quality practical situation,the ratio relation between material and its use level was chose rationally,therefore designed economic proper,better quality and high pump efficiency concrete.
