蒸汽养护对高性能混凝土弹性模量的影响
Influence of Steam-curing on the Elastic Modulus of High Performance Concrete
摘要
Abstract
It is discovered that the elastic modulus of steam-curing box girder began to be decreased when box girder is removed for five days through filed testing of box girder of different ages. The elastic modulus of box girder twenty-eight days later can be calculated through the structure of younger age period and the relationship between elastic modulus and ages. Thus, the basis of time and new methods for optimizing the tension/extension of box girder's structure can be provided.关键词
