一、前言 水运工程现场浇注的混凝土或者是预制构件的混凝土强度,在其部位的垂直方向分布是不均匀的,探讨其分布状况,掌握和了解强度的变化,对水运工程的结构设计和调整施工中的混凝土配合比都有着极其重要的意义。本文在检查水运工程混凝土预制构件“松顶”的基础上,利用回弹仪、超声波两种方法探测了混凝土强度沿其构件垂直方向
I. Introduction Concrete strength of prefabricated concrete or prefabricated cast-in-situ concrete is unevenly distributed in the vertical direction of its site. The distribution of the concrete is analyzed to understand and understand the change of strength. The structural design and adjustment of the construction of the water transport project In the concrete mix has a very important significance. On the basis of checking the “loose roof” of prefabricated concrete components of water transport projects, this paper uses the two methods of rebound hammer and ultrasonic to detect the strength of concrete along the vertical direction of its components
