摘要
摘 要:铝合金模板是我国近年来新出现的一种新型模板系统,当对铝合金模板成型混凝土构件抗压强度进行推定时,采用回弹法这种非破损检测技术检测结果与混凝土实体强度存在较大的偏差,且这种偏差存在系统性。经过对混凝土成型过程的分析研究发现,引起系统性偏差的主要因素是铝合金模板成型的混凝土结构构件表层与构件内部在强度、空间结构等方面存在明显差异。
Abstract: Aluminum alloy template is a new template system in China in recent years, when the aluminum alloy template cast concrete compressive strength is assumed by rebound method, there is a large deviation between the results of rebound method and concrete solid strength, and this deviation is systematic. Through the analysis and research of the concrete forming process, the main influencing factors that cause systematic deviation are the obvious differences in strength and spatial structure of the concrete components between the surface and theinterior of components that molded by the aluminum alloy formwork.
