快速,准确地检测现场硬化混凝土强度和未凝固混凝土的28天潜在强度,对于适时掌握混凝土施工速度、保证施工质量、预防事故、节约水泥具有重要的意义。为此,我局组织了十一位同志参加了由中国水力发电工程学会施工专业委员会举办的“射钉法检测硬化混凝土强度和混凝土快速测强”新技术转让学习班。现将两种新技术介绍如下。一、射钉法检测硬化混凝土强度
The rapid and accurate detection of the 28-day potential strength of in-situ hardened concrete and non-solidified concrete is of great significance for timely mastering of concrete construction speed, ensuring construction quality, preventing accidents, and saving cement. To this end, the Bureau organized eleven comrades to participate in a new technology transfer class for “Scear nail testing for hardened concrete strength and rapid concrete strength testing” organized by the Construction Professional Committee of the China Hydroelectric Engineering Society. The two new technologies are introduced below. First, shot nailing test hardened concrete strength
