一、前言 当今国内外对新拌混凝土的快测技术的研究愈来愈重视,它的最大特点是能及时控制混凝土质量,推算28天强度是否符合混凝土配合比设计的要求,如果达不到设计要求时,就可以及时分析原因,采取有效措施来保证设计要求。
I. INTRODUCTION The research on the rapid measurement technology of fresh concrete has been increasingly emphasized at home and abroad. Its greatest feature is the timely control of concrete quality. It is calculated whether the 28-day strength meets the requirements of concrete mix ratio design if it fails to meet the design requirements. When required, it is possible to analyze the causes in a timely manner and take effective measures to ensure design requirements.
