Comparative Analysis of Concrete Strength Control in China, USA and Europe

Abstract

This paper compares and analyses the differences in concrete strength control regulations in China, the United States and Europe. By comparing the inspection and acceptance standards of different countries' regulations, the differences in curing and solidification of standard specimens and statistical acceptance are analyzed. The principles and mechanisms of concrete strength control regulations in different countries are studied, and the similarities and differences in concrete strength control between China, the United States and Europe are compared. The results show that although there are some similarities, there are still significant differences in sampling frequency, acceptance standards, inspection effectiveness and strength control among different countries. Through comparing and analyzing the regulations of different countries, this paper better grasps the principles and experiences of different countries in concrete strength control, providing a global perspective and promoting the reasonable formulation of concrete strength inspection regulations in various regions for researchers and practitioners in the concrete industry.
