建设部标准《回弹法评定混凝土抗压强度技术规程》(JGJ23-85)(以下简称《规程》)系由建设部1985年1月22日批准,1985年8月1日试行。多年来已在全国大多数部门、地区推广使用。据多次调查表明,它在混凝土工程质量事故的处理中,精度满足要求,对处理及保证混凝土工程质量起到了积极的作用。但在推广执行过程中也感到《规程》的某些条文尚不完善,后由于国家标准《混凝土强度检验评定标准》(GBJ107-87)的批准与实施,使得相应的设计、施工规范要作修订,因而本《规程》也在修订之列。根据建设部城标字第141号文的通知要求,由陕西省建筑科学研究设计院会同中国建筑科学研究
The Ministry of Construction’s standard “Technical Specification for the Evaluation of Compressive Strength of Concrete by Rebound Method” (JGJ23-85) (hereinafter referred to as the “Regulation”) was approved by the Ministry of Construction on January 22, 1985 and implemented on August 1, 1985. For many years, it has been promoted in most departments and regions in the country. According to several investigations, it has met the accuracy requirements in the handling of concrete construction quality accidents, and it has played a positive role in handling and ensuring the quality of concrete works. However, during the promotion and implementation process, some provisions of the “Regulations” were still not perfected. After the approval and implementation of the national standard “Concrete Strength Inspection and Evaluation Standard” (GBJ107-87), the corresponding design and construction specifications were revised. Therefore, the Regulations are also being revised. According to the notification requirements of the No. 141 document of the Ministry of Construction of the Ministry of Construction, the Shaanxi Provincial Institute of Architectural Research and Design cooperates with the Chinese Academy of Building Sciences.
