论文部分内容阅读
本刊自发表杜益彦同志“混凝土施工配制强度与结构安全度”(见1977年第9～10期)和冯文元同志“关于混凝土施工配制强度的意见”(见1978年第9期)两文后,陆续收到各地读者有关混凝土施工配制强度和混凝土强度质量验收标准方面的大量来信来稿,我们在这一期选登了其中四篇文章,供读者参考。由于本刊篇幅有限以及编辑部人力不足,其他来稿来信不能一一刊登和回函,特向投寄信稿的读者表示感谢并致歉意。目前有关部门正在积极组织《钢筋混凝土工程施工及验收规范》(GBJ10-65)的修订工作,其中关于混凝土强度质量标准的条文,由“混凝土质量控制和验收”课题研究组承担。读者有关这方面的意见和建议,可直接和北京市小黄庄中国建筑科学研究院建筑结构研究所规范室取得联系。
This publication has been published since the publication of Comrade Du Yiyan’s “Concrete Construction Strength and Structural Safety” (see pp. 9-10 of 1977) and Feng Wenyuan’s “Opinions on the Strength of Concrete Construction Mixing” (see No. 9, 1978). We have received a large number of incoming letters from readers around the country regarding the strength of concrete construction and acceptance standards for concrete strength. We have selected four of these articles for readers’ reference in this issue. Due to the limited space of this publication and the lack of human resources of the editorial department, other submissions cannot be published and written back. Special readers of the letter are thankful and apologetic. At present, relevant departments are actively organizing the revision of the “Code for the Construction and Acceptance of Reinforced Concrete Works” (GBJ10-65). The provisions on the concrete strength and quality standards are undertaken by the “Concrete Quality Control and Acceptance” task group. The reader’s comments and suggestions in this regard can be directly contacted with the Specification Office of the Institute of Building Structure, China Academy of Building Research, Xiaohuangzhuang, Beijing.
