1978年10月9日至13日在维也纳召开了第九届国际混凝土和预制构件工业会议,来自45个国家的代表参加了会议,发表了论文(报告)近百篇。这些报告充分反映了国际混凝土和预制构件工业的现状、存在问题和今后的发展趋势。会议根据报告的不同内容分六个专题进行。现将各专题会的情况简要报道如下: 1、混凝土工艺。交流了国际上在混凝土工艺方面新的科学认识和实践经验。有的报告提出,应当把抗拉裂强度作为混凝土砌块的质量标准,只把抗压和抗拉强
The 9th International Industrial Conference on Concrete and Precast Components was held in Vienna from October 9th to 13th, 1978. Representatives from 45 countries attended the conference and published nearly 100 papers (reports). These reports fully reflect the status quo, existing problems and future development trends of the international concrete and prefabricated component industries. The conference was divided into six topics according to the different contents of the report. The briefings of the conferences are now summarized as follows: 1. Concrete craftsmanship. Exchanged new international scientific knowledge and practical experience in concrete technology. Some reports suggest that the tensile strength should be used as the quality standard for concrete blocks, and only compressive and tensile strengths should be used.
