交通部公路科学研究所和水电部天津设计院科研所蔡正咏副研究员和李世绮工程师等研究成功“一小时推定混凝土强度“新技术”,可广泛应用于混凝土生产。经全国大部分省市、上百个单位的试验室和现减试用证明,采用这项新技术,只需要一小时就可推定过去经过二十八天才能测得的混凝土抗压强度,现减推定精度可以满足施工需要, Institute of Highway Science and Research, Ministry of Transport and Tianjin Institute of Technology’s Institute of Hydropower and Science, Institute of Science and Technology, Cai Zhengwei, Associate Researcher, and Li Shizhen, Engineer, etc., have successfully developed the “one-hour presumed concrete strength new technology”, which can be widely used in concrete production. Units of laboratories and proof of reduced trials, using this new technology, it takes only one hour to estimate the compressive strength of concrete that has been measured in the past twenty-eight days, and the current estimation accuracy can meet the construction needs.
