用促凝压蒸技术快速推定混凝土强度的研究课题,是由交通部公路科学研究所主持,有交通、铁路、水力、水电、火电、建工等九个部门参加协作共同研究。通过现场和室内大量试验,终于取得了用促凝压蒸技术1小时推定混凝土28天强度的科研成果。该成果为施工现场提供了一个简单易 The research project of rapidly predicting the strength of concrete by the method of coalescence and pressure steaming is presided over by the Highway Science Research Institute under the Ministry of Communications. There are nine departments such as transportation, railway, hydropower, hydropower, thermal power, construction and other departments participating in collaborative research. Through a large number of experiments in the field and in the laboratory, the scientific research results of 28-day strength of concrete were finally obtained by using the pre-coagulation and steaming technique for 1 hour. The result provides a simple and easy place for the construction site
