1.前言日本于1973年由美国引进移动式混凝土连续搅拌装置,现已在各方面使用。目前在日本国内实际使用约有200台,出口其他国家约20台。在开始引进连续式搅拌机时,日本土木工程学会的混凝土标准示范书说明中指出:“连续式搅拌机因未具备向搅拌机连续提供规定配比物料的合适方法,而存在各种不稳定因素”,所以尚未批准连续式搅拌机的使用。但到1979年日本土木工程学会混凝土管理协会第三分会调查了连续式搅拌机的性能后,在同年11月,当日本土木工程学会修改
1. Introduction Japan introduced the mobile concrete continuous stirring device from the United States in 1973 and is now used in various fields. At present, there are about 200 units in use in Japan and about 20 in other countries. At the beginning of the introduction of continuous mixers, the Japanese Civil Engineering Society’s concrete standards demonstration book notes that: “The continuous mixer has various unstable factors because it does not have a suitable method of continuously supplying the prescribed material to the mixer.” The use of continuous mixers has not been approved. However, by the third branch of the Society of Concrete Engineers of the Society of Civil Engineers in Japan in 1979, the performance of the continuous mixer was investigated. In November of the same year, the Japanese Civil Engineering Society revised it.
