我国公路建设和建筑工程中经常要进行一种测定混凝土强度的试验,用过去的老方法,需要二十八天。为了改变这一落后状况,交通部公路科学研究所和江苏省无锡县查桥建筑机械厂联合研制成一种新的机械设备:“JC-84-I型混凝土湿筛砂浆震动筛分、成型两用机(以下简称两用机)。1984年12月,在无锡县建筑机械厂,经有关单位试用验证合格。
In China’s highway construction and construction projects, a test to determine the strength of concrete is often conducted. It takes 28 days to use the old methods of the past. In order to change this backward situation, the Highway Research Institute of the Ministry of Communications and the Qiaoqiao Construction Machinery Factory of Wuxi County, Jiangsu Province jointly developed a new type of mechanical equipment: “JC-84-I type concrete shaker mortar shake screening, forming dual-use Machine (hereinafter referred to as dual-purpose machine) In December 1984, Wuxi County Construction Machinery Factory was tried and verified by relevant units.
