我国推广预拌混凝土,在本世纪初蓬勃发展。特别是近几年,国家和省有关部门相继出台政策,对城区“禁拌”推广预拌混凝土给予了高度重视与政策支持。葫芦岛市于2005年7月也出台了城区“禁拌”的政府令。这些举措鼓励预拌混凝土的发展,推动了全市预拌混凝土应用和城区“禁拌”工作 Promote ready-mixed concrete in our country, booming at the beginning of this century. In recent years, in particular, relevant departments of the state and the province have introduced policies in succession and attached great importance to and policy support for the promotion of ready-mixed concrete in urban areas. Huludao City in July 2005 also introduced the city “ban mixed” government order. These measures encouraged the development of ready-mixed concrete and promoted the city’s ready-mixed concrete application and urban “banning mixing” work
