由内蒙古建设厅立项、包头市新型建筑材料厂研制的DS系列混凝土、自动定量加水器,于1991年3月30日通过省级新产品技术鉴定。目前,多数建筑施工企业、构件生产企业由于搅拌机没有精度较高的定量加水装置,拌制的混凝土或砂浆或稀或稠的现象经常发生。山于混凝土水灰比不能保证,造成的质量事故时有发生。因此,保证混凝土拌制时准确加水,是节约水泥,确保质量的有效手段。 The DS series concrete and automatic dosing device developed by the Inner Mongolia Construction Department project and Baotou New Building Materials Factory passed the provincial-level new product technology appraisal on March 30, 1991. At present, most construction companies and component manufacturing companies do not have a high-precision quantitative water adding device because of the mixer, and mixed concrete or mortar or dilute or thick phenomenon often occurs. The water-cement ratio of concrete to concrete cannot be guaranteed, and quality accidents occur from time to time. Therefore, it is an effective means to save cement and ensure quality by ensuring accurate water addition during concrete mixing.
