在钢丝网水泥造船中应用减水剂,可取消或缩短蒸养时间,节省能源和水泥,提高水泥船的产质量,改善劳动条件,具有投资少、见效快、经济效益显著等优点。目前已在江苏、浙江、安徽、上海等省(市)推广应用。最近调查了18家水泥船生产单位,一年多来已用掺减水剂砂浆建造的船舶达13.21万吨,共计节煤4182吨,水泥199吨,增加收益25万多元。在水泥船生产中应用减水剂时,除选用减水剂类型、掺量和掺加方法外,关键问题
The application of water-reducing agent in steel mesh cement shipbuilding can eliminate or shorten the steaming time, save energy and cement, improve the production and quality of cement vessels, improve working conditions, and has the advantages of less investment, quick effect, and significant economic benefits. At present, it has been promoted and applied in Jiangsu, Zhejiang, Anhui, Shanghai and other provinces (cities). Recently, 18 cement ship production units have been surveyed. Over a year’s time, 138,100 tons of ships have been built with water-reducing mortar. A total of 4,182 tons of coal is saved, and 199 tons of cement are added, making an increase of more than 250,000 yuan. In the application of water-reducing agent in cement ship production, apart from the selection of water-reducing agent type, dosage and method of addition, the key issues
