一种以电厂粉煤灰为主要原料制成的保温、抗裂、抗老化的新型粉状防水材料,近日由哈尔滨建筑工程学院研制成功。多年来,我国一直使用传统的三毡四油做法,施工工序多,污染危害大、返修率高。哈尔滨建筑工程学院建筑材料系经多年努力,以电厂粉煤灰做主要原料研制的建筑隔水粉,具有防水性能好、体轻、抗震、抗冻融、无毒无害,阻燃等特征。
A new type of powdery waterproof material made of fly ash as the main raw material for thermal insulation, crack resistance and aging resistance has been successfully developed by the Harbin Institute of Architecture and Engineering. Over the years, our country has been using the traditional three-felt and four-oil practice. It has many construction processes, and it has great pollution hazards and high repair rates. After years of hard work, the building materials department of Harbin Institute of Civil Engineering and Architecture has developed a water-repellent building powder made from the power plant fly ash as the main raw material. It has the characteristics of good waterproof performance, light weight, seismic resistance, freeze-thaw resistance, non-toxicity, and flame retardancy.
