近年来许多组织致力于研究水泥和混凝土工业中的节能问题。目前已取得成就的低能耗水泥质材料有粉煤灰,矿渣和火山灰等。最近人们开始注意可部份代替水泥的浓缩硅烟,这是因为硅烟在各国普遍增产,并且由于严格控制污染而停止向大气中散布所致,此外,有效的超塑化剂开创了用这种材料作为水泥补充材料的可能性。北欧诸国正在进行把硅烟用于混凝土中的研究工作。尤其是挪威和丹麦,这两国自1976年起已在 In recent years many organizations have devoted themselves to the study of energy conservation issues in the cement and concrete industry. The low-energy cementitious materials that have been achieved so far include fly ash, slag and volcanic ash. Recently, people started to pay attention to concentrated silicon fumes that can partially replace cement. This is because silicon fume is generally increased in various countries, and due to the strict control of pollution to stop the dissemination to the atmosphere, in addition, effective superplasticizers have been used to create this. The possibility of the material as a cement supplement. The Nordic countries are working on the use of silica fume in concrete. Especially Norway and Denmark, the two countries have been
