莫斯科石棉加工联合企业会同其它单位进行了采用热电站细粉煤灰代替10%波特兰水泥的生产性试验。粉煤灰的干容重为2.21克/厘米~3,‘比麦面积2,500厘米~2/克;化学成分为:SiO_250.74;Al_2O_3+TiO_20.35;F_2O_35.56%;CaO4.52;MgO(?).93;SO_30.2;烧失量16.61%。用粉煤灰代替水泥制作水泥石棉板是在莫斯科石棉加工联合企业第四工厂压制的,其混合料的组成为:水泥900公斤,П-3-50号石棉36公斤,П-5-50号石棉140公斤,干的粉煤灰100公斤。经过两次在工艺线上试
The Moscow Asbestos Processing Consortium and other units conducted production trials using thermal power plant fine fly ash instead of 10% Portland cement. The fly ash has a dry bulk density of 2.21 g/cm~3, and has a specific wheat ratio of 2,500 cm~2 g; chemical composition: SiO_250.74; Al_2O_3+TiO_20.35; F_2O_35.56%; CaO4.52; MgO ( ?).93; SO_30.2; Loss on ignition 16.61%. The use of fly ash instead of cement to make cement asbestos panels was suppressed at the fourth factory of the Moscow Asbestos Processing Joint Venture. The composition of the mixture was 900 kg of cement, 36 kg of asbestos П-3-50, and П-5-50 140 kg of asbestos and 100 kg of dry fly ash. After two trials on the process
