在毛主席的革命路线指引下,我们“三结合”研究小组,对福州地区存在的大量沸腾炉渣制造无熟料水泥(以下简称沸渣水泥)与空心砌块进行研究。通过无熟料水泥试验和以沸渣水泥为胶结料,煤渣、河砂为集料的混凝土强度试验,初步取得了成果。沸渣水泥蒸养后标号可稳定在400号左右,煤渣混凝土蒸养后标号可达150号以上。 Under the guidance of Chairman Mao’s revolutionary route, our “three-in-one” research team studied the production of clinker-free cement (hereinafter referred to as boiling-slag cement) and hollow blocks with a large amount of boiling slag that existed in Fuzhou. Through the tests of clinker-free cement and cement with boiling slag as binder, the strength of concrete with coal cinder and river sand as aggregates has achieved preliminary results. After steam boiling, the number of steamed cement can be stabilized at about 400, and the number of steamed concrete after steaming can reach 150 or more.
