一、简介硫铝酸盐自应力水泥是在毛主席革命路线指引下,由石家庄市水泥制品厂和国家建材总局建材院共同研制出来的新品种水泥。这种水泥是从无水硫铝酸钙和硅酸二钙为主要矿物组成的熟料与一定量的天然二水石膏混合粉磨或分别粉磨均匀混合而成。我厂用石家庄水泥制品厂的硫铝酸盐自应力水泥(B3.5)来试制硫铝酸盐自应力钢丝网水泥(砂浆)压力管,一九七五年九月试生产第一批4根φ800管,按照建材院的安排作长期水养观察。一九七八年三月二十二日又用已存放二年半的同批水泥,试用整体模涂蜡工艺,第二批生产了五根。
I. Introduction Sulphoaluminate self-stressing cement is a new type of cement developed jointly by Shijiazhuang Cement Products Factory and State Building Materials Bureau Building Materials Institute under the guidance of Chairman Mao’s revolutionary line. The cement is anhydrous calcium sulphoaluminate and dicalcium silicate as the main mineral clinker and a certain amount of natural dihydrate gypsum mixed grinding or grinding evenly mixed. I plant with Shijiazhuang cement products factory self-stress cement sulfate (B3.5) to trial self-stress steel wire mesh cement (mortar) pressure pipe trial production in September 1975 the first batch of 4 Root φ800 tube, in accordance with the arrangement of building materials for long-term aquaculture observation. On March 22, 1978, the same batch of cement, which has been stored for two and a half years, was used again to test the overall mold waxing process. In the second batch, five were produced.
