摘　　要：因含钛高且其主要活性组分CaO主要以钙钛矿形式存在,攀钢生产的高钛型高炉渣(HTTCS)活性很低。高汰型高炉渣生产墙体材料技术的研究重点是如何激发HTCS的活性,用其生产墙体材料-实心砖和混凝土空心砌块。研究表明,当采用80℃湿热养护并掺入适量的煅烧石膏和粉煤灰后, HTCS的活性可以充分地激发出来。当采用破碎的慢冷HTCS作为粗集料,水淬粒化HTCS作为细集料,制成的实心砖和混凝土空心砌块强度达到15 MPa(MU15)和10 MPa(MU10)。且墙体材料的耐久性指标和HTCS的放射性指标均满足国标要求。The reactivity of High Titanium Content Slag (HTCS) produced by Panzhihua Steel Company is very low because of its high content of TiO2 and the main reactive component CaO being in a state of perovs kite . This study focuses on activating the reactivity of HTCS and using it to produce wall materials - solid brick and hollow concrete block. The test results show that the reactivity of HTCS can be well activated by incorporation of lime, calcined gypsum, flyash together with thermal treatment at a temperature of 80℃. When adopting crushed natural cooling HTCS and granulated HTCS as aggregates, the solid brick and hollow concrete block can be successfully made with strengths higher than 15 MPa ( MU15 ) and 10 MPa (MU10) respectively. Both durability properties of the two wall materials and radioactive indexes of HTCS meet the national standards ' prescription.
