摘　　要：利用一种复合高效团体成性激发刺激发矿渣和赤泥，成功地研制出具有优良性能的城矿渣赤泥水泥。当水泥中矿渣与赤施之比为70:30.固体碱性激发剂的接加量为14况时，该水泥具有正常的凝结时间、良好的体积安定性和高的强度；初凝62min，终凝95min，净浆28d抗压强度达125MPa，砂浆28d抗折、抗压强度分别达到84MPa和56．OMPa。对我矿渣赤泥水泥其它工程性能的研究还表明，该水泥具有优于同标号硅酸盐水泥的抗干性能、抗碳化、耐冻融、和抗化学馒蚀性能。alkali - s1ag redclay cement with perfeet characteristic was successfully produced hom a component high efficient solid When slag and redclay in cement is 70: 30 and solid alkali agent addition is l4%, the cement is of normal setting time,good area workability and high strength' primary setting 62 min. Final setting 95 min. The compressive strength of net slurry 28d is l25mpa, and the comprehensive strength and bending strength of 28d mortar are resPeCtively 56. OmPa and 8. 4mpa.The study on its other engineering chara('teristic also shows that the slag redclay cement owns the advantages over the sazne grade cement against dried - up carbonization, unfreezing and chemical cormsion.
