摘　　要：研究了造纸白泥在碱激发矿渣体系中的应用,讨论了水玻璃性能参数对碱-白泥-矿渣体系性能的影响规律。结果表明:固定掺量30%、水玻璃模数为1.5、碱含量10%～12%、溶矿比0.5左右时,性能最佳。同时,白泥主要为"微集料"和"微晶核"作用,其化学反应活性低。The application of papermaking lime mud in alkali activated slag system was studied and influencing law of the parameters of sodium silicate on mechanical performance of the composite containing lime mud and slag was discussed. The results show that when fixed dosage is 30%, the best performance can be reached, appropriate parameters should be taken as follows： the sodium silicate modulus 1.5, the alkali content of 10 % to 12 %, dissolved ore ratio about 0.5. Meanwhile time mud only takes a role of the ＂micro-aggregate＂ and ＂microcrystalline nucleus＂ iu the system due to its low chemical reactivity.
