摘　　要：为研究不同因素对煤矸石水泥净浆流动性的影响，通过取水料比、煤矸石用量、减水剂用量为因素进行试验。根据试验结果分析可知，流动度随煤矸石用量增大而减小，当水泥与煤矸石的比例在1：1～1：2之间时下降较快。流动度随减水剂用量增大而增大，当用量大于1．2％时，其增长速度急剧加快，随水料比的增大而增长，在0．40～0．42之间，增长最快。In order to study the influence of the different factors on the fluidity of gangue cement paste,the water-aggregate ratio,gangue content and water reducer content are tested.The result shows that the fluidity is decreased with the increment of gangue content,and is more quickly reduced when the ratio of cement and gangue is between 1:1 and 1:2.The fluidity is increased with the increment of water reducer content,and its increment speed is rapid when the content is larger than 1.2%.The fluidity is increased with the increment of water and aggregate ratio,and its increment is the fastest between 0.40 and 0.42.
