中文摘要：

以糖厂副产物甘蔗糖蜜为原料制备改性糖蜜，研究了其助磨性能及对水泥物理性能的影响。研究结果表明：改性糖蜜对水泥具有较好的助磨性能，显著降低45μm筛筛余量；改性糖蜜使水泥的凝结时间略有延长，可显著提高各龄期的抗压强度，28d抗压强度最多提高5.3MPa；水泥净浆流动度也较空白样增大。

英文摘要：

Modified cane molasses was prepared with waste cane molasses from sugar refinery,and the performance as grinding aids of modified cane molasses was studied. The influence of modified cane molasses on the physical properties of cement was also investigated. The research results show that modified cane molasses had good performance as grinding aids of cement, it can obviously reduce 45 μm sieve residue. The setting time of samples with modified of cane molasses was slightly prolonged,and the compressive strength at each age was increased significantly,especially the age of 28 d,can increase 5.3 MPa. The cement paste fluidity was also increased compared to the reference sample.
