摘要
以毛乌素沙地砂作为混凝土细骨料在沙漠地区的工程实践中具有较好的经济效益和较强的现实意义,通过混凝土配合比的正交试验,分析了水灰比、砂率及减水剂掺量对于沙地砂混凝土的抗压强度和工作性的影响,确定了混凝土的最佳配合比,并制备出工作性能较好、强度达到C45的沙地特细砂混凝土.
Making use of Mu Us sandy land sand iconcrete has economic benefits and practical significance in engineering practice in the desert areas.The paper makes an analysis of water-cement ratio,sand ratio and water reducer dosage’s influence on the compressive strength and workability of Mu Us Sandy land sand concrete through orthogonal experiment,works out the optimum mixture ratio,and produce the C45 concrete which has good workability and strength.
