摘要
通过矿物掺合料、高性能减水剂、水胶比、砂率、胶凝材料用量和粗骨料等因素对混凝土工艺性能、力学性能及耐久性能影响的试验研究,采用525号硅酸水泥、超细矿物掺合料和与之相适应的高性能减水剂,可十分成功地制备出抗压强度90~100MPa、坍落度20cm以上且2h无坍落度损失的高强高性能混凝土。
Through studying the effect of the factors, such as mineral active addition, water cementratio, sand percentage, usage of cementing material, coarse aggragate etc, on the workablity,mechanics property and durability Of concrete, high performnce concrete wich compressivestrength 90-100MPa, slump upwards 20cm, and no slump loss in 2 hours, can be made byusing 525 portland cement super-finded mineral active addition and ataptable water reduce agent.
