机制砂超高强高性能混凝土的研制

Study of Super-high Strength Machine-made Sand High-performance Concrete

作者采用常规材料及通用工艺成功地研制成工作性较好 ,2 8d抗压强度在 10 0MPa以上的机制砂高性能混凝土。文章在分析讨论了超细掺合料、水泥品种、标号及水胶比 ,超塑化剂的种类及掺量 ,胶结材用量 ,粗骨料的强度及粒径大小等配比参数对超高强高性能混凝土工作性及强度的影响后 ,指出了配制这种混凝土的技术途径。

? With the routine materials genceral technique the author successfully researched and manufactured the 28 day compression strength of the concrete is more than 100MPa.The paper points out the technique way which compounds the high performance concrete after analyzing and discussing the charge ratio parameters' influence upon the flow ability if super high strength high performace concrete.These parameters include super fine powder additives,cement sort,cement mark,water binder ratio,variety and mixture quantity of super plasticizer,utility quantity of binding materials,strength and particle diameter of coarse aggregate,etc. 〔
