摘要
介绍采用秦皇岛浅野水泥有限公司生产的浅野P.O.42.5R水泥,选用优质的骨料,掺入活性掺合料、高性能减水剂制备出强度等级为C60～C80的混凝土,并适于泵送工艺。深入研究了掺合料、减水剂等各种因素对混凝土性能的影响。
The paper describes the production of high strength concrete of C60-C80 with Asano P.O.42.5 cement produced by Qinhuangdao Asano Cement Mill Ltd.,adopting quality aggregate,active admixtures and high perfomance water reducing agent,which is fit for delivery by pumping. In-depth studies are carried out on the influence of admixture,water reducing agent and other factors upon the performance of the concrete.
