CF60大掺量钢纤维泵送高强高性能混凝土的研制和应用

Research and application of CF60 steel fiber concrece with advanced intensity and performance

主要介绍了采用已鉴定的C60～C80高强高性能混凝土技术和常规的原材料,配制出CF60钢纤维泵送混凝土。在对搅拌楼上料系统部分进行了小规模的技术改造后,解决了钢纤维的易结团和分布不均等问题,并成功的大规模应用于国家重点工程中。

The CF60 steel fiber pumping concrete is mixed by adopting evaluated C60-C80 concrete technique of high intensity and perfor- mance,as well as the common materials.After small scope of technical reforming for entering material system in stir construct,the problem of steel fiber gathering into a mass and uneven distribution is solved.The technology is used for national-major project successfully and extensively.
