桥用高性能混凝土的制备、性能及其应用研究

Investigation of Preparation,Properties and Engineering Application ofHigh Performance Concrete for Bridge

高性能混凝土是一种满足特殊性能组合要求且均匀致密、具有优良的拌和物性能、力学性能和耐久性能的优质混凝土。高性能混凝土制备的主要技术途径是掺优质活性掺和料和高效减水剂,使高性能混凝土变得既经济又具有环境生态保护作用。本文研究掺I级粉煤灰、矿渣微粉和二者双掺的高性能混凝土(HPC)制备方法、工作性和力学性能,并在重点工程中得到了应用。

High performance concrete(HPC) is a special concrete with high workability mechanical properties and durability.Mixing excellent mineral component and Superplasticizer in ordinary performance concrete is the economical and ecological methods of preparing HPC.This paper mainly discusses the preparation methods,workability and mechanical properties of HPC mixing FA or blast furnace slag or together incorporating the FA and slag.
