[摘要] 在自密实混凝土基础上发展起来的干拌自密实混凝土，其最大特点是主要材料（基料）的商品化生产，施工现场无需进行配合比设计，直接在基料中加入一定量水和粗集料，搅拌均匀即可。本文在前人对干拌自密实混凝土基本力学性能研究的基础上，研究了干拌自密实混凝土的抗氯离子渗透性能，进而为评价干拌自密实混凝土的耐久性提供了试验依据。

Abstract: Dry Mix Self-Compacting Concrete is based on Self Compacting Concrete, its most important feature is the commercial production of main materials( base material). Only adding some water and coarse aggregate, Stimng uniformly, Dry Mix Self-Compacting Concrete need not for mix design. Based on the study of mechanical properties, this thesis is a study about anti chloride ion permeation ability of Dry Mix Self-Compacting Concrete, which can provide experimental basis for evaluating the durability of Dry Mix Self-Compacting Concrete.
Keywords: self compacting concrete; dry mix self-compacting concrete; anti chloride ion permeation ability; durability
