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。作者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碳化性能,进而为评价干拌自密实混凝土的耐久性提供了试验依据。
Dry mix self-compacting concrete is developed 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,stirring uniformly, dry mix self-compacting concrete doesn＇t need mix design.Based on the study of mechanical properties ,the author studies the resistance to carbonizing of dry mix self-compacting concrete ,which can provide experimental basis for evaluating the durability of dry mix self-compacting concrete.
