公路桥面补偿收缩混凝土配合比设计

Mix Proportion Design of Compensating Shrinkage Concrete for Highway Bridge Deck

补偿收缩混凝土是在大幅度提高普通混凝土性能的基础上采用现代混凝土技术制作的混凝土,是以减少裂缝作为设计的主要指标,具有高工作性、高体积稳定性、高强度、高耐久性等特点。结合樟树市赣江二桥工程桥面接缝混凝土设计和施工,介绍补偿低收缩混凝土设计的思路、步骤及配制控制要点。

The shrinkage compensating concrete is greatly increase in making use of modern concrete technology based on the properties of ordinary concrete,its main index of design is to reduce crack,which has the characteristics of high performance and high volume stability,high strength and high durability etc.This paper introduced the low compensation shrinkage concrete design ideas,steps and preparation of control points combined with concrete design and construction of bridge joints about Zhangshu City Gan River Bridge.
