某立交桥混凝土连续梁C50混凝土配合比设计

Mix Design and Construction for C50 Concrete in Continuous Beam of Some Cloverleaf Junction

C50混凝土广泛运用于桥梁的上部结构中,由于混凝土配合比设计不合理,往往引起混凝土强度不合格、收缩裂缝等问题发生。某立交桥连续梁所需C50混凝土要求非常高,根据大量的试验以及成功的生产经验,阐述了C50混凝土的原材料选择以及配合比设计。

C50 concrete is widely used in the upper parts of bridges. The unreasonable design of mix design of the concrete may often cause the disqualified strength of concrete and shrinkage cracks. The continuous Beam of some cloverleaf junction requires super high - strength concrete. According to a large number of experiments and successful experience, this article introduces choice of the raw materials of C50 concrete and its mix design.
