干混自密实混凝土是在自密实混凝土的基础上发展出来的,在一些复杂、不易填充、不能振捣结构部位、大面积浇筑工作量大工期紧的工程中得到了大量应用,具有简便、实用性强等特点。本文介绍了该混凝土的配制方法和其在高层建筑中梁柱节点中的施工应用,使工程施工质量得到了很好的控制,证明该技术是一种具有参考价值的节点浇筑新方法。 Dry mixed self-compacting concrete is developed on the basis of self-compacting concrete. It has been widely used in some complex, difficult to fill, can not vibrate the structural parts, a large area pouring workload of a tight schedule, with a simple, practical Sexuality and other characteristics. This paper introduces the preparation method of the concrete and its application in the construction of beam-column joints in high-rise buildings. The construction quality is well controlled. It proves that the technique is a new method of pouring joints.
