Abstract

The invention provides C70 self-compaction concrete and a preparation method thereof. The C70 self-compaction concrete has high strength and self-compaction performance. According to the concrete, traditional gravel is replaced by basalt which is hard, good in gradation and lower in water absorption, and not only is the strength of the concrete ensured, but also a factory slump of the concrete canbe effectively controlled. The preparation method of the concrete is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a C70 self-compacting concrete and a preparation method thereof. Background technique [0002] Concrete filled steel tube has high bearing capacity, good plasticity and toughness, convenient construction and remarkable economic benefits. It is called the fifth largest structural system in civil engineering. It has been widely used in high-rise structures and long-span structures in recent years. Vibration technology has always been a difficult point in its construction and a research hotspot. [0003] At present, many research institutes have carried out a series of research work on the preparation and construction technology of its core concrete materials. They all focus on the ratio of raw materials and other issues, but even with the supplementary vibration technology, it is difficult to ensure the compactness of CFST. [0004] In view of this, the present inventi...
