In recent years, various mineral admixtures such as fly ash, blast furnace slag, silica fume along with superplasticizers have been used to produce concrete with high strength and durability.

近年来，人们采用低水胶比，掺加粉煤灰、磨细矿渣和硅灰等矿物掺合料和高效减水剂的方法配制高强混凝土，但对高强混凝土的体积稳定性缺乏系统的研究，在工程实践中高强混凝土的收缩开裂问题也显得比较突出。

The SCC has the following advantages: remarkably reducing the noisy pollution and the worker s labor intensity in construction, deducing the rough surface or segregation because of missing-vibration or excessive-vibration in conventional construction, resolving the quality-defect problems resulting from lacking-vibration in the section of complex shapes and densely-packed reinforcement area. At the same time, large of industrial solid waste such as fly ash and blast furnace slag is utilized in the proportioning of SCC. It is helpful in comprehensive utilization of resource and environment protection, so the SCC belongs to "green concrete", it is a branch of HPC which will be developed in the future.

这种混凝土可以显著降低混凝土施工中的噪音污染；大幅度减轻工人的劳动强度；减少传统混凝土施工中因漏振或过振造成的麻面或离析；解决了配筋密集、结构复杂部位因振捣不足而造成的质量缺陷问题；同时，由于自密实混凝土在配制中，大量利用粉煤灰、高炉矿渣等工业固体废弃物，有利于资源的综合利用和生态环境的保护；从而被誉为&绿色混凝土&，是未来混凝土向高性能发展的方向之一。
