摘要
介绍了超高性能自密实混凝土(UHP-SCC)的组成与性能特点。自密实性、自收缩开裂及高温爆裂是UHPSCC研发和推广应用的关键技术。超高泵送施工技术的难点是保塑、降黏和自密实性。UHP-SCC具有良好的技术经济效果及发展前景。
The composition and properties of UHP-SCC are introduced. The self-compacting,the selfshrinkage cracking and the high temperature explosion are the key technologies of UHP-SCC. The difficulty of high pumping technique is to preserve plasticity,reduce viscosity and self-compactness.UHP-SCC has good technique and economical effect and development prospect.
