Abstract Ultra-high performance concrete (UHPC) is currently a hot spot for domestic and foreign scholars, but there is no explicit specification for the UHPC mix ratio design. This papercomes up with a semi-empirical UHPC mix design based on theoretical analysis and experiment. Firstly, the cem...
Mix DesignPerformance Density DiagramsThe emergence of ultra-high-performance concrete (UHPC) as an attractive solution for precast and prestressed applications has coincided with global efforts towards sustainable construction. Tools capable of intuitively demonstrating the tradeoffs between mix proportions and...
The hotel’s lobby welcomes guests to a warm and nest-like space surrounded by floor-to-ceiling glass windows, which create a light box at night, as well as a feeling of seamlessness between indoors and out. The entrance to the hotel is framed with a mix of granite and limestone boulder...
超高性能混凝土(ultra-high performance concrete,简称UHPC)是一种高强度、髙韧性、低孔隙率的超髙强水泥基材叫UHPC基本配制原理是通过提高材料匀质性、降低孔隙率等方法尽可能的减少材料内部缺陷。其常用理论为无限填充理论，即用小颗粒填充大颗粒堆积时产生的缝隙，更小的颗粒填充小颗粒产生的缝隙,以此循环提高材料密实...

In recent years, the research on UHPC has become more and more in-depth, and it has become a hot field of concrete research at home and abroad. This article combines domestic and foreign research achievements from UHPC mix ratio design, ...
1. Generally, keep the original mix ratio and the stressed steel bar, no need to change. 2. Dosage: in general, about 0.9-1.9 kg/m3 of each cubic meter concrete. 3. Mixing: fibers can be added directly to the mixing system during or after the batching of the ingredients and mix...
Ultra high performance concrete (UHPC) is an advanced cementitious material, which exhibits high compressive, tensile, and durability characteristics [1]. The steel fiber in the mix design of UHPC enhance the tensile capacity after cracking of the cementitious matrix [2]. UHPC could be used as ...
