A number of porous models having the similar statistical characteristics of pores and physical properties with natural sandstones have been produced using reactive powder concrete (RPC) and polystyrenes. Spit-Hopkinson-Pressure -Bar tests and CT scans have been carried out on the models with the various porosities to probe the performance of wave propagations and the responses of pores and the mat...<br/><br/>Y Ju, Y M Yang, Y Z Mao, H B Liu, H J Wang (2009) <i>Science China (Series E)</i> 52: 5 1374-1389 <br/>

A number of three-point bending and fracture tests of 200 MPa-level reactive powder concrete (RPC) with the various fiber contents have been conducted to probe the nature and characteristics of tough-ness of RPC200. The contribution of the embedded fibers to improving the crack-resistant capacity, energy absorption capacity and toughness with various deformation mechanisms has been analyzed.

The geometric features and the distribution properties of pores in rocks were in-vestigated by means of CT scanning tests of sandstones. The centroidal coordi-nates of pores, the statistic characterristics of pore distance, quantity, size and their probability density functions were formulated in this paper. The Monte Carlo method and the random number generating algorithm were employed to generat...<br/><br/>Y Ju, Y M Yang, Z D Song, W J Xu (2008) <i>Science China (Series E)</i> 51: 11 2040-2058 <br/>

Reactive powder concrete (RPC) is a novel cement-based composite material with ultra-high strength. Embedding a certain amount of short steel fibers in the matrix can improve the RPC’s toughness and overcome the disadvantage of high brittle-ness. In this paper, a number of direct uniaxial tension tests have been carried out with ‘8-shape’ RPC200 specimens. The bond-slip process, mesoscopic s...<br/><br/>Y Ju, Y D Jia, H B liu, J Chen (2007) <i>Science China (Series E)</i> 50: 6 815-832 <br/>

This paper presents the experimental and theoretical investigation of property of stress wave propagation in jointed rocks by means of SHPB technique and fractal geometry method. Our aim focuses on the influence of the rough joint surface configuration on stress wave propagation. The comparison of behavior of reflection and transmission waves, deformation and energy dissipation of a rough joint su...<br/><br/>Y Ju, L Sudak, H P Xie (2007) <i>International Journal of Solids and Structures</i> 44: 13 4256-4271<br/>
