Numerical testing is an ideal method in the research on mechanical behaviors of jointed rock. However, there are few systematic studies focused comparison between two-dimensional (2D) and three-dimensional (3D) simulation effects rock behaviors, particularly those In this paper, a particle flow model was established by utilizing PFC2D PFC3D to represent materials, (especially rock) (uniaxial co...

The calcarenites carbonate rocks of the Quaternary ridges, which extend along the northwestern Mediterranean coastal plain of Egypt, represent an excellent model for the transformation of loose sediments to real sedimentary rocks by the different stages of meteoric diagenesis. The depositional and diagenetic fabrics of the rocks, in addition to the strata orientation, highly affect their ultima...

A laboratory study was conducted to investigate the borehole deformation of poorly cemented sandstone rocks with Uniaxial Compressive Strength (UCS) less than 10 MPa under different stress path regimes by using a convergence measuring device (CMD). Synthetic thick-walled hollow cylinders (TWHCs) comprised sand grains, Portland cement and water were prepared for this study. series mechanical tes...

The freeze-thaw (F-T) induced deterioration in rocks affects their durability, leading to various landslides, rockslides, and avalanches. study focuses on estimating loss rock strength using mineralogical properties under the influence of multiple FT cycles. samples were collected from F-T affected north Indian Himalayan region. specimens subjected conditioning (0th, 10th, 20th 30th cycles). (s...

Previously conducted studies have established that gaseous water sorption of mudstone is widespread in nature. The deterioration its uniaxial compression properties during can cause engineering problems. However, related were currently the initial stage this research direction. On one hand, there few on characteristics process. results might not be applicable to all projects. other microstructu...

Steel slag CO2 sequestration helps mitigate global warming and decrease the stockpile of steel (SS). Through orthogonal design tests single-factor tests, this paper evaluated effects water/solid mass ratio (w/s), gypsum (G/SS), molding pressure, curing duration on uniaxial compressive strength (UCS) uptake compacts. The results indicated that high w/s enhanced both capture ability. proper addit...

The reduction in uniaxial compressive strength (UCS) was investigated for sandstones under various moisture levels. Thirty-four UK Darney sandstone samples were tested six different conditions. time-dependent gain and loss also evaluated. For 77 identified the literature, of UCS between oven-dry saturated conditions up to 45%, with an average 20%. stone, around 20%, 72 N/mm2 when 58 fully satur...

The understanding of the mechanical properties sensitive marine clay subgrade stabilized with cement is vital for safe, economical, and durable design road structures. As curing temperature affects hydration progress, it necessary to investigate influence on evolution cement-reinforced in construction. A column testing relevant monitoring program were performed study effect various temperatures...
