RISExperimental Investigation on the Performance of Cement Mortar by Partial Replacement of the Standard Sands with Sulfide-Contained Iron Tailings
Publisher: ASCE
Abstract: The usage of iron tailings as construction aggregates is a potential route to save the cost of standard sands and protect the environment of mining area. This study mainly investigates the performance of cement mortars by ...
Strength and Failure Characteristics of Rocklike Material Containing a Large-Opening Crack under Uniaxial Compression: Experimental and Numerical Studies
Publisher: American Society of Civil Engineers
Abstract: A series of uniaxial compression experiments was conducted on rocklike specimens containing a large-opening crack to investigate the effect of inclination angle and length of crack on the uniaxial compressive strength (UCS) ...
The Microscopic Pore Structure Change and Its Correction with the Macroscopic Physicomechanical Properties of Sandstones after Freeze–Thaw Cycles
Publisher: American Society of Civil Engineers
Abstract: Freeze–thaw damage of rocks causes many engineering problems in cold regions. During the cyclic freeze–thaw process, the frost-heaving pressure, which is produced by 9% volumetric expansion of pore water, will drive the ...
