The mechanical strength properties of cemented tailings backfill are very important for the safe and environmentally friendly mining mineral resources. To check impact polypropylene fiber on microstructure cementitious waste rock fill (CTWRF), diverse lengths (6 12 mm) dosages (0-control specimen, 0.3, 0.6, 0.9 wt.%) were considered to prepare fiber-reinforced CTWRF (FRCTWRF) matrices. Experime...

High price of land and importance modern construction has imposed the need to strengthen weak clay soils. The stabilization these soils been conducted using various additives. Due its low cost, availability, positive impact on resistance, lime traditionally applied for stabilisation poor sensitive types In this research, powder, added in percentages 0, 2, 4, 8 16 dry soil weight, was mixed with...

This study analyzed uniaxial compression strength over time by preparing a homogel specimen from a bio grouting material, a cement-like form produced by environment-friendly microbial reactions. Among chemical grouting methods, the most commonly used method is the Labile Waterglass method. In this study, the homogel uniaxial compressive strength of Labile Waterglass (LW) injection material and ...

On the basis of the pseudopotential plane-wave(PP-PW) method in combination with the local-density-functional theory(LDFT), complete stress-strain curves for the uniaxial loading and uniaxial deformation along the [001] and [111] directions, and the biaxial proportional extension along [010] and [001] of aluminium are obtained. During the uniaxial loading, certain general behaviors of energy ve...

Evaluating the structure of soil prior to building construction is valuable in a large variety geotechnical and civil engineering applications. To built an effective framework for assessing strength stabilised soil, presented workflow includes complex approach simplex lattice design X-ray diffraction analysis structure. Different from traditional situ measurements, we propose statistical decisi...

one important application of fiber reinforced polymer (frp) is to confine concrete as frp jackets in seismic retrofit process of reinforced concrete structures. confinement can improve concrete properties such as compressive strength and ultimate axial strain. for the safe and economic design of frp jackets, the stress-strain behavior of frp-confined concrete under monotonic and cyclic compress...
