Mechanical properties and constitutive analyses of basalt fiber crumb rubber mortars in soft rock roadways

نویسندگان

چکیده

Uniaxial compressive stress-strain curves of several groups basalt fiber crumb rubber mortars (BF-CRM) with different contents are tested. By comparing the GZH model, improved values parameters BF-CRM constitutive model based on obtained. Then, taking supporting scheme main substation mine as background, using FLAC3D to simulate roadway support, replace ordinary in original and combining triaxial compression test confining pressure, application effect roadways support is studied analyzed.

Influence of Rubber Size on Properties of Crumb Rubber Mortars

Studies on the properties and applications of rubber cement-based materials are well documented. The sizes of rubbers used in these materials varied. However, information about the effects of rubber size on the properties of rubber cement-based materials, especially pore structure, mechanical strengths, and drying shrinkage properties, remains limited. Three groups of rubber with major particle...

Experimental Investigation of the Mechanical and Durability Properties of Crumb Rubber Concrete

Recycling waste tire rubber by incorporating it into concrete has become the preferred solution to dispose of waste tires. In this study, the effect of the volume content of crumb rubber and pretreatment methods on the performances of concrete was evaluated. Firstly, the fine aggregate and mixture were partly replaced by crumb rubber to produce crumb rubber concrete. Secondly, the mechanical an...
