Characterization of Mechanical Properties of Waste Slurry Modified by Recycled Sand and Cement with the increase of recycled sand content; recycled sand can enhance the shear strength of CWS by increasing both cohesion and internal friction angle. Th... B Lv,N Li,H Kang,... - 《Journal of ...
To ensure proper traction and bonding with the concrete, fine-grained sand was applied to the bamboo culms before the bitumen dried, allowing the sand to adhere effectively. The mechanical properties of the bamboo as determined following the procedures given in ISO 22157 [24] are shown in Table...
The interface shear behaviors, including shear stress versus horizontal displacement, the interface cohesion, and friction coefficient were analyzed based on the test results. A simple, nonlinear model was proposed and verified. By using the test results, the model parameters were obtained, and then ...
at the same time, will cause a high reduction ofsurface frictionof pavement and contaminate the environment. Therefore, encapsulation rejuvenator inside-usage in asphalt is an alternative approach[7]. Pours sand was applied to encapsulate rejuvenator using epoxy resin[8]. The advantages of these cap...
The coefficient of friction measures the slickness of a surface. As a result, increasing the coefficient of friction of the surface is required to increase slip resistance. Slip-resistant concrete surfaces are created using anti-slip paints, additives, or silica sand. ...
Concrete, an integral part of a nuclear power plant (NPP), experiences degradation during their operational lifetime of the plant. In this review, the major causes of concrete degradation are extensively discussed including mechanisms that are specific t
Both wet and dry sand can be used with the same approach and their only difference is that much less dust is produced using wet sand, but in both cases a considerable amount of sand is left behind [139]. Tests have shown that the height of peak-to-valley of irregularities in the ...
the surface will be even less slippery. Another option is to add a grit or anti-skid additive directly to a film-forming sealer as it's applied. There are several different types, ranging from clear polymer or plastic grit to white silica sand (seeMaking Concrete Slip Resistant). These add...
(2) Since the coefficient of friction between rebar and concrete is difficult to be determined quantitatively, only qualitative sorting was used according to the surface roughness to distinguish sand-coating surfaces, rusted surfaces, ordinary surfaces, epoxy-coated surfaces, zinc-coated surfaces, etc....
