Abstract | Cable bolts as one of the most common means of ground support in surface and underground projects are attracting more attention due to their advantages over more expensive and cumbersome support elements. Thus, newer cables with new configurations and surface properties are emerging on a regular basis. Conventionally, the performance of cable bolts is studied in two main categories of axial and shear load transfer mechanisms. This paper focuses on the former by developing and proposing an experimental plan to cast light on the effect of surface profile on axial performance of cable bolts. Consequently, 15 representative surface profiles were designed and machined on metal base plates using a CNC machine. Later, these plates were used as moulds for casting cylindrical samples of Stratabinder cementitious grout. Three curing times of one day, 7 days, and 28 days were studied under static compression loading. It was observed that the surface roughness of the samples plays a major role in failure as it inhibits free movement of grout metal interface and inflicts end effect as well as introducing stress concentration point. These two drastically reduce the performance of grout and cause tensile crack growth. |
