The bond strength is the mobilized shear resistance along the rock-grout interface. From experience, it is known that for drilled and grouted anchors, the bond strength is affected by the: size of the grouted zone. As previously mentioned, the case of anchorages installed in rock …
Aug 11, 2013 Reference IS-9143-1979-Method for the determination of unconfined compressive strength of rock materials Objective The objective of this test is to determine unconfined compressive strength of rock. This test is primarily done to classify the rock on the basis of strength. Apparatus used Name of equipment Capacity Least count/Accuracy Loading Machine 5000 kN 2.5 N Vernier […]

The characteristic strength of concrete is the result of the compressive strength of the concrete cube test. The design strength is the required strength of concrete to be designed as per the IS code. For example, assume that the strength of concrete required M25, and the target design strength …
Dec 24, 2020 Calcareous sand is characterized by low strength, multiporosity, and high-pressure shrinkage. This often leads to poor engineering properties. Therefore, it is often necessary to reinforce the calcareous sand in order to meet the actual engineering demand for bearing capacity. To study the modification effect of calcareous sand of nanoclay by cement, mechanical tests and microscopic …
The bearing capacity of a homogeneous, and discontinuous rock mass cannot be less than the unconfined compressive strength of the rock mass around the footing and this can be taken as a lower bound for a rock mass with constant angle of internal friction 0 and unconfined compressive strength qur. Goodman (1980) suggests the following equation ...
