WHAT ARE THE FACTORS INFLUENCING COMPRESSIVE STRENGTH TEST ...
· Factors Affecting Strength Test Results of Concrete Compressive strength is the most important property of concrete. The compressive strength of concrete is determined in the laboratory in controlled conditions. On the basis of this test result we judge the quality of concrete. But sometimes the strength test results vary so widely that it becomes difficult [.]

The procedure is applied to a number of rock sample photos, which were taken as part of a data set of compressive and tensile strength testing on a variety of rock types. The individual influences are examined and the resulting effects on the value of "mi" are discussed.
Influences On Strength Of Rock
The shear strength of a discontinuity in a soil or rock mass may have a strong impact on the mechanical behavior of a soil or rock mass. The shear strength of a discontinuity is often considerably lower than the shear strength of the blocks of intact material in between the discontinuities, and therefore influences, for example, tunnel ...

Influence of water content on the strength of rock ...
· Water content is one of the most important factors influencing rock strength. Considerable research has been carried out to investigate rock strength under both dry and water saturated conditions. According to these results, the petrophysical properties of rocks decrease with increasing moisture and this can result in an increase in the mechanical compliance in some cases.

Practical Rock Engineering Chapter 4 Shear Strength of ...
Shear strength of discontinuities Introduction All rock masses contain discontinuities such as bedding planes, joints, shear zones and faults. At shallow depth, where stresses are low, failure of the intact rock material is minimal and the behaviour of the rock mass is controlled by sliding on the discontinuities.
