The strength of a rock will depend upon its - Quality The degree of weathering Presence of micro-cracks The strength of a rock mass will depend upon - The number of cracks and joints The nature of their infilling material

Basalt fiber - Wikipedia

The basalt fibers typically have a filament diameter of between 10 and 20 μm which is far enough above the respiratory limit of 5 μm to make basalt fiber a suitable replacement for asbestos. They also have a high elastic modulus, resulting in high specific strength—three times that of steel.

Compressive Strength - an overview | ScienceDirect Topics

Compressive strength is the standard strength parameter of concrete that can be evaluated under site conditions as well. The most common method is to use cylinder cores drilled off the structure. Momber (1998b) was probably the first to suggest to use the way how a cylinder fails during the compression test as a criterion of the material behaviour during hydrodemolition.

Compressive Strength Testing of Plastics - MatWeb.com

Compressive Strength Testing of Plastics. The compressive strength of a material is the force per unit area that it can withstand in compression. This is in contrast to the more commonly measured tensile strength.ASTM D695 is the standard test method in the USA.

As shown in Fig. 7, the dynamic compressive strength of all groups of concrete increases with increasing strain rate. At the strain rate range in this study, the dynamic compressive strength of BC-0.1, PC-0.1, and BPC-0.1 is greater than that of NC. At the low strain rate, the dynamic compressive strength of BPC-0.2 is lower than that of NC.
