Strength is usually determined by means of test cylinders made of fresh concrete on the job and tested in compression at various ages. The requirement is a certain strength at an age of 28 days or such earlier age as the concrete is to receive its full service load or maximum stress. Additional tests are frequently

Collapse pressure (or PVC pipe crush strength) is the amount of outside pressure a pipe can take before it starts collapsing inwards. This is an important measurement when burying pipe for subterranean applications. To test this type of strength, you can place weight on a pipe until it starts buckling.
Tensile Strength. It is the force required to produce a rupture in a strip of paperboard, and measured in both machine direction & cross direction, i.e. parallel and opposite to grain direction. It is expressed in kN/m, and gives an indication of the ability of a paper to withstand stretching forces.
A cylindrical sintered metal slide bearing is used in at least one of a front bearing (16) and a rear bearing (17) that support a rotor shaft (14) of a motor (3) that is the rotary control drive source of a throttle valve (7) that controls the intake air flow to an internal combustion engine, and the bearing design is such that the relationship of the radial crushing strength and the ...
Compressive Strength Definition Compressive strength is the ability of material or structure to carry the loads on its surface without any crack or deflection. A material under compression tends to reduce the size, while in tension, size elongates.
The Cold Crushing Strength (CCS) represents the ability of a product to resist failure under compressive load at room temperature. It has an indirect relevance to refractory performance, and is used as one of the indicators of abrasion resistance. The higher the CCS of a material is the greater should be the resistance to abrasion.

Strength – The edge crush test allows manufacturers to check the strength of corrugated box. Material testing – The edge crush test allows the manufacture to test the quality of materials used in the production of corrugated boxes.
11 and 12 show the variation of compressive strength of fired samples containing bauxite and grog respectively compared with the maximum cold crushing strength of these samples. The presence of sodium citrate helped decreasing water required for mixing thereby decreasing the porosity of the samples and increasing their cold crushing strength .

Crushing Strength. Sometimes known as compression strength parallel to the grain, this is a measurement of the wood maximum crushing strength when weight is applied to the ends of the wood (compression is parallel to the grain). This number is a good indicator of the wood strength in applications such as deck posts, chair legs,. Live Chat
Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements.
Definition. The compressive strength of concrete can be calculated by the failure load divided with the cross sectional area resisting the load and reported in pounds per square inch in US customary units and mega pascals (MPa) in SI units. Concrete''s compressive strength requirements can vary from 2500 psi...

Compressive Strength. The compressive strength of any material is defined as the resistance to failure under the action of compressive forces. Especially for concrete, compressive strength is an important parameter to determine the performance of the material during service conditions.
Average of there specimens gives the crushing strength of concrete. In concrete compression test, normally 150mm x150mm x150mm . For normal concrete strength application, say below 50MPa, . the cube size of 150mmx150mmx150mm is already sufficient for the crushing strength of the machine.
