This number describes how much of a non-moving load a bar can take before it is crushed. Units are normally thousands of pounds per square inch. (10 psi) - Mega Pascals (mPa). Higher numbers indicate stronger materials which can withstand a heavier load before they break.

In compression testing, the ratio of maximum load to the original cross-sectional area. Fracture may or may not occur, depending on the applied forces and the properties of the material.

The measured resistance of a concrete or mortar specimen to loading in pounds per square inch {psi) The maximum compressive stress which Portland cement or concrete capable of withstanding.

The strength of a material against being crushed.

The stress a given material can withstand when compressed. Described in ASTM-D 695.

the ability of a material to resist breaking or being flattened if it is pushed or squashed.

The maximum compressive stress that a material is capable of developing, based on original area of cross section. If a material fails in compression by a shattering fracture, the compressive strength has a very definite value. If a material does not fail in compression by shattering fracture, the value obtained for compressive strength is an arbitrary value depending upon the degree of distortion that is regarded as indicating complete failure of the material.

The property of a material that confers resistance to a crushing force.

Ability of 'tufa to to withstand downward force or to sustain a heavy weight.

That property of an insulation material which resists any change in dimensions when acted upon by a compaction force. Compressive Strength is Important if the insulation must support a load or withstand mechanical abuse without crushing. If, however, cushioning or filling in space is needed as in expansion/contraction joints, low compressive strength materials are specified. Dyplast's ISO-C1 polyisocyanurate has excellent compressice strength, with successively higher density products exhibiting higher compressive strengths.

the stress developed at 5 or 10 percent strain in a uniaxial test.

The ability of a material to resist a crushing force.

A measure of the resistance of a material to a crushing load. Measured in pounds/square inch or megapascals.

The capacity to resist a crushing or buckling force; the maximum compressive load a specimen sustains divided by its original cross-sectional area.

Maximum load at which compression failure occurs in a specimen divided by the original area of the specimen.

The measured resistance of pavers to loads, referred to in pounds per square inch, and newtons per square millimeter.

The maximum compressive stress which a material is capable of sustaining. It is calculated from the maximum load during a compression test and the original cross-sectional area of the specimen. It is expressed in psi.(ASTM D1621)

and tensile strength. Strength is determined by how much weight a material can support or how much stress it can withstand. Compressive strength is the maximum stress that a material will bear when it is subjected to a load that pushes it together. Tensile strength is the maximum stress a material will bear when it is subjected to a stretching load.

The capacity of any material to withstand any crushing forces.

A material's ability to resist a force that tends to crush or buckle; maximum compressive load a specimen sustains divided by the specimen's original cross-sectional area.

the measured maximum resistance of a concrete or mortar specimen to axial compressive loading; expressed as force per unit cross-sectional area; or the specified resistance used in design calculations

Strength to resist outside pressure (as distinguished, for example, from bending or stretching forces).

The measured resistance of a concrete or mortar specimen to axial loading expressed as pounds per square inch {psi) of cross-sectional area. The maximum compressive stress which material, portland cement, concrete, or grout is capable of sustaining.

The average value of the crushing strengths of a sample of bricks tested to assess load bearing capability

The maximum compressive stress a material is capable of developing. With a brittle material that fails in compression by fracturing, the compressive strength has a definite value. In the case of ductile, malleable, or semiviscous materials (which do not fail in compression by a shattering fracture), the value obtained for compressive strength is an arbitrary value dependent on the degree of distortion that is regarded as effective failure of the material.

The ability of a material to resist a force that tends to crush it.

The ability of materials and components to resist deformation or other damage caused by the weight of compression of either live or dead loads.

The measured maximum resistance of a concrete paver to loading expressed as force per unit cross-sectional area such as pounds per square inch or newtons per square millimeter (megapascals).

The maximum stress a material can sustain under crush loading. It is calculated by dividing the maximum load by the original cross-sectional area of a specimen.

The maximum compressive stress concrete or cementitious overlay materials are capable of sustaining, expressed as pounds per square inch (psi).

The ability of concrete to resist compression forces, or pushing together forces, expressed in pounds per square inch (psi)

The degree of resistance of a material to a force acting along one of its axes in a manner tending to collapse it. Usually expressed in pounds of pressure per square inch (psi) of surface affected.

Crushing load at the failure of a specimen divided by the original sectional area of the specimen.

The ability of a structural material to withstands squeezing forces. The maximum compressive stress which material, Portland cement, concrete, or grout is capable of sustaining.

The maximum compressive load that a specimen will support divided by the net cross-sectional area of the specimen.

Pressure load at failure of a shaped specimen divided by a cross-sectional area of the specimen, usually the original sectional area.

Compressive strength is the capacity of a material to withstand axially directed pushing forces. When the limit of compressive strength is reached, materials are crushed. Concrete can be made to have high compressive strength e.g. many concrete floors have compressive strength of 20.7 MPa.
