Definition of compressive strength in English:

compressive strength

Pronunciation /kəmˈpresiv streNG(k)TH/ /kəmˈprɛsɪv strɛŋ(k)θ/ /strenTH/ /strɛnθ/


  • The resistance of a material to breaking under compression.

    Compare with tensile strength

    ‘The compressive strength of a material is calculated as the pounds per square inch required to rupture the specimen or deform it to a given percentage of its height.’
    • ‘They have a high compressive strength and fair resistance to erosion and scratch abrasion.’
    • ‘Triaxial compressive strength tests show that saturation causes, in every metamorphic grade, an increase of angle of internal friction as well as a decrease of cohesion.’
    • ‘The main ‘Achilles heel’ of concrete is its relatively low tensile strength: only about one tenth of its compressive strength.’
    • ‘Workers initially stressed the tendons to 11 kips, then brought them to full tension with a second stressing when the concrete compressive strength reached 2600 psi.’
    • ‘The results of field and laboratory testing indicated that the compressive strength of the silty clay ranged between 0.5 to 2 tsf.’
    • ‘The opposite convention is, however, usually adopted for geomaterials (rocks and soils), because the tensile strengths of these materials tend to be low in comparison to their compressive strengths.’
    • ‘High-strength concrete, that is, compressive strengths of 12,000 to 14,000 psi, doesn't need air-entrainment, but it is often specified anyway.’
    • ‘Ductal-FO, with organic fibers, yields somewhat lower compressive strengths of 17,000 to 22,000 psi and flexural strengths of 2200 to 3600 psi.’
    • ‘Another advantage is strength: GFRC can have tensile and flexural strengths as much as seven times those of plain concrete, with compressive strengths as high as 14,000 psi.’
    • ‘In general, spray foam now utilizes densities nearer to 3 pounds per cubic foot than the previous 2 pounds per cubic foot, and higher compressive strengths as well.’
    • ‘The caissons, with concrete compressive strengths of 5000 to 6000 psi, were in good condition and are being reused.’
    • ‘A typical fire-rated lightweight mix calls for compressive strengths between 3500 and 4000 psi.’
    • ‘They also have much higher compressive strengths than the concrete mix you are thinking of using.’
    • ‘Through considerable pretesting, RMC-Cemex designed concretes that met the specified criteria but also had a low temperature gain, a high compressive strength, and a low coefficient of thermal expansion.’
    • ‘This study found that walls built with 1/4-inch joints had more than twice the compressive strength as walls built with 3/4-inch joints.’
    • ‘Because mineral density is directly proportional to the compressive strength of bone, the location of maximum load on a joint surface can be estimated by characterizing the local distribution of density on a joint surface.’
    • ‘In-place compressive strength also can be higher or lower than the standard lab-cured cylinder made from concrete sampled at the chute, depending on time and temperature of the in-place concrete.’
    • ‘The compressive strength is directly related to the density (lower density equals lower strength) and ranges from as low as 250 psi up to more than 3000 psi.’
    • ‘Cylinder testing revealed that the compressive strength of the concrete was 1000 psi lower than predicted, though it still met the specification requirements for the project.’
