‘They also have much higher compressive strengths than the concrete mix you are thinking of using.’
‘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.’
‘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.’
‘The results of field and laboratory testing indicated that the compressive strength of the silty clay ranged between 0.5 to 2 tsf.’
‘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.’
‘The main ‘Achilles heel’ of concrete is its relatively low tensile strength: only about one tenth of its compressive strength.’
‘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.’
‘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.’
‘They have a high compressive strength and fair resistance to erosion and scratch abrasion.’
‘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.’
‘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.’
‘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.’
‘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.’
‘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.’
‘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 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.’
‘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.’
‘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.’
‘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.’
