Read MoreJan 21 2016nbsp018332reinforced concrete has a compressive strength in the region of 4000 psi and steel in the region of 25000 psi but in a typical concrete structure the compressive load is borne by the bulk concrete not the steel when the concrete fails it cr.
Read MoreFlexural tension failure initiates by yielding of steel reinforcement followed by crushing of concrete at compression side of the beam it occurs when the beam is underreinforced the reinforcement ratio in the beam is low than balanced reinforced ratio as per aci 318.
Read MoreHistorical strength test records are used by the concrete producer to establish the target average strength of concrete mixtures for future work how to test the strength of concrete cylindrical specimens for acceptance testing should be 6 x 12 inch 150 x 300 mm size or 4 x 8 inch 100 x 200 mm when specified.
