COMPRESSIVE STRENGTH OF CONCRETE
iricen.gov.inThe measured compressive strength of the cubes shall be calculated by divid ing the maximum load applied to the cubes during the test by the cross-sectional area, calculated from the mean dimensions of the section and shall be expressed to the nearest 0.5 N/mm2. In determining the compressive strength, do

www.ce.memphis.eduStrength The specified compressive strength, ˘, at 28 days is the strength that is expected to be equal to or exceeded by the average of any set of three consecutive strength tests. ACI 318 requires for ø to be at least 17.5 MPa (2500 psi). No individual test (average of two cylinders) can be more than 3.5 MPa (500 psi) below the specified ...

Strength properties in directions other than parallel (P) or perpendicular (Q) to the grain can be approximated using a Hankinson type formula: where q is the angle to the grain. For bending and tensile strength, N ranges from 1.5 to 2, and for compressive strength from 1.5 to 2.0. For the modulus wood.a
