The compressive strength of M20 grade concrete varies between 17 and 23 N/mm2 (i.e. between 170 kg/cm^2 and 230 kg/cm^2) after 28 days curing. This means that the concrete can withstand a compressive load of 170 to 230 kg/cm² before it fails.. In compressive strength test of concrete cube the push force applied on the both faces of concrete specimen and the maximum .ASTM C109 | Concrete | Compression Testing. Hydraulic Cement Mortars are typically formed by a combination of cement, sand, and water, but may include a variety of other materials in the mix. . ASTM C109 describes the methodology for testing the compression strength of mortars using cubes of material that are 2 inches on a side.Compressive Strength Test of Concrete. The compressive strength test of concrete is an essential procedure that helps engineers and construction professionals evaluate the strength and durability of concrete structures. The test is commonly done on concrete cubes, using a compressive testing machine to determine the maximum compression load the cube can .
Proper preparation is crucial as the ASTM C39 test method tests concrete cylinders to determine their compressive strength. The typical dimension of such cylinders is usually 4×8 inches or 100×200 mm.
