Consider the following strengths of concrete:

Compressive strength test: Compressive strength of concrete is tested by preparing the mould of different shape which may be either cubical and cylindrical. Generally, cube size of 15×15×15 cm 3 is used for testing and the size of the cylindrical is 15 cm diameter and 30 cm height.

Testing in-wall compressive strength

The masonry units are tested in accordance with ASTM C 67 to determine compressive strength. Mortar is analyzed for chemical composition. The masonry strength can be estimated using Tables 1.6.2.1 and 1.6.2.2 in ACI 530-88. The fourth way to test the compressive strength in the wall is to use a flat jack as described in ASTM C 1196-91.
