M.test#6: Compressive Strength Cylinders

M.test#6: Test for compressive strength of cylinders or cubes (AASHTO T 22-92) (ASTM C39)

This test method covers determination of compressive strength of cylindrical concrete specimen such as molded cylinders and cubes . It is limited to concrete having a unit weight in excess of 800 kg/m^3

M.test#3 : test method for unit weight ASTM C138

M.test#3 : Test method For Unit Weight ASTM C 138


This test method covers the weight of concrete per meter cube from air entrained machine
We can find unite weight of concrete by dividing the weight of concrete to volume of machine of machine g/cm*3

M.test#2 Air Entrained ASTM C138

M.test#2 : Test method for Air Entrained ASTM C138

This test method covers determination of the air content of freshly mixed concrete from observation of the change in volume of concrete with change in pressure
