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
