What Is 1.54 In Concrete Calculation? - [Civil Planets]

Wet Volume of concrete = Dry Volume of concrete + 54% of the dry volume of concrete or. Wet Volume of concrete = Dry Volume of concrete x 1.54. So whatever volume we get from the above formula, we need to multiply the value with 1.54%. So to get 1 m3 of wet concrete, we have to multiply the dry volume by 1.54. Consider M20 Mix Ratio ( 1 : 1.5 : 3)
