Experimental results are presented which show the effects of cement content, air content, slump, aggregate grading and specific gravities on the unit weight of fresh and hardened concrete. With a knowledge of these effects an intelligent and resolute selection of the different proportions for a specified concrete density can be made.

• #### Quick Answer: How To Calculate Unit Weight Of Concrete ...

How do you calculate weight of concrete in kg? A typical concrete mix weighs 150 lbs per cubic foot, 4,050 lbs per cubic yard, or 2,400 kg per cubic meter. The weight of concrete is determined by its density, which can vary based on the amount of aggregate, water, and air in the mix. Determine the Density of Concrete.
