At this point, concrete has achieved about 99% of its strength, and will continue to very slowly strengthen over the next few years. At 28 days old, I use a density of .085 pounds per cubic inch (146.9 pounds per cubic foot) when calculating structural load. Concrete is porous.
A cubic yard of concrete's average weight is 4,050 lbs, or 150 lbs per cubic foot. Quikrete concrete bags come in 40lb, 50lb, 60lb, & 80 lb.
How many bags of concrete per m3? You will require approximately 100 - 110 x 20kg Concrete Mix bags per m3 of concrete you need. The guidance varies slightly depending on the brand. For example, looking at the popular concrete mix available at Bunnings, we see the following: Bastion 20kg Concrete Mix: 100 x 20kg Bags per cubic metre XMJJP.
