The density of concrete varies, but is about 150 lb/cu ft.
mass = density x volume = 140 cu ft x 150 lb/cu ft = 21000 lb
1 lb ≈ 0.454 kg
→ 21000 lb ≈ 21000 x 0.454 kg ≈ 9525 kg (= 9.525 tonnes)
Lightweight concrete typically weighs between 90-115 pounds per cubic foot, which is significantly less than standard concrete that weighs around 140-150 pounds per cubic foot. The lower weight of lightweight concrete is achieved by incorporating lightweight aggregate materials, such as expanded clay, shale, or slate.
The density of one cubic foot of concrete typically ranges from about 140 to 150 pounds, depending on the mix and specific materials used. This translates to approximately 2,240 to 2,400 kilograms per cubic meter. Variations can occur based on factors such as the type of aggregates and additives used in the concrete mix.
The weight of concrete typically ranges from 140 to 150 pounds per cubic foot. To determine the weight per square foot, you must consider the thickness of the concrete slab. For example, a standard 4-inch thick slab of concrete weighs approximately 40 to 50 pounds per square foot, as there are 3 inches in a quarter of a foot.
Normal concrete has a density around 2400 kg/cubic meter or 4048 lb/cubic yard. There are many different kinds of concrete, many of which are much lighter. Cement is the liquid (or paste like) form, and tends to be much heavier than when it has cured into concrete. "Cement" is not concrete, but can be used to make concrete by mixing with sand, stone and water. The density of cement is about 3120kg/m3.

Oh, dude, a cubic foot of grout typically weighs around 140 pounds. So, like, if you ever need to carry that much grout around, maybe hit the gym first or just hire someone else to do it for you. Remember, lifting heavy stuff isn't for everyone... or anyone, really.
140 (cubic meters) = 4,944.05 cubic feet.
Typically a ready mix concrete weighs anywhere from 135 lbs to 160 lbs per cubic foot. The weight varies widely due to the different densities of the aggregates that are used in concrete mixes. Lightweight aggregates such as expanded shale can be used to significantly reduce weight but there is some sacrifice in strength taking this approach. Typically the denser the concrete and aggregates the higher the strength and weight.
(2/3)*10*7 = 140/3 = 46.66... cubic feet.
The Density of normal concrete is assume 150 Lbs/Cft Here i describe the detail to find. The normal concrete has a density of 2400kg/m3, and to convert this in Punds per cubic meter, we can divide the 2400 with 35.31 (1 Cubic meer = 35.31 cubic foor) the answer is 67.97 KG/Cft (2400/35.31=67.97). then multiply this with 2.204 (1 KG = 2.204 Lbs) so the answer is 149.80 Lbs/Cft.
140 cubic decimeters is 1400dL
PCC stands for Portland cement concrete, and its unit weight typically ranges from 140 to 160 pounds per cubic foot. The specific weight can vary based on factors like the mix design, aggregate content, and compaction level.
