How Much Does Concrete Weigh

Quick answer

How Much Does Concrete Weigh: normal-weight concrete is about 150 lb per cubic foot, 4,050 lb per cubic yard, and roughly 2,400 kg per cubic metre. A 4 inch slab is about 50 lb/ft² before anyone walks on it.

How Much Does Concrete Weigh: Lightweight and rebar

Lightweight mixes can land near 110 lb/ft³. Concrete Calculator’s 156 lb/ft³ option is a small planning bump for rebar — not a bar schedule. Real rebar weight comes from the shop drawings.

How Much Does Concrete Weigh: Why it matters

Pickup trucks are not mixers. Elevated decks need a structural dead load. Full ready-mix trucks haul on the order of 20 tons of concrete plus the vehicle. Crushed concrete as fill uses gravel-style densities — see tons and cubic yards.

Do it in Concrete Calculator

Open the weight calculator, enter the pour, and pick a density. Kilograms appear beside pounds for metric tickets.

Rules of thumb worth keeping

150 lb/ft³ · 4,050 lb/yd³ · ~2.0 short tons/yd³ · ~50 lb/ft² at 4 inches · ~75 lb/ft² at 6 inches. Lightweight mixes break the first line — switch density. Reinforcing steel adds a little; Concrete Calculator’s 156 option is a nudge, not a bar list.

How much does 1 yard of concrete weigh? About 4,050 lb. How much does a yard of crushed concrete weigh? Different material — use gravel factors near 1.4 ton/yd³ on the gravel tool.

Pickup trucks and trailers

Half a yard is about a ton. That is already past many consumer pickup ratings once you count the bed and passengers. Trailers and dump trucks exist for a reason. If you must move bagged mix, move bags — not a wet yard.

Field notes to keep handy

Measure to the outside of the forms. Convert every side to the same unit before you multiply. Apply waste after you sum every piece of the job, then round once for the plant.

Bag counts always round up because a partial bag is still a whole bag at the store. Compare that total with a delivered price when short-load fees show up on the quote.

Normal-weight planning density here is 150 pounds per cubic foot unless you switch it. Lightweight mixes and specialty bags can differ — read the ticket or the label when they do.
