Concrete type, volume, and truck payload planning
Concrete Weight Calculator
How much does concrete weigh per cubic yard? Normal concrete weighs 3,700–4,050 lb/yd³ (about 2 tons). Lightweight mix: 2,360–3,120 lb/yd³. High-density: up to 6,740 lb/yd³. Enter volume to get lbs, kg, and tons — with truck payload and haul-load checks.
1 cubic foot of concrete
145–150 lb (standard mix)
Normal concrete weighs 145–150 lb per cubic foot. Lightweight concrete: 95–115 lb/ft³. Heavyweight: 180–220 lb/ft³.
1 gallon of concrete
about 20 lb
1 gallon = 0.134 ft³. At 150 lb/ft³, 1 gallon of wet concrete weighs about 20 lb. A 5-gallon bucket holds roughly 100 lb of concrete.
10 ft x 10 ft x 4 in slab
about 5,000 lb at 150 lb/ft3
That is 50 lb per square foot and about 2.5 short tons before entered steel weight.
1 cubic yard
about 4,050 lb at 150 lb/ft3
Use the supplier or project density when the exact mix, moisture, or specialty aggregate matters.

What to know about concrete weight before you order
Most weight questions come from a real decision: Can my truck handle this? How many loads? What does disposal cost by ton? The numbers below are what concrete weight calculators usually skip.
| Benchmark says | Replace with local input | Next check |
|---|---|---|
| One fixed concrete density | Keep density visible and editable. Normal-weight planning values are not a substitute for the actual mix, moisture condition, aggregate, or project documents. | Ask which density the supplier, engineer, hauler, recycler, or scale-ticket estimate uses. |
| Weight equals safe payload | Compare with a payload capacity entered from the specific vehicle, trailer, container, route, or provider instead of using a generic recommendation. | Confirm legal payload, axle limits, container rules, loading method, access, and final scale-ticket billing. |
| Concrete-only weight is the whole load | Add a known steel or embedded-item weight, then keep soil, moisture, asphalt, mixed debris, equipment, pallets, and container tare outside the result. | State inclusions and overweight responsibility in the demolition, hauling, or disposal quote. |
Concrete weight and delivery planning checklist
Use these checks before relying on the result for removal, transport, disposal, lifting, or structural work.
| Signal to check | What it means | Next step |
|---|---|---|
| Dimensions and thickness | The measured slab sections, thickened edges, footings, toppings, columns, and quantity match what is being moved or removed. | Measure separate sections instead of hiding every thickness inside one average. |
| Density assumption | The selected lb/ft3 or kg/m3 value matches the intended planning source and concrete type. | Use project-specific data when the result affects a lift, structure, freight plan, or contractual limit. |
| Whole load | Steel, soil, moisture, coatings, asphalt, mixed debris, pallets, tools, container tare, and equipment are included or explicitly excluded. | Do not compare concrete-only weight with a whole-vehicle or whole-container limit. |
| Payload and disposal rule | The provider confirms allowed material, included weight, maximum payload, fill line, overage rate, and rejected-load policy. | Replace the planning inputs with the written provider limits before scheduling. |
| Professional boundary | The calculator has not been used to approve structural capacity, crane picks, rigging, vehicle loading, axle compliance, or road access. | Use qualified engineering, lifting, transport, and local regulatory review where required. |

How much does a cubic yard of concrete weigh?
A cubic yard of normal-weight concrete weighs 3,700–4,050 pounds (about 1.85–2.03 tons). The exact weight depends on the mix design and aggregate type. At 150 lb/ft³ density, one cubic yard (27 ft³) works out to about 4,050 lb. Lightweight mixes (pumice, perlite aggregate) weigh 2,360–3,120 lb/yd³. High-density concrete used in radiation shielding can reach 4,720–6,740 lb/yd³.
How much does concrete weigh per cubic foot?
Normal-weight concrete weighs about 145–150 lb per cubic foot (2,320–2,400 kg/m³). Lightweight concrete runs 90–115 lb/ft³. High-density concrete can reach 180–250 lb/ft³. The 150 lb/ft³ figure is the standard design assumption used in structural engineering for normal-weight concrete.
How much does a full concrete truck weigh?
A standard concrete mixer truck (transit mixer) weighs 25,000–30,000 lb empty. With a full 10-yard load of concrete (~40,500 lb of concrete), the gross vehicle weight reaches 65,000–70,000 lb. Most highways limit trucks to 80,000 lb gross. This is why trucks often deliver partial loads to stay under weight limits, especially on residential streets rated lower.
How many tons is a yard of concrete?
One cubic yard of normal-weight concrete weighs approximately 2 tons (4,050 lb ÷ 2,000 lb/ton = 2.025 tons). Lightweight concrete runs about 1.2–1.6 tons per yard. These numbers are important when planning haul loads, dumpster rentals, or checking truck payload ratings — most flatbed and dump trucks are rated for 5–10 tons payload.
Does wet concrete weigh more than dry concrete?
Yes — wet (freshly mixed) concrete is heavier. Wet concrete weighs about 150 lb/ft³ (4,050 lb/yd³) because it contains the full water content. After curing, some water evaporates and the concrete may lose 5–10% of its weight, settling around 135–145 lb/ft³ depending on the mix and curing conditions. For structural design, engineers use the wet weight since concrete is poured and bears load before it cures.

This calculator provides planning estimates from dimensions, density, and user-entered capacity or rates. It does not approve structural loads, lifting plans, rigging, vehicles, trailers, dumpsters, axle weights, routes, road access, disposal acceptance, or legal payload. Confirm actual density, whole-load weight, provider limits, scale tickets, and required professional or regulatory review.
