So, if you’re trying to number out how numerous bags the concrete in a yard for your project, this guide is because that you.

You are watching: How many 50 lb bags of concrete in a yard

To mix a garden of 4000psi concrete you’ll require ninety 40lb, seventy-two 50lb, sixty 60lb, forty-five 80lb, or forty 90lb bags the mix. A dry garden of concrete weighs around 3600lbs and needs 32 come 34 gallons that water. A yard of concrete will certainly make a 4” thick, 81ft² slab.

In this guide, we’ll discuss how plenty of square feet space in a yard of concrete, various weights the bagged concrete, cubic feet every bag, the variety of bags that consist of a yard, and how plenty of bags ~ above a pallet. We’ll additionally explain just how to calculation the amount of concrete you’ll need for a slab, fence post, or sonotube, to add what the dry load of a yard runs. This is the ultimate guide for deciding whether ready-mix or bagged concrete is finest for her project.

Sonotube footings because that decks frequently have a deck anchor inserted into the concrete rather of a section of the post, therefore they are fully filled through concrete. Calculate the volume of the sonotube using its radius and also length or depth that is sunk right into the soil (v = π r²h whereby pi or π = 3.14). The table listed below indicates the lot of concrete essential for various diameters the 4-foot sonotube lengths.

 Concrete because that Sonotube Deck Footings Sonotube Diameter Volume 60lb Bag (0.45ft³) 80lb Bag (0.6ft³) 8” x 4ft 1.393ft³ 3.1 or 4 bags(or 3 bags and also a absent or two) 2.32 or 3 bags 10” x 4ft 2.181ft³ 4.84 or 5 bags 3.635 or 4 bags 12” x 4ft 3.14ft³ 6.98 or 7 bags 5.23 or 6 bags

## How much Does a garden of Concrete Weigh

A yard of concrete is written of cement, sand, and stone or gravel, otherwise known as aggregates. The dry contents is bagged and also shipped on pallets. Different grades or staminas use different ratios in the blend, resulting in varying weights every yard. The weight of water included is about fifty percent the weight of the cement ratio in the mix.

It takes sixty 60lb or forty-five 80lb bags the 4000psi concrete mix to make a yard of concrete. Mathematically, 60×60 = 3600lbs and also 45×80 = 3600lbs, therefore a dry cubic garden of concrete mix would certainly weigh 3600lbs. Adding water to the mix increases the median weight to about 4000lbs.

Depending on the manufacturer, the proportion of measures to make the concrete mix, elevations, and also temperatures, a garden of concrete may need in between 27 and also 35 (or more) US-gallons of water. A united state gallon that water weighs 8.34lbs, therefore the variety of gallons increases the weight accordingly.

Water is necessary for the chemistry reaction come harden the powder mix. However, although that doesn’t change the in its entirety finished volume much, it does readjust the early weight. As the concrete cures, lot of the water evaporates, reducing the weight to approximately 3700lbs.

## How numerous Yards that Concrete in a Truck

The lot of load a van can bring depends top top what that is designed to carry. Some determinants affecting loads are where it is traveling and also when. Hills and bridges have the right to restrict pack sizes, and weight restrictions may vary between jurisdictions and also even seasonally. Additionally, statutory united state weight boundaries of 80,000 pounds ~ above tractor-trailers restrict lots to between 43,000 and also 47,000 pounds, as carry out 48,000 pounds ~ above 3-axle cement trucks.

On typical most ready-mix concrete trucks lug 10.5 yards or 42,000 pounds, return some bring 12.5 yards. A 48’ tractor-trailer often carries 14 yards, shipment trucks 2 to 3 yards, and a half-ton truck around a 3rd of a garden of dry mix.

To recognize your vehicle’s delivering capacity, determine the GVWR and also subtract its curb weight. A 1/2-ton truck with a 6600lb GVWR and a curb weight of 5100lbs, has a fill capacity the 1500lbs, consisting of the driver, passengers, and also cargo. It no recommended to exceed the fill capacity.
