# How many bags of concrete to fill a 55 gallon drum?

The article aims to answer the question “**How many bags of concrete to fill a 55 gallon drum?”.** It will also discuss how much a gallon of concrete weighs.

Read on to know how to estimate the calculations related to the weight of concrete weight.

## How many bags of concrete to fill a 55 gallon drum?

The number of bags of concrete you need to fill a 55 gallon drum depends on the size of bag you are using. For instance, if you are using 60 lb bags, you need 16 bags of concrete to fill a 55 gallon drum, and if you are using 80 lb bag of concrete, you need 12 bags of concrete to fill a 55 gallon drum.

## How much does 1 gallon of concrete weigh?

A gallon of concrete weighs around 20 pounds (or 0.01 tonnes), and has a volume of about 0.133 cubic feet (or 0.0049 cubic yards) when mixed. To determine the weight of concrete at a construction site, this estimate is employed.

## How much does 55 gallons of concrete weigh?

55 gallons of concrete weighs roughly 550 pounds. Depending on the ingredients, you could gain or lose up to 200 pounds. The basic calculations are;

- The weight of one gallon is equal to 20.08 pounds.

- 5 gallons = 5 x 20.08 = 100.40 pounds

- 453.59 grammes is equal to one pound

- This concludes our discussion.

- It weighs 550 lb per 55 gallon.

## How much does concrete weigh?

The amount of air and water it contains may affect the weight of concrete. The importance of cement may range from 830 to 1650 kilograms per cubic meter, equivalent to 52 to 103 pounds per cubic foot.

Denser cement is obtained by storing and transporting cement subjected to vibration, as opposed to glue placed into silos pneumatically. Consider that a 94 lb. a bag of newly packed cement equals one cubic foot when weighed.

Lightweight concrete density is 1920 kg per cubic meter (116 lbs per cubic foot) or 116 kilograms per cubic meter (3132 lbs per cubic yard). It weighs less because it is created of pumice, an inherently light mineral.

It is a mass to volume ratio that determines density. The simplest and most accurate method for determining the density of concrete is to fill a specified volume container and weigh it.

Checking concrete strength using test cylinders benefits knowing, comprehending, and monitoring density. In most cases, a decrease in concrete density results in a reduction of concrete strength.

These strength tests may be performed every 24 hours, seven days, and 28 days in a laboratory to detect potential weakness (or lower density). This is critical because concrete is utilized in so many high-strength structures (bridges and high-rises).

In the case of concrete countertops or inside radiant floor heating, you may question whether utilizing lightweight concrete will reduce stress on cabinets and flooring below.

It weighs roughly 18 pounds per square foot for conventional weight concrete and about 14.5 lbs per square foot for lightweight concrete.

Even though concrete countertops weigh less than regular concrete, it’s still simpler to polish standard density concrete because of the 3.5 pounds per square foot weight savings.

Using a vast concrete area for flooring might save a significant amount of weight. Keep in mind that the cost of lightweight concrete is generally twice as much as that of ordinary concrete.

## How can I calculate the weight of a square foot of concrete?

You may use the following formula to get its weight in pounds per square foot if you know how thick your concrete is.

**CEMENT WEIGHS 145 POUNDS FOR A CUBIC FOOT.**

- Take the thickness of your concrete and divide it by 12. (this gives you the depth in feet.)

- As an illustration: Dividing six by twelve gives you five percent (a 6-inch slab is .5 feet thick)

- One hundred forty-five pounds per cubic foot x.5 = 72.5 pounds per cubic foot or 72.5 pounds per cubic meter.

- A 6-inch thick slab weighs 72.5 pounds per square foot, the maximum allowable weight.

- Do you know the weight of a 4-inch-thick slab of concrete?

- The weight per square foot is 47.85 pounds when divided by the number of decimal places in the formula (4/12).

## Conclusion

Several variables affect the density of concrete, including the quantity of water and air in the mix. To put it another way, a block of concrete that is one foot wide, one foot long, and one foot high would typically weigh 150 pounds when measured in pounds per cubic foot (lb/ft3).

Assuming that a cubic foot of concrete weighs 2400 kilograms per cubic foot, a block of concrete that is one meter wide, one-meter long, and 1-meter high would weigh 2400 kilograms.

A gallon of concrete weighs around 20 pounds (or 0.01 tonnes), and has a volume of about 0.133 cubic feet (or 0.0049 cubic yards) when mixed. To determine the weight of concrete at a construction site, this estimate is employed.

The number of bags of concrete you need to fill a 55 gallon drum depends on the size of bag you are using. For instance, if you are using 60 lb bags, you need 16 bags of concrete to fill a 55 gallon drum, and if you are using 80 lb bag of concrete, you need 12 bags of concrete to fill a 55 gallon drum.

## When cured, does concrete get heavier?

As the cement hardens, the quantity of water that interacted with the cement is reflected in the cement’s weight difference from when it was fresh. A bag of hardened cement will always be heavier than a fresh bag because of this.

## Concrete or sand is heavier?

Almost usually, water at its densest is used as a benchmark for liquids! In comparison, the density of sand ranges from 2.65 to 2.67. Cement is heavier than sand in terms of scientific weight!

## How much weight can a four-inch thick concrete slab withstand?

On an uncertain 4-inch slab, we typically restrict the weight to roughly 40 lb/sq ft. 80 pounds per square foot may be possible in certain circumstances, but unless you have an idea of the slab’s bearing and reinforcing capacity, you run the risk of breaking.
