How Much Does Concrete Weigh

How Much Does Concrete Weigh? (With 10 specific examples)

Concrete is a mixture of cement, water, aggregates and sometimes slag or flies ash-type additional materials. You can use concrete to create an essential part of the construction sites. It’s one of the most universal building materials around the world. 

The weight of the concrete is determined by its density depending on the concrete mixture. It increases or decreases a little and depends on the cement, water, aggregate and air used to create the mixture.

In this article, we’ll discuss all about how much does concrete weighs. We will also talk about the biggest concrete structure in the world.

Determine The Density Of Concrete:Density Of Concrete

As we mentioned before, concrete is a mixture of different types of materials. Such as cement, water, aggregates, and sometimes slag or fly ash like materials.

The weight of components depends on various factors. For example, the density and amount of the aggregate, the amount of entrapped air, and the cement and water content. The density is the measure of concrete component weight. 

The density of concrete is determined by mass and volume as shown in the below formula:

Density (p) = mass (m) ÷ Volume (V)

A typical density of concrete is 3.15 g/cm3 where the density of aggregate will differ by the type of stone used. For example, gravel has a higher density than vermiculite. The density of a common concrete mix is (2.4 g/cm3 or )150 lbs/ft3.

The best concrete mix for a countertop has less aggregate when compared with the mix for a driveway. These will affect the density and then the weight of the concrete.

Density of Concrete

Volume                   Weight

1 in3                 1.39 oz

1 ft3                 150 lb

1 yd3               4050 lb

1 m3               2400 kg

How Much Does Concrete Weigh? 

The weight of concrete is measured by its density, which can differ from the amount of aggregate, air and water in the mix. Concrete is made of these materials, so the weight variation occurs when there is any variation in ingredients. However, this weight can differ from different types of concrete, but they are not far from each other.

There is a straightforward answer to this common question. On average, regular concrete mix weighs 150 pounds per cubic foot, 4,050 pounds per cubic yard, or 2,400 kg per cubic meter.

Wet Vs Dry Concrete: How Much The Weight Difference?Wet Vs Dry Concrete

Concrete is a mixture of cement, aggregates, sand and, eventually, water. The water makes a specific chemical reaction with all of the items together. Water is important to create the concrete, which takes a part of the included weight. 

But, always remember that your finishing result is almost similar to the given amount. It’s going to be because of the evaporation of the water. As a result, both wet and dry concrete have individual weights, but they are not much different. The amount of concrete you get is not going to change much more.

Weight Variation?

Different types of concrete have different weights. It can be cement, gravel, Portland, reinforced, and lightweight. Lightweight concrete is usually made of pumice types of light density material. 

The regular weight of lightweight concrete is 1920 kg per cubic meter or 116 pounds per cubic foot (3132 pounds per cubic yard) on average. Always remember that the price of the lightweight concrete is double than the regular concrete but it’s weaker than regular concrete. This is because of the higher water content present in the lightweight concrete.

Factors In The Weight Of Concrete

Concrete is a man-made multicomponent complex material. All of the components contribute to the overall weight of concrete. That means concrete has a different range of weights. Some concrete is dense where the others are light. Many one of them is mixed with heavy aggregates, and the other is mixed with fine sand. These factors will affect how much concrete weighs. Again, most of the weight comes from the cement and aggregates.

10 Specific Examples of Concrete 

If you have less interest in the math behind the weight of concrete but more interest in specific examples this section is for you. We think it will be interesting to know exactly how much concrete megastructures weigh. So we made a list of ten specific examples of how much concrete weighs.

Identical Concrete Towers 

Petronas Twin Towers are twin buildings in Kuala Lumpur, Malaysia. It’s an excellent example of F.R. Khan’s invented tube in tube design. This 1,483 feet tower held the world’s tallest building title when it was built in 1998. Once these two identical towers were the tallest skyscrapers in the world.

The tower designed to reflection of Islamic art of Malaysia’s Muslim religion. It was mainly constructed with reinforced concrete with steel and glass. 

Around 144,309,356,753.51 pounds of concrete needed to build these towers. Most of this heavyweight can be placed to it’s 120-foot deep concrete foundation.

  1. Gotthard Base Tunnel, Switzerland

Longest Concrete Tunnel

The Gotthard Base Tunnel is the longest concrete railway tunnel through the Alps in Switzerland. It’s 57.09 km route is the longest railway tunnel in the world. This tunnel is a part of the longest environmental protection projects in Europe. LafargeHolcim provided 1.3 million m3 of concrete for several sections of the tunnel.

In the last few months, freight trains passed the tunnel on average 1080 tonnes in weight. However, the maximum weight capacity will increase from 1600 to 2000 tonnes. 

  1. Polavaram Dam Project, India

Largest Concrete Pour 

Navayuga Engineering Company Limited accomplished the project at  Polavaram Dam Project in Andhra Pradesh, India. The is the largest continuous pour of 32,315.5 m³ (1,141,211.1 ft³). This record project took place at the dam site of Polavaram. Once finished, the dam will be the source of 20 million people’s water supply. The attempts to provide irrigation and electricity to the area. 

  1. Colosseum, Rome, Italy 

Romans Concrete Structure

The last structure we’ll be peeking at is the famous ancient Romans concrete structure. The oval amphitheatre Colosseum is the largest ancient amphitheatre ever built and remains despite its age. It’s located in Rome, Italy, is one of the world’s most famous ancient Roman structures.

Romans Colosseum is one of the earliest buildings, though it is two thousand years old. That time roman was invented concrete and it was their best building technology. So, the Colosseum was made with concrete and weighs a rough 24 tons (48,000 pounds). 

This seems incorrect, but the wood brick was the primary frame of the Colosseum. So, the total weight wasn’t calculated for the solid concrete.

Conclusion:

Concrete is a mixture of cement, water, aggregates and sometimes slag or fly ash like materials. The weight of the concrete is determined by its density which depends on all of these materials. On average, regular concrete mix weighs 150 pounds per cubic foot, 4,050 pounds per cubic yard, or 2,400 kg per cubic meter. This weight can differ from different types of concrete, but they are not far from each other.
