heavy concrete
To make heavy concrete, materials such as steel, cast iron and barium sulfate replace sand in its composition. For this reason, heavy concrete is about 2 times heavier than ordinary concrete. This high weight has made this type of concrete known as heavy concrete among experts. Due to the use of these materials in the construction of this type of concrete, the cost of its construction increases compared to other concretes.
In addition, the amount of energy consumed and the time it takes to make it is more than other types of concrete. For this reason, heavy concretes are more expensive than other concretes.

The density of heavy concrete is usually more than 3200 kg/m3 and on average it is 6400 kg/m3. Of course, this density depends on the amount of aggregate used in making this type of concrete. To mix this type of concrete, various methods are used such as mixing, pre-filled aggregate, pumping and conventional methods.
Features and benefits of heavy concrete
Each of these methods are different in terms of the mixing method and the size of the aggregate used in them. As a result, they make the characteristics of heavy concrete different. The method used to mix concrete ingredients also has an effect on the density or specific gravity of heavy concrete
However, in general, it can be said that heavy concrete has many similarities to ordinary concrete in terms of characteristics. Finally, the use of materials such as steel and cast iron in the structure of this type of concrete can increase their density to about 9000 kg/m3.
Disadvantages of heavy concrete
One of the main disadvantages of heavy concrete is the high cost of its production and construction. Because the use of metal particles in the construction of this type of concrete greatly increases the cost. In addition to metal materials, the aggregates used in the construction of this type of concrete have specific characteristics and standards. For this reason, they are only extracted from certain mines. As a result, the cost of extracting and transporting stones should be added to the cost of producing heavy concrete.
