"Cement block"
Cement blocks are used in construction to build walls and ceilings. The size of the cement block is different. Usually, each block making workshop produces specific sizes according to the customer's needs. But recently, according to the engineering system organization and the national standard, a fixed size and thickness is usually considered for all types of cement blocks. The ingredients of cement block are usually Portland cement, sand, sand, and water by casting method. "Plaster Style Blocks"
There are different types of plaster blocks in the market. Some of these blocks have specific dimensions. In some cases, they have the role of a prefabricated wall. These blocks are in the form of rectangular cubes and have completely smooth and parallel surfaces. It has a crotch and tongue, and these blocks are easily put together during operation. The mortar between them is a special glue that is a mixture of plaster.
This type of blocks can be produced colored by using colored materials according to the requirements of this standard. In order to differentiate the different types of production and use of different types of plaster blocks, they are produced with different colors.
"Ceiling foam blocks"
Ceiling foam blocks or polystyrene is one of the light construction products. Recently, this type of block has been widely welcomed by builders due to its light weight in tall buildings and commercial centers and towers. The weight of polystyrene blocks is usually 15 kg.

"Clay style block"
Clay blocks are also known as clay bricks. The ingredients of this type of block are clay and water. Clay blocks are produced in perforated molds. It is used in non-load-bearing parts of the building.
Clay blocks are produced and used in wall and ceiling types. The surface of the ceiling blocks is grooved. The reason is to increase the adhesion with concrete. These types of blocks are produced in the factory. Its color is uniform. The weight of these blocks is between 3 and 10 cm. Another type of light block is Hablex.
" Hablex Style Block "
Heblex block is a type of porous concrete. 10 cm thickness is used for the inner walls and 15 cm thickness for the surrounding walls. In the market, Heblex light building blocks are available in two types, autoclaved and non-autoclaved. Of course, the non-autoclaved block is cheaper. Therefore, its quality is far lower than the autoclaved block type. High compressive strength and low weight are the advantages of Hablex block.
" block Leica style "
Lika block is another type of style block. In this type of block, Lica seeds are used instead of natural aggregates. Lika grain or industrial pumice is made of expanded clay.
Leica style blocks are one of the most important products of Leica in Iran. These blocks are obtained from a mixture of cement and water. To maintain the lightness of these pieces, the natural grain of the concrete has been removed. The final product has a higher porosity than semi-light concrete.
The spatial weight of light-grained concrete blocks is often less than 1100 kg/m3. The resistance of these blocks is at least 30 kg/cm2. If needed, with a proper mixing design, resistances up to 100 kg/cm2 can be reached.
Lika block is produced in two shapes, solid and hollow, for use in walls and ceilings. The wall thickness of hollow blocks is more than normal cement blocks to take advantage of their insulating properties.
This increase does not have much effect on the final weight of the block due to the very low weight of the concrete used. Lika blocks are produced in different types of peripheral walls and blades.
Lika blocks are widely used in all types of exterior walls, separators, facades, double-walls, insulation, fireproof, and light concrete roofs (beams and blocks).
" mineral style block "
Mineral light block is a type of light block. There is a strong relationship between the cement content of light pumice concrete and its compressive strength. Considering that cement has a higher specific weight than pumice aggregate and water, the resistance increases with increasing density of specific aggregate.
The higher the strength in light pumice concrete, the more cement it will need.
In addition to reducing the weight of the building, light mineral block is also suitable for sound and heat insulation. In many countries of the world, blocks with different dimensions and types are made according to different needs and according to national standards and laws.
