weight and dimensions - characteristics + Photo and Video Silicate one-and-a-half brick: weight and dimensions. Today the most popular building element is one-and-a-half silicate brick.

It is often used for the construction of load-bearing surfaces and partitions in houses.

The popularity of this material is due to the fact that work with it is performed efficiently, quickly and, which is important - economically.

General information

Technical characteristics and properties

This building material is obtained by pressing a special mixture in an actoclav, which includes water, quartz sand, modifiers and lime.

Silicate bricks have decent performance characteristics.

  1. Thermal conductivity of sand-lime one-and-a-half brick is 0.56W / mOs. This indicator is much less when compared with red ceramic material, therefore, for expediency, it is better to build external walls from this brick.
  2. weight and dimensions - characteristics + Photo and Video Density to irpich.

    Elements that are solid are much stronger than hollow ones. When comparing the indicators, the density of a full-bodied element is 600 units higher than the second.

  3. Moisture absorption . This indicator is very important during construction. The crystalline structure of the material makes it possible to quickly absorb and release moisture.

    For this reason, you do not have to worry about cracks appearing on the walls that are made of this material.

  4. Flexural and compressive strength . The most popular brand is number 150, as its strength index is 50kg / cm 2.
  5. Resistance to freezing and thawing up to about 35 cycles.
  6. The best option for the construction of partitions between rooms, as a silicate one-and-a-half brick has high sound insulation.

  7. The size of one-and-a-half silicate brick is 250 * 120 * 88 mm.
  8. The weight of the element is approximately 4 kg.

Please note, that experts strongly do not recommend building a foundation and basement floors from silicate bricks, since groundwater contains a higher percentage of sulfuric acid, which is capable of decomposing silicates ...

Advantages of silicate bricks

In the construction of floors and walls, hollow bricks with thickening are usually used. In this case, the voids are blind and through. In shape, they can resemble a cylinder, which is located perpendicular to the base. Due to these cells, the brick becomes lightweight, which reduces the load on the foundation. Another plus in this situation is that the performance and sound insulation characteristics are improved many times over.

When all of the above are analyzed, the following advantages become apparent:

  1. Saving time when laying. The partition, which is the carrier, is laid in 2 rows + 1 additional row of cladding.
  2. Huge savings in binder mortar.
  3. The service life of a silicate brick building is increased.
  4. The index of heat preservation and frost resistance of walls increases.

Facing one and a half brick can be in several colors: red, pink, blue and yellow. Such shades became possible to obtain thanks to pigments that are added to the mixture and which are resistant to alkali. They are added at the production stage. Besides the fact that the walls can be made presentable, they allow the walls to "breathe", and this also prolongs the service life.

Features, dimensions and weight of one-and-a-half silicate bricks

Dimensions (weight and size) of one silicate brick exceed those of a ceramic analog several times.

This is due to the fact that lime and quartz sand, which is the basis, makes it quite heavy. The components that are taken in the production of this building material have a high level of hygroscopicity, which also affects the weight of the brick.

If you use silicate brick for the construction of walls, then it is divided into the following 2 groups: ordinary and front. But the size of the brick does not depend on its type. The standard size, as we said, is 250 * 120 * 88 mm.

The cladding stone is smooth and has a fairly beautiful surface. It has a perfect look for beautiful styling.

But an ordinary one-and-a-half silicate brick is used for slightly different purposes. Usually it is made only in white and is used for walls and partitions. In such works, the smoothness of the brick is not important, it is much more necessary for the brick to be strong and dense in structure.

The mass index of the material in this case depends only on the structure. Solid bricks are dense, solid mass without holes and voids. In this case, the maximum weight of one-and-a-half sand-lime brick will be 4.5 kg.

Hollow stones from the inside look like a combination of cells, holes and voids.

Weight will depend on the quantity, but the average does not exceed 4 kg.

Popular questions

Why know the mass of a brick?

The weight of any geometric body can be easily calculate by the formula - multiply the density of the body by the volume (m = p * V). These indicators are easy to find yourself. When calculating, take into account the humidity indicator, the presence and number of voids in the brick, as well as the presence of decorative finishes. Weight indicators may differ slightly from each other, but this depends on the concentration of moisture in the brick.

A large percentage will increase the weight of the item. The presence of voids and cells, on the contrary, will reduce the brick mass indicator.

In practice, the specific gravity of an element is in the range from 1300 to 1900 kg / m 2 . Knowing the formula for calculating one element, it will be easy to calculate how much pressure will be on the foundation.

If you made the calculation, and it turned out to be correct, you can save money and not equip the basement.

The house will be strong, and the walls will not crack just due to the fact that calculation errors were made during the construction. Manufacturers of silicate one-and-a-half bricks and sellers always indicate the exact dimensions and weight of the product, which makes the counting process easier.

Where is it used?

weight and dimensions - characteristics + Photo and Video This material became popular thanks to assortment: the colors of the surface of the edges are varied, the bricks are produced both solid and hollow, and this allows the architect to approach the creation and creation of the project creatively, in order to obtain a masterpiece of architecture as a result

This building material is actively used for laying external and internal walls. If you connect one and a half, single, white and multi-colored bricks together, you can get a chic building finish.

Experts in this business have identified some factors in which one-and-a-half silicate brick is better not to be used in construction.

In practice, this is due to the climatic conditions and the operation of the house, as well as the design features of a technical nature.

When a silicate brick is exposed to a temperature of more than 600 degrees, the tensile strength becomes several times lower, and cracks begin to appear. This stone cannot be used to install fireplaces, chimneys and stoves. For this type of work, only refractory materials should be used.

Attention! Sand-lime bricks can only be transported on pallets.

This makes it possible to save the material, and properly organize the process of laying the walls.


So, as practice shows, silicate one-and-a-half brick is a building material with excellent operational and technical characteristics. It is usually used for the construction of partitions, floors and walls in the house. An important advantage of using this material is cost. It is small, and this will help reduce construction costs.
