Hollow brick in construction

Our country mostly lies in those latitudes that provide significant changes in the annual temperature - from frost phenomena to drying up heat. In this sense, people have to thicken the walls in order to improve the comfort (thermal insulation) of the dwelling. However, thick walls can exert a noticeable pressure on the foundation. The question is how to solve this problem. The answer can give a special brick, hollow and durable.

This material is much easier and easier to handle than simple building materials. A hollow ceramic brick makes it possible to erect walls that are thinner, while retaining the properties of absorption of noise and heat. In addition, the overlapping of it does not lose in strength, as in the case of solid brick. The use of such a brick in construction is convenient and profitable for two reasons. First, the cost of material is reduced by saving raw materials and energy resources, and secondly, construction will require less material.

Bricks are made of clay. From other building materials it is distinguished by the presence of holes of various shapes, sizes and quantities. Slots can be either through, or simple grooves. Round and oval hole shapes greatly reduce the likelihood of undesirable cracking during brick making. The resulting volume of air in the product increases the thermal insulation properties of the material. It is important that the solution is thick enough and does not fill the gap, thus displacing the air from the cavities. This will reduce the efficiency of brick use. The maximum amount of slits in relation to the whole figure can reach 50%, but the average indicator is within 36%. This percentage of voids will achieve the best performance properties of the brick.

Of the existing products on the market - brick ceramic hollow and full-bodied - each has its inherent advantages and disadvantages. For example, the solid volume of the figure allows it to be used for laying the foundation, the bearing parts of the building, where the hollow version is forbidden to use because of the high probability of freezing, rupture and fracture into parts. Also, it is not advisable to use a hollow brick for the construction of furnaces - due to the constant temperature changes and frequent overheating of the material, its integrity is violated. Solid brick, on the contrary, accumulates heat due to its mass. Such properties will be combined as a base and facing - full-body accumulates heat, and hollow - retains.

Effective use of brick hollow finds in the construction of small residential premises. In case of erection of uninhabited and, accordingly, unheated buildings, it will be more expedient to give preference to a different type of brick. A hollow version will have to come in handy for building internal walls and partitions. Based on the strength properties, a brick with holes is produced under the following brands: M-75, M-100, M-125, M-150, M-200.
