Dimensions and weight of a standard one-and-a-half sand-lime brick

Silicate bricks are made from quartz raw materials, into which lime and other substances are added, which improves the performance of the product. Initially, the brick is given the desired shape using a press according to standard dimensions, and then the workpiece is transferred to an autoclave, where it is subjected to a pressure of 12 atmospheres. After that, the brick is processed with steam at a temperature of 200 degrees. The quality of the finished product depends on the correct execution of these technological processes, and therefore it is important to monitor compliance with the parameters at each stage of production. The technological process averages 18 hours.

The average weight of one silicate is 3-4 kg. Solid brick is used for the construction of buildings no more than 3 stories high. The density of each silicate brick is 1900 kg / cu. m. Also, the manufacturer can produce hollow stones, which have a lighter weight and lower density compared to conventional ones. This makes it possible to reduce the pressure on the foundation and improve the thermal insulation of the room, which allows you to preserve the thermal insulation qualities of the wall and reduce the degree of freezing of the structure with a smaller thickness.

In terms of its severity, silicate is similar to fireclay brick. Some manufacturers may add iron oxide to the raw materials for brick making, as a result of which the product will look like ordinary red brick. But when choosing, you need to be careful, since this type of stones cannot be used to decorate fireplaces or stoves. With intense heating, they will crumble and turn into powder.

It is also important to know the weight of the brick, which is determined by the type of product. Depending on the use, silicate can be as follows.

• Ordinary. It is used for simple masonry and has rough sides. The presence of small chips on the surface is allowed.

• Facing. A decorative product that has a smooth and embossed surface and is distinguished by a large number of colors. The bricks should not have chips or stains on the front sides.

The weight of any body can be calculated in a certain form and perform such work independently. Also, when calculating, it is important to take into account the presence of voids in the product and its moisture content, which affects the weight characteristics. The specific gravity of standard silicate is 1300-1900 kg per cubic meter. Correctly made preliminary calculations will make it possible to find out how much weight will affect the basement and provide a reliable foundation that will withstand all loads and at the same time will not allow the walls to crack during construction. Also, the manufacturer must always indicate the specific gravity of the finished product, which simplifies the calculations.

The strength of the stone is determined by the brand, which must also be taken into account when choosing. For example, grade M75 is used for the construction of structures with a height of no more than one floor. It is also assumed the possibility of constructing load-bearing walls from them with a small load. The M100 brand is suitable for constructions of objects with two or three floors. For tall buildings, a brick with a strength of M200 is used.

Distinguishes any silicate brick fire safety, which is ensured by the absence of flammable components in it. Walls made of this material should, in any case, be additionally finished with insulation. A disadvantage of silicate is a high rate of water absorption.

To know the weight of 1 cube of brick in the masonry, you must initially determine the number of products in it. Experts note that in the cube of masonry there are 414 single pieces, and thickened - 314. This amount is approximately, since it all depends on the thickness of the seams and the type of masonry. For example, the average joint width is one and a half cm, and therefore this value must be added when calculating the number of bricks in one cubic meter of masonry. All the data on which the calculations are made apply only to products manufactured in accordance with GOST.

• The formula for calculating the number of bricks in a cube of masonry: 100x100x 65 (88, 206).
• The formula for calculating the weight in a cube of masonry: 414 pcs. x 3-4 kg.

The bricks to the site are usually delivered in stacked pallets containing one cube of brick. This allows developers to navigate the calculations and order the required number of products. The sizes of silicate are standardized so that it is convenient to calculate their volume and number of units.

These bricks can be used for load-bearing foundations, columns, pillars and other objects, and therefore, before buying, you need to decide on the type of masonry that will be used. The choice of the product in terms of thickness and other parameters depends on this. For example, a single brick is usually used for the construction of load-bearing walls in structures. To fill the voids, you can use one and a half bricks.

Also, when choosing this material, one must take into account the ability to absorb water by it, which reduces characteristics and reduces resistance to low temperatures. Therefore, it is not recommended to use such products without additional waterproofing in basements or other places where high humidity is observed. It must be remembered that silicate does not tolerate high temperatures well, and therefore it is not recommended to use it near heating devices.

Silicate building stones are made rectangular and have standard dimensions:

• single - 250x120x65 mm;
• one and a half - 250x120x88 mm;
• double - 130x176x206 mm.

According to GOST, a deviation from the dimensions by no more than 5 mm is allowed. You should also take into account the presence of a marriage in the party. Non-standard products can also be used for rough masonry or for the construction of partitions.

In practice, it is often necessary to use larger bricks, and therefore in this case it is better to use one-and-a-half bars, in which the width and length remain the same as the standard one, but the height is greater. This thick brick is used depending on the required surface qualities and its voidness. But when laying, it must be remembered that the weight of such a product will be greater. It is often used to speed up masonry, but it is inconvenient to work with it, since you have to lift more weight.

Sand lime brick is an ecological material and has good characteristics, which allows it to be used everywhere. When buying any silicate product, you need to immediately determine what it is for, which will allow you to make the right choice.
