What are FBS foundation blocks

High-quality heavy concrete reinforced concrete components serve as the foundation blocks in structural construction. Products are made in the shape of a parallelepiped that is rectangular. During the production stage, metal rods can be used to reinforce blocks. In order for the elements to support large weight loads, this helps to strengthen them.

Each element has two metal eyes to make loading, unloading, and installation of products easier. In order to guarantee a sturdy and dependable bond between products during installation, masonry mortar is filled into tiny indentations carved out of the ends of the blocks.

As the name implies, foundation concrete blocks are mainly used to build sturdy and dependable foundations for a variety of buildings. This does not, however, restrict the scope of their application. FBS are required for any complexity of building and installation work.

Multistory buildings, technical buildings, non-residential buildings, and industrial facilities are among the many projects for which they are frequently utilized. Due to the fact that with the help of products a quick construction process is carried out, foundation blocks are in demand in the construction of temporary and permanent fences and large construction projects.

Advantages and disadvantages of reinforced concrete blocks for foundations

For foundations, builders know that concrete blocks work well for structures of all kinds of complexity. This is because the products have certain advantages over the conventional method of pouring concrete foundations.

The material exhibits good load-bearing capacity and high strength properties. It is more resilient to fire, moisture, and temperature changes. The installation of foundation blocks during object construction can take place in any climate region at any time of the year because of their enhanced resistance to frost and decreased thermal conductivity.

The material is resilient to a number of natural occurrences, such as soil heaving in the spring and erosion caused by groundwater. Because of the material’s enhanced resistance, foundation blocks can be installed in unfavorable environments like icy and acidic soils. Rocky soils are the sole exceptions.

When products are used in foundation construction, a dependable and long-lasting base with a minimum 60-year service life is created. This is because the products are produced in factories where rigorous laboratory quality control is applied to both the composition of the working solution and the final product, and production technology is closely monitored.

The foundation blocks’ remarkable dimensions and consistent geometric shape make it easier and faster to install products. This considerably lowers the time and cost of labor required to complete the task. You don’t have to wait for the solution to set before moving on to the next step once installation is finished. Economic benefits are provided by this feature, which is crucial for large-scale construction projects.

One drawback is the expensive price of blocks. The substantial weight of the reinforced concrete foundation blocks will necessitate the use of specialized equipment during installation. The construction site needs to have adequate room for equipment and the storage of any leftover materials. There will also be insufficient tightness in the joints between the elements, necessitating the use of extra insulation.

How foundation blocks are made: technology features

Every manufacturer who produces high-quality concrete blocks for the foundation must strictly adhere to the prescribed sequence of actions and maintain the design ratio of the constituent ingredients. Aggregates, water, and cement powder are combined to create the working solution.

The mixture is forced into a uniform consistency in a forced-type concrete mixer used to prepare the batch. The final mixture is poured into unique metal molds that have had industrial lubricant applied to their inner walls beforehand. At this point, reinforcement can be installed, which has an impact on the products’ strength attributes and the cost of the foundational blocks. Each mold has multiple compartments and detachable sides that make it simple and quick to remove products from it with a crane.

After the mixture is evenly distributed by the molder, the concrete is vibrated either directly on the vibrating platform or via the use of a portable deep vibrator. The process of completely compacting the semi-liquid material is now completed.

Crucial! Since excessive vibration will cause concrete to delaminate, the length of the vibration process is strictly regulated.

A trowel is used to smooth the products’ surface following vibration. After the products are taken out of the molds, a film covering is applied to keep them safe. The blocks are then irrigated. Steaming chambers are where the process is carried out. After the blocks are allowed to dry completely for seven days, the products become more tempering. After 28 days, the material reaches its maximum strength.

Dimensional characteristics of FBS reinforced concrete blocks

The size of concrete blocks is a crucial characteristic. Current regulations tightly control a product’s height, width, and length. The calculated load of the object on the base, which has to support the weight of the structure and distribute it uniformly throughout the whole perimeter, is used to determine the block dimensions.

Crucial! A poor choice of block sizes will eventually cause the building to collapse.

The dimensions of the blocks directly affect the strength of the future structure, the technological process of installing elements, the duration of the "zero cycle," and the cost of the products. The type of soil and its bearing capacity are taken into consideration when choosing the block sizes. The blocks should be larger in areas where the soil is less stable. It is best to use the largest elements when building on clay foundations. Coarse soils are suited for smaller products. For a small building, a foundation composed of 20x20x40 cm blocks is the most common choice.

Excellent guidance! Utilizing foundation blocks of various sizes, maximum packing density is ensured in order to produce a dependable and long-lasting foundation.

The weight of the structure, which is based on the building’s size and type of materials, the thickness of the walls and ceilings, and the number of storeys are all significant factors. Additionally, the kind of masonry is taken into consideration when choosing the block sizes. It is important to keep in mind that five blocks are ideal for each wall length.

FBS blocks are offered in 15 standard sizes, per GOST. The product’s length ranges from 880 to 2380 mm. There are four widths available for blocks: 300, 400, 500, and 600 mm. The product’s height ranges from 280 to 580 mm. The largest element is 2380x600x580 mm in size, while the smallest is 880x300x580 mm. A lot of manufacturers make foundation blocks that are 200 x 200 x 400 mm and can be laid without the need for specialized tools.

How to choose the right size of the FBS foundation block

Foundation blocks come in different sizes and are used to build foundations. The element’s dimensions directly affect the product’s price per unit. The base is scanned to determine the appropriate size and quantity of FBS. On a unique drawing, the length and height of each component of the base are indicated. This includes the 25 mm of bandaging that is present between the elements.

The future building’s wall thickness is taken into consideration when choosing the block width. Here, small overhangs of above-ground components are permitted. Indentation values on brick walls should be approximately 40 mm on each side. Blocks 600 mm wide can be used for load-bearing structures whose walls are 510 mm thick, while 500 mm wide products can be used for walls whose thickness is 640 mm.

The development dictates the length of the foundation, where components of various sizes should be schematically arranged to guarantee even laying and the absence of noticeable protrusions.

Crucial! Standard size products can then be divided along the length of the base if they cannot be arranged correctly along its length.

The blocks used for walls and foundation construction have a height of 580 mm. Items measuring 280 mm are utilized as extra parts when creating communication inputs and outputs, such as vent holes in the base.

The weight of the foundation block is a crucial factor to consider when selecting product dimensions because it has an impact on transportation logistics. The product weighs between 380 and 1960 kilograms. Selecting a vehicle for the purpose of transporting materials to the construction site is essential. The selection of specialized equipment for the direct product laying process is based on the load capacity.

Small-sized foundation blocks for small buildings

The industry standard states that 400 and 600 mm lengths of small-sized foundation blocks are available. These products have a low weight and great strength. The products can be used to build the foundations of a structure made of wood or foam concrete because foundation blocks are primarily made from heavy grades of concrete with good load-bearing capacity.

The financial cost of construction is decreased because lifting equipment is not needed for their installation. Nevertheless, the use of 20x20x40 cm foundation concrete blocks lengthens the project’s completion time and raises labor expenses.

Products are frequently utilized in the construction of cellar and basement walls, as well as foundations on sandy soils. For small cottages or country houses, building a columnar foundation out of 20x20x40 cm blocks is a good and affordable solution. Such components should be used in conjunction with cast strip foundations. Experts frequently utilize 20x20x20 cm foundation concrete blocks as extra components, which allow you to drill holes in the base for utility lines or vents.

Small foundation blocks work well as supporting elements in basements, semi-basements, and other spaces where they are not intended to be used for load-bearing walls, columns, or fences.

There are several varieties of foundation blocks, each suitable for a particular type of construction and soil. It is important to understand the unique advantages and uses of each type of concrete block, whether you’re using solid blocks for heavy loads, hollow blocks for better insulation, or aerated blocks for lightweight and easy handling.

Types of concrete blocks for the foundation by type of material

Different types of concrete mixes can be used to make foundation blocks, according to GOST. There are various product types based on this. Heavy grades of concrete are mostly used to make cement, concrete, and reinforced concrete products. This helps to create blocks with maximum density, which are distinguished by high bearing capacity. These foundation blocks are dependable and long-lasting when used to create bases and designs.

Crucial! A crumb of granite or basalt is added to the blocks to give the finished solution extra strength.

The process used to produce silicate foundation blocks is similar to that used to make bricks. Working solutions consist of silicate-based concrete, with high-brand cement making up no more than 14% of the total volume. The collections are heated to a specific temperature and then gradually cooled to obtain adequate strength. Slag from ground blasting is added to silicate products to improve their waterproofing properties.

Expanded clay, found in Ceramzitonic foundation blocks, increases the set of strength by up to 70%. The class of light materials is represented by this kind of product. These are the building blocks that go under the hands.

Crucial! Complex structures are frequently built using silicate foundation blocks and expanded clay concrete.

Cinder blocks are a well-known variation of foundation blocks that date back to the Soviet era. Its manufacture involved the use of blast furnace slag. These days, the finished mixture is supplemented with gravel, sand, crushed stone, broken brick, sawdust, perlite, and waste from concrete construction. The kind of filler determines the product’s technical specifications. The low cost of cinder blocks, coupled with their uneven and unsightly surface, makes them a popular material for building garages and small residential structures.

There are many different kinds of foundation blocks, and each has advantages that are specific to your building project. Every type of building situation has a suitable block, from strong reinforced concrete to lightweight aerated ones.

Selecting the appropriate kind of foundation block is essential to guaranteeing the longevity and steadiness of your building. When choosing, take into account elements like insulation qualities, moisture resistance, and load-bearing capacity.
