Weight of a concrete block depending on the type and size

Concrete blocks are an essential part of many building projects because of their strength and adaptability. Comprehending the weight of concrete blocks is essential for both planning and executing construction projects, be it a large commercial building or a garden wall. The weight of a concrete block varies greatly depending on its size and type, which affects everything from structural support to transportation.

Concrete blocks come in three different varieties: solid, hollow, and aerated. Each has its own characteristics and weight. While hollow blocks are lighter and frequently used for non-load-bearing partitions, solid blocks are usually heavier and used for load-bearing walls. Because of their light weight and insulating qualities, aerated concrete blocks are becoming more and more common in contemporary architecture.

The weight of a concrete block is also largely determined by its dimensions. Although blocks typically measure 8 by 8 by 16 inches, they can be purchased in a variety of sizes to meet different building requirements. Larger blocks can improve structural integrity by reducing the number of joints and are easier to handle, but they may also require more units and mortar.

For effective project planning, it is imperative to comprehend these variances. Understanding the weight of the blocks you’re using is helpful when figuring out how much weight a structure can support, organizing logistics for transportation, and estimating material costs. A smoother, more successful construction process is ensured by having a clear understanding of the weights involved, whether you’re a professional builder or a do-it-yourself enthusiast.

Type of Concrete Block	Weight (kg)
Solid Concrete Block (40x20x20 cm)	28-30
Hollow Concrete Block (40x20x20 cm)	15-18
Lightweight Concrete Block (40x20x20 cm)	10-12
Insulated Concrete Block (40x20x20 cm)	20-22

Anyone working in construction needs to be aware of a concrete block’s weight because it affects handling, transportation, and structural design. A concrete block’s weight varies according to its size and type (solid, hollow, aerated, etc.). With the purpose of assisting you in making wise decisions for your construction projects, this article will examine the various varieties of concrete blocks, their typical dimensions, and the ways in which these elements affect their weight.

How to determine the weight of a concrete block

You must consult the manufacturer’s documentation to determine the weight of a concrete block. Because concrete’s density cannot be ascertained outside of a laboratory and weight is an indicator of this value, knowing the mass of the material is also necessary for quality control.

Concrete blocks are utilized for building foundations, fences, walls in monolithic high-rise structures, and walls in low-rise construction. Standards control the weight, dimensions, and strength properties of concrete products.

• by size;
• by shape (with voids, with recesses and grooves);
• by composition (made of heavy or lightweight concrete, reinforced concrete, wood-concrete and others).

Remark: By determining the mass of a construction component, you can compute its density and contrast it with the values mentioned in the related paperwork. As a result, the site inspects the building material’s quality.

Features of foundation concrete blocks

They are employed in the building of outbuilding walls, cellars, and basements. Their primary goal is to distribute the load across the base equally.

Concrete used to make foundation blocks must have a density of at least 1800 kg/cm3. Regulations dictate the grade of concrete, and manufacturers have to abide by them.

The following are building blocks for foundations:

• solid foundation blocks (FBS);
• foundation blocks with a cutout (FBV);
• hollow foundation blocks (FBP).

The engineering-geophysical conditions of construction, the geological, hydrological, and economic factors are considered when choosing the type of foundation and products.

When using finished products, you can compute the necessary amount of materials with accuracy because the work is completed quickly and their sizes are standard.

Foundation blocks of solid section

Strip foundations and house basement wall arrangements are done using FBS. They are composed of dense silicate, expanded clay, or heavy concrete grades no lower than M100, and they have a sizable bearing capacity.

Product reference weight:

• made of heavy concrete – 1.05-1.4 tons;
• made of silicate – 0.88-1.17 tons;
• from expanded clay concrete – 0.79-1.05 t.

Because FBS have a rectangular parallelepiped shape, you can calculate the mass by knowing its dimensions.

Note: FBS 24.5.6-T, for instance, is constructed of heavy concrete, which has a bulk density of 2500 kg/m3. We calculate the dimensions, which come to 2.4 m * 0.5 m * 0.6 m based on the marking.

• The volume is 0.5 * 0.6 * 2.4 = 0.72 m3
• We multiply this value by the bulk density and get 0.72 * 2500 = 1800 kg
• This simplified calculation is used in the field, for example, to calculate the mass of dismantled structures. To accurately determine the weight of the block, you need to use the product passport.

Foundation blocks with a cutout

Lintels, beams, pipes, cables, and other communications materials can be laid in recesses in these structures. They serve as extra components for foundations or basement walls.

The mass of the structure will vary based on the type of concrete used.

Remark: The markings on the blocks specify the kind of concrete that goes into them. FBV-L is light, FBV-S is silicate, FBV-K is expanded clay concrete, and FBV-T is heavy.

Hollow core foundation blocks

FBPs are hollow constructions packed with monolithic concrete, crushed stone, sand, or insulation. Reinforcement bars are sometimes inserted into the voids for added strength.

They are a component of the walls of the basement, the foundation, and the unheated rooms. FBP is a popular material in low-rise private construction because of its low cost.

They are lighter and exhibit better sound and thermal insulation qualities than FBS and FBV.

Types and weight of wall blocks

These days, wall blocks are a common material for creating load-bearing walls and partitions in buildings for a variety of uses. They are made of concrete with fillers and additives, and they come in a variety of sizes and shapes.

These are, depending on composition:

• expanded clay concrete;
• foam concrete;
• aerated concrete;
• arbolite;
• polystyrene concrete, etc.d.

Please take note that all smaller products are classified as small-sized; large-sized products are 600x300x200 mm and larger.

Load-bearing walls are built using large wall structures; the transportation and installation of such a large mass necessitate the use of specialized equipment.

Block use reduces construction costs because it saves time when compared to brickwork. They don’t need cladding, are simpler to work with, and have good sound and heat insulation qualities.

Expanded clay concrete blocks

Cement, water, and expanded clay are used to make them. This material is fireproof, frost-resistant, highly insulating against sound and heat, and porous. Chimneys, fireplaces, foundations, walls, and partitions are all built with expanded clay concrete.

The proportions of the components determine the expanded clay concrete’s weight and strength. This material has a bulk density of 700–1200 kg/m3.

Note: There are two types of expanded clay concrete blocks: hollow and solid. Hollow products weigh between 4 and 17 kg, while monolithic products can weigh up to 30 kg.

The density and grade of the concrete are the primary determinants of the weight of expanded clay concrete. The weight of the structure increases with increasing density. A weight table for 200x200x400 mm blocks broken down by concrete grade can be found below.

A significant amount of expanded clay concrete product suggests that either production technology has not been followed, there is too much moisture present, or some of the expanded clay has been replaced with slag or crushed stone. This has an impact on the building material’s strength, thermal conductivity, and quality.

The quality should always come first when purchasing expanded clay concrete, not the price. Purchasing materials from reliable manufacturers is crucial, and certificates of conformance should be obtained.

Foam concrete blocks

Cement, sand, and a unique whipped foaming agent are combined to create foam concrete. Prior to being combined into a single mass and poured into molds, the two compositions are first made independently and allowed to dry naturally.

Foam concrete is used for insulation in outbuildings, roofs, ceilings, floors, and the erection of load-bearing elements in low-rise construction.

In addition to being strong, foam concrete structures are easy to work with, offer excellent noise insulation, low thermal conductivity, fire safety, and resistance to fire.

Note: the density (D or D) of this building material determines its grades. Foam concrete D500, for instance, indicates that 1 m3 contains 500 kg of solids and the remaining volume is air.

In terms of intent, they are:

• structural (the most durable D up to 1200 kg/m3);
• structural and insulating (D = 600–800 kg/m3);
• heat-insulating (D = 400–500 kg/m3).

Note: You can use this table to calculate the weight of a product if you know its dimensions and density. Foam blocks D600, for instance, measure 0.2*0.3*0.6 meters; their volume is 0.2*0.3*0.6 = 0.036 m3, and their weight is 600*0.036 = 21.6 kg.

Products made of foam concrete come in a range of weights, volumes, and sizes for use in construction. Blocks of the same size will weigh differently depending on the brand of foam concrete.

Foam concrete is a popular building material because of its cost-effectiveness, cost-effectiveness, and ease of installation. The manufacturer’s instructions are followed when building a structure by hand. These instructions specify the steps to take and the additional tools and materials that are required. The blocks’ comparatively light weight enables you to expedite completion of the required work and save on transportation.

Aerated concrete blocks

Aerated concrete, a different kind of block, is made of cellular components and has a porous structure. Portland cement serves as the foundation for aerated concrete, and aluminum powder is added as a loosening agent. Autoclave furnaces are used for hardening, which gives the finished products a uniform structure and great strength.

Aerated concrete blocks can be used to construct a variety of things, including walls and partitions, garages, baths, fences, and low-rise buildings. They exhibit high levels of frost resistance, fire resistance, and sound and thermal insulation.

Note: When compared to brickwork, aerated concrete offers three times better heat retention and twice as much noise protection.

Note: Low bending strength is one of the drawbacks of aerated concrete constructions.

Note: You can determine a product’s weight by multiplying its volume (m3) by its density (kg/m3) and weight (in kg).

According to density, aerated concrete and foam concrete are classified by grade. The weight of the aerated concrete block is displayed in the table.

Anyone working on building or renovating projects needs to know how much a concrete block weighs. The kind and dimensions of the block have a major impact on the weight. You can more effectively budget for labor, transportation, and structural support if you are aware of these specifics.

There are various varieties of concrete blocks, including aerated, hollow, and solid. Every type has unique weight properties. Solid blocks, for example, are the heaviest and offer the greatest strength and stability. Because of the voids inside, hollow blocks are lighter and easier to handle while still providing strong structural support. The lightest blocks are aerated ones, which are created from easily workable materials like autoclaved aerated concrete (AAC), which also has superior insulating qualities.

The block’s weight is also significantly influenced by its size. Larger blocks are usually used for larger structures or foundation work because they naturally weigh more. Since they weigh less, smaller blocks are frequently used for walls and partitions. To maximize the effectiveness and efficiency of your project, choose the right block size and type.

In summary, a concrete block’s weight is a critical component that affects a variety of building-related factors. You can make sure that your building process is both practical and effective by giving careful consideration to the block’s size and type. With improved planning and execution made possible by this knowledge, the project will ultimately be more successful.
