In the construction industry, stone is an indispensable material, widely used in many different types of projects. Currently, there are many types of stones available in the market, each with its own size and features, suitable for various technical requirements and intended uses.

Some common types of stones such as 0x4, 1x2, 3x4, 4x6, and 5x7 are frequently used for foundation construction, road building, or creating solid concrete structures. In addition, there are also types of sanded stone and dust stone, which play an important role in the bedding layer, improving concrete quality, or processing road surfaces.

Each type of stone has its own specific characteristics to meet the precise requirements of different projects. Let's explore each of these construction stones in more detail with SMC Concrete, so you can make the right choice for your project!

0x4 stone, also known as crushed stone, is an essential building material produced from natural stones. This stone mixture ranges from dust stone to stones with a maximum size of 40mm.
With its characteristic rough surface, 0x4 stone has excellent bonding ability when mixed with cement mortar, making it superior to gravel. Therefore, it is widely used in construction projects, especially for road base courses, repairs, and road surface regeneration. 0x4 stone not only enhances the durability of the structure but also improves its load-bearing capacity, ensuring quality for all projects.

1x2 construction stone is a popular material in civil construction projects. This stone is categorized from natural stone products such as green stone and black stone and is typically in block form.
1x2 stone has the advantage of having fewer impurities and flat particles, ensuring high durability when used. The stones are cleaned through screening and washing to make them ideal concrete aggregates.
Common sizes for 1x2 stones today include 10x16mm, 10x22mm, and 10x28mm, meeting the diverse needs of construction.
Due to its excellent bonding with cement and strong compressive strength, 1x2 stone is commonly used in concrete slab pouring. It is also used in mixing with hot asphalt or ready-mix concrete for road construction and other building projects.

3x4 stone, with sizes ranging from 30-40mm, is a common building material used in various projects. This stone is highly durable and is widely used in house construction, especially in foundation projects or any structure requiring strong stability.
Additionally, 3x4 stone is applied in road construction, where high load-bearing capacity and long-term durability are required. Its exceptional characteristics make it an ideal choice for projects requiring stability and impact resistance.

4x6 stone, also known as standard crushed stone or macadam, is a building material with sizes ranging from 40-60mm. It is produced by sieving and separating other stone products and meets strict standards with mud, dust, and clay content not exceeding 0.4%, with no soft or weathered particles and a maximum of 7.4% flat particles.
With relatively uniform size, 4x6 stone has excellent compressive strength, making it ideal for construction projects such as foundation concrete layers, increasing the project's longevity. This stone also has moderate abrasion resistance, good adhesion to asphalt, and good chemical durability, making it suitable for creating road surfaces or as concrete aggregate for traffic infrastructure.

5x7 stone, with sizes ranging from 50-70mm, is produced from various natural stone types. With its high load-bearing capacity, 5x7 stone is commonly used in projects that require durability, such as concrete pouring, bridges, and traffic infrastructure. This stone is also used as a base for floor tiles and floor coverings, enhancing stability and durability for building projects.

Sanded stone is a type of small-sized stone widely used in many fields. It is used as a material for concrete pouring, playing an important role in traffic projects, roadbed construction, and other building projects. Additionally, sanded stone is a key component in hot asphalt, cold asphalt, and is used for paving foundations, road surfaces, and producing concrete slabs.
Dust stone, or stone powder, is a type of fine stone with sizes smaller than 5mm, formed as a byproduct in the production of other stones through crushing. With its smooth, lightweight, and shiny structure, dust stone can replace sand in many construction applications, saving costs while ensuring the quality of the project.
Due to these properties, dust stone is increasingly used in various construction technologies. It is often used as a base for floor tiles, in concrete pipe production, and as an additive for other construction materials, improving efficiency and durability.

Sanded stone, also known as 0x5 stone, is a small-sized stone ranging from 3-14mm, produced by sieving other stones like 1x2, 2x3, or 4x6. This stone is finely graded and easy to use in many construction applications.
Today, sanded stone is commonly used in producing block tiles, floor tiles, and as a base for floor tiles, enhancing both durability and aesthetics for construction projects. Additionally, it is used as an additive in hot and cold asphalt concrete, as well as directly spread over road surfaces to improve the quality and durability of traffic infrastructure.

Hock stone is a natural stone mined from large quarries and cut into various-sized blocks. This stone is known for its high compressive strength and excellent durability, which helps increase the lifespan of structures. Hock stone is less affected by external environmental factors and has good water resistance and electrical insulation properties.
In construction, hock stone is commonly used for building house foundations, especially in residential projects or areas with rocky terrain. However, when using hock stone, it is important not to apply it in areas with unstable soil layers, as this may affect the stability and quality of the project.
