This online Concrete Mix Calculator is designed to accurately determine and optimize the mix design for robust concrete by combining a cement binder with both coarse and fine aggregates. The calculator takes into account the effects of plasticizing additives, compaction techniques, and overall workability to help you achieve the perfect concrete mixture. Please note that the results provided are approximate and may differ from actual outcomes due to variations in material moisture and quality. For the greatest accuracy, performing a trial mix is recommended. Additionally, our tool computes the precise amount of cement required per cubic meter (1 m³) to ensure an exact estimation of both constituent materials and overall costs.
Constructing a concrete foundation for a residential house or engineering project is a critical process that greatly influences the strength and longevity of the final structure. The online Concrete Mix Calculator streamlines the process by determining the optimal mix composition and cost estimation for your aggregates and other building materials. Simply input the necessary data into the provided calculator fields. If you need to calculate the foundation structure itself, please visit the foundation calculation page.
The Concrete Mix Calculator offers an intuitive online service that includes:
Our calculator determines both the precise composition of your concrete mix and the associated cost of building materials based on the input parameters and selected aggregates. You can easily save your results as a PDF document or print the comprehensive report with a single click. It is essential to account for cement usage per cubic meter along with other materials to achieve an accurate mix design.
To obtain the final results, enter the following parameters into the concrete calculator fields for the foundation:

There are several primary types of foundations used in construction:
For private construction, the strip foundation is the most common option. To ensure the stability and longevity of the structure, consider the regional soil freezing depth—typically between 1.5 to 2.5 meters—when establishing the foundation depth. The above-ground portion of the foundation often reaches up to 0.5 meters, and the strip width should exceed the wall thickness by 100-150 mm, usually falling within the range of 300-400 mm.
The chosen concrete grade for the foundation depends on factors such as the wall materials and the number of floors in the future building. These specifications influence the workability of the mix. A more fluid and flowable concrete fills intricate formwork with dense reinforcement easily, while a stiffer mix—often requiring vibration compaction—develops strength more rapidly and is typically used for critical load-bearing elements such as staircases.
Advancements in chemical additives and construction technology have enhanced the role of plasticizers, which improve concrete by increasing plasticity and workability, reducing cement consumption, and boosting the longevity of the finished construction. Selecting the correct proportions is essential for accurate concrete calculation, especially when a specific density is required under various operational conditions. When planning concrete for flooring, always consider the necessary strength and wear resistance.
IMPORTANT! When calculating the required concrete volume, always account for material losses and potential inaccuracies by adding an extra 3-5% to the computed mix, or by keeping a reserve of larger aggregate pieces such as big stones or broken bricks for backfilling if necessary.
Concrete – a man-made stone material widely used in construction, composed of cement, either natural or synthetic aggregates, and water. Typically, concrete is produced by mixing Portland cement, gravel, and sand (plus screenings) with water. While standard concretes are commonly employed in both industrial and civil construction, specialized types include hydraulic, road, thermal insulation, and fire-resistant concretes.
Gravel – a non-metallic construction material obtained by crushing rocks and minerals into specified sizes or fractions.
Sand – a loose, sedimentary material formed by the weathering and breakdown of solid rocks, or produced by crushing larger rocks into small particles. It primarily includes pit sand and river (quartz) sand.
Screenings – fine rock particles generated as a byproduct during the production of crushed stone.
Plasticizers – chemical additives incorporated into concrete mixtures to enhance physical and chemical properties. In concrete, plasticizers improve mix mobility and workability, lower binder consumption, and enhance the durability of the final structure.
Grillage – the primary structural framework of a columnar or pile foundation, typically made of reinforced concrete, steel, or wooden beams, which serves as the base for constructing the building walls.
