Calculation of the composition and proportions of mortars

Information on the purpose of the calculator

Mortar calculator is designed to calculate the proportions and composition of cement-sand and cement-expanded clay solutions, the selection of the necessary mobility and cost calculation.

Construction is an area in which it is impossible to do without cement mortar. The strength of the mortar depends on which brand of cement you will use, on the size of the sand and compliance with the rules of hardening. The mortar must be used no later than 30 minutes after manufacture.

Method of preparation of mortar.

Sand and cement are mixed dry in the required proportions, and gradually poured with water in portions, until the desired mobility is obtained. If necessary, the estimated amount of plasticizers is initially diluted in water. In order to avoid the solution sticking to the walls of the concrete mixer, it is necessary to pour water into the mixture in small portions.

The required brand of solution depends on the brand of materials used. For example, when bricklaying with the brand of brick M100, it is necessary to mix a solution of the same brand. To prepare a solution for the foundation base, you can use a solution of less strength than the strength grade of the foundation. To calculate the required grade and mobility, use the calculator for selecting the composition and proportions of mortar.

For more comfortable work with cement mortars, it is necessary to use plasticizers, or ordinary detergents for household work. They help to achieve the plasticity of the solution and simplify the mixing process. The choice of plasticizers is quite large, it is necessary to choose the most suitable for your conditions, for example, in cold weather you need to use plasticizers with antifreeze additives.

For laying bricks and building blocks, there are "warm" solutions, with the addition of heat-saving binders, such as expanded polystyrene, expanded clay and perlite sand. Such solutions prevent heat loss through the "cold bridges" and make the wall more monolithic in its properties.

The following is a complete list of calculations performed with a brief description of each item.

General information on the results of calculations

• Amount of cement
- The total estimated amount of required cement for the entire solution.
• Amount of water
- The total estimated amount of required water for the entire volume. Attention! The final amount of water is selected experimentally, depending on the humidity of the sand.
• Number of fine aggregate
- The total amount of sand (filler) for the entire volume in kilograms.
• The density of the mortar
- The density of the mortar in the raw state.
• Water/Cement
- Water-cement ratio.
• Proportions of mortar
- The relative ratio of the components of the mortar.
• Cost
- The cost of each material and the total for the entire volume.
