reliability and durability of the monolithic construction design depends on a rational proportionthe composition of the concrete mix, the quality characteristics of its components and the method of exposure to obtain the desired density.Alternatively, you can order a ready-mixed concrete factory production of the necessary mark and gravel fractions.

Often the implementation of self-construction, few adhere to the correct dosage of the material, the mobility indicators and curing of concrete.In order to facilitate laying of a finished batch is added not control the amount of water that leads to disruption of water-cement ratio, the loss of durability and strength of the house foundation.Therefore, it is advisable to precisely determine the proper ratio of sand, gravel, cement and water.

How to calculate the composition of the concrete of 1 m3?

Calculation of concrete solution involves the use of special technology arithmetic algorithms:

  • by the ratio of the specific weight of cement, sand and gravel;
  • flow rate of the mixture at the rate of 1 kg / 1 m3.

In the first case the formula becomes:

D: P: u where

  • C - cement (equal to one);
  • P - sand;
  • ni - rubble.

When the calculation should take into account water-cement ratio and the percentage of the addition of plasticizers.

Calculation of concrete per 1 m3 made on the basis of a water-cement ratio, which depends on the anticipated terms of sealing, strength, frost resistance, water resistance.Water flow is established, based on the water absorption aggregate.The relevant parameters are listed in a specially designed tables that allow for the consumption of cement using sand and gravel with an average of factionalism water demand of 5-7%.

Calculator concrete structure will ensure the qualitative characteristics of concrete mix:

  • strength;
  • humidity;
  • density;
  • mobility;
  • waterproof.

of concrete Calculation Online provides an introduction to the field of concrete programs relevant volume settings and its brands.Modern technology of concrete are diverse requirements for it.His selection is due to the appointment.Lightweight concretes are characterized by low bulk density and high thermal insulation properties, while the heavy guarantee small porosity, high strength and abrasion resistance to external factors.

Online concrete calculator allows to calculate the correct value for the material and bring it to the required number.This approach greatly simplifies the calculation technology, enabling financial savings.Note that the error produced by the calculation is about 20%.The calculator is not a professional option, because it does not take into account the aggregate factionalism and the level of humidity.It is therefore important to check compliance with the requirements of concrete construction and GOST standards.
