Cement consumption per 1 m2 brick masonry: types of cement mixture and its norms
Passes for decades, and the brick still remainsone of the most popular building materials. This is due to its longevity, environmental friendliness, and also high thermal insulation properties. However, the quality of the wall depends not only on this material, but also on the solution, which must be easily laid on the surface, have good adhesion to the products, fill the seams and be characterized by resistance to precipitation.
How to get high strength
To achieve high strength of the solution,correctly determining the volume of cement, because the brick is laid only on the solution with this composition. Depending on what the load and purpose of the structure, different brands of binder mortar can be used, to which cement of a certain type is added. Sometimes for the construction of internal partitions use lime-cement mortar, where the amount of binder is reduced.
To increase the plasticity, various substances are added to the ingredients. Sometimes even ordinary shampoo acts among them. The main components are:
- water;
- cement;
- sand.
The proportion of the last two components usually has the following form: 1 to 4. This indicates that one-fifth of the cement should be used for one cubic meter of the solution. Given that the weight of 1 m3 approximately 1300 kg, then 260 kg of cement is used for the preparation of the composition.
The consumption of cement per masonry in one square meter
Before starting work, you need to find out whatconsumption of cement per 1 m2 brick masonry. This indicator will depend on the thickness of the wall: the larger it is, the more material will be required. If you build walls with a thickness of a quarter of a brick, then 5 kg of cement will be needed per square meter of cement, which is true if the solution has the M-100 grade.
The cement consumption per 1 m2 brick masonry in kg will bementioned below. The volume of cement is reduced to 4 kg, if you prepare a solution of the brand M-75. For M-50 will need 2.5 kg of cement. The solution will be consumed on the brickwork equally. Thus, for a cubic meter you need 300 kg. This is the limit of 0.25 to 0.3 m3 solution per 1 m3 surface. The ratio of sand and cement will look like this: 4 to 1. It will be necessary to achieve optimum rigidity and mobility.
The consumption of cement per 1 m2 brick masonry will change if in the process of mixing are added:
- marble;
- clay;
- synthetic additives;
- Limestone and other components.
For reference
In this case, the ratio of sand and cement can decrease to 9 to 1. When the concrete is closed, then for 1 m3 mixture will be consumed 500 kg of cement and notmore. With the exact characteristics of concrete can be found by reading state standards. However, the consumption of cement per 1 m2 brick masonry may change if the builders pursue the goal of obtaining a certain density, viscosity characteristics and drying time.
But the technology remains the same. It involves mixing cement and sand in a dry form, to which water is gradually added in small portions. As a result, you must achieve uniformity of the composition, which does not crack strongly and is integral. In this case, the masonry will last longer, the concrete will be durable, and the structure will differ in durability and high reliability.
Varieties of cement mortar
Now you know the consumption of cement per 1 m2 of masonrybrick. However, before starting work it is important to know more about the varieties of cement mortar. Bricks can be laid on the mortar, to the ingredients of which add limestone and other materials. The cement consumption will be determined by the volume of the components. Lime kneading is inferior to other solutions in the issue of strength, so for the creation of capital structures such compounds are almost not used.
Cement-lime mass is plastic, so it can be used for laying bricks. When it comes to cement mixing, the following components are used for its preparation:
- cement;
- water;
- sand.
Reliability, durability and strength will bedepend on the brand and the quality of the cement. The consumption of this component and the proportions of the components are almost unchanged. The most frequently changed brand. For example, for self-supporting walls it decreases, whereas for carriers it is necessary to have a higher brand. In order to get 1 m3 mixture, it is necessary to use cement in the amount of 8 bags, the volume of each of which is 50 kg.
Its ratio with sand is as follows: 1 to 4. Thus for creation of one cubic meter of a laying it will be necessary 0,3 m.3 mortar and 405 bricks, the size of each of which is 250x120x55 mm. In this case, the masonry should be kept in one brick.
Classification of cement mixtures
Standards of cement consumption per 1 m2 Brick masonry was mentioned above. However, before starting work it is important to know also the main varieties of cement mixtures. The first group includes cement-sand mortars or gorkovki. When they are manufactured, a dry method is used, in which a drum furnace is used. Such mixtures are more costly compared to the purchase of cement and sand, but are more convenient because of the stable quality of the sand.
The second type is cement mixes withrheological additives, which include cellulose ethers, increasing primary adhesion and water retention. They convert the mixture into masonry mortar, tile adhesive or plaster. This group is more expensive, but is able to cover almost the entire area of use of cement mixtures. The third group is the most expensive, because it includes dry cement mixtures containing strength rheological additives, increasing resistance to abrasion and rupture.
Conclusion
Cement consumption per 1 m2 brick masonryfacing will remain the same as in the above case. This is true if the product is of the same size. As a rule, such a brickwork is carried out in one brick, so you will not run into a surplus of raw materials. The consumption of cement per 1 m2 brick masonry per half-brick will be less than exactly 2 times.
