Decades pass, but brick is still one of the most popular building materials. This is due to its durability, environmental friendliness, as well as high thermal insulation properties. However, the quality of the wall depends not only on this material, but also on the mortar, which must be easy to lay on the surface, have good adhesion to products, fill joints and be resistant to precipitation.
How to get high strength
It is possible to achieve high strength of the mortar by correctly determining the volume of cement, because the brick is laid only on a mortar with such a composition. Depending on the load and purpose of the structure, different brands of a binder solution can be used, to which cement of a certain type is added. Sometimes lime-cement mortar is used for the construction of internal partitions, wherebinder volume is reduced.
To increase plasticity, various substances are added to the ingredients. Sometimes even ordinary shampoo comes out among them. The main components are:
- water;
- cement;
- sand.
The proportion of the last two components usually looks like this: 1 to 4. This indicates that one fifth of the cement should be used for one cubic meter of mortar. Given that the weight of 1 m3 is approximately 1300 kg, then 260 kg of cement is used to prepare the composition.
Consumption of cement per masonry in one square meter
Before starting work, you need to find out what is the consumption of cement per 1 m2 of brick laying. This indicator will depend on the thickness of the wall: the larger it is, the more material will be required. If you build walls whose thickness is a quarter of a brick, then 5 kg of cement will be needed per square meter of masonry, this is true if the mortar is M-100.
Consumption of cement per 1 m2 of brick laying in kg will be mentioned below. The volume of cement is reduced to 4 kg if you prepare a solution of brand M-75. For M-50, you will need 2.5 kg of cement. The solution will be used for brickwork in the same way. Thus, for a cubic meter you need 300 kg. This is equal to the limit of 0.25 to 0.3m3 mortar per 1m3 surface. In this case, the ratio of sand and cement will look like this: 4 to 1. It will be necessary to achieve optimal rigidity andmobility.
Consumption of cement per 1 m2 of brick laying will change if the following are added during the mixing process:
- marble;
- clay;
- synthetic additives;
- limestone and other ingredients.
For reference
In this case, the ratio of sand and cement can decrease to 9 to 1. When the concrete is closed, then 500 kg of cement and no more will be used up for 1 m3 of the mixture. The exact characteristics of concrete can be found by reading the state standards. However, the consumption of cement per 1 m2 of brick laying may vary 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 dry cement and sand, to which water is gradually added in small portions. As a result, you should achieve a uniform composition that does not crack much and is solid. In this case, the masonry will last longer, the concrete will be strong, and the structure will be durable and highly reliable.
Varieties of cement mortar
Now you know the consumption of cement per 1 m2 of brick laying. However, before starting work, it is also important to know about the varieties of cement mortar. Bricks can be laid on mortar with limestone and other materials added to the ingredients. The consumption of cement in this case will be determined by the volumecomponents. Lime mixing is inferior to other solutions in terms of strength, therefore, such compositions are almost never used to create capital structures.
Cement-lime mass is plastic, so it can be used for laying bricks. When it comes to cement mix, the following components are used for its preparation:
- cement;
- water;
- sand.
Reliability, durability and strength will depend on the brand and quality of cement. The consumption of this component and the proportions of the components almost do not change. The most frequently changed brand. For example, for self-supporting walls, it decreases, while for load-bearing walls a higher grade is required. In order to get 1 m3 of the mixture, it is necessary to use cement in the amount of 8 bags, the volume of each of which will be 50 kg.
Its ratio with sand is as follows: 1 to 4. At the same time, to create one cubic meter of masonry, 0.3 m3 mortar and 405 bricks, the size of each of which will be 250x120x55 mm. In this case, the laying should be carried out in one brick.
Classification of cement mixtures
Cement consumption rates per 1 m2 brick laying were mentioned above. However, before starting work, it is also important to know the main types of cement mixtures. The first group includes cement-sand mortars or mustards. In their manufacture, a dry method is used, in which a drum oven is used. These blends are more expensive.compared to the purchase of cement and sand, but are more convenient due to the stable quality of the sand.
The second variety is cement mixtures with rheological additives, which include cellulose ethers that increase primary adhesion and water retention. They turn 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 that increase resistance to abrasion and tear.
Conclusion
Consumption of cement per 1 m2 of facing brick laying will remain the same as in the above case. This is true if the product will have the same size. As a rule, such laying is carried out in one brick, so you will not encounter an overrun of raw materials. The consumption of cement per 1 m2 of brick laying in half a brick will be exactly 2 times less.
