Cement mortar can be considered the most popular and popular material in modern construction. Its strength characteristics will depend on the quality and ratio of the ingredients used. The proportions and composition are determined by the area of destination. Most often, concrete is used to equip foundations. The pace of construction will depend on how correctly it is possible to determine the required amount of building materials. And if the calculation of the required volume of bricks, as a rule, does not cause difficulties, then the determination of cement consumption, which goes to 1 cubic meter of mortar, can create some difficulties.
What affects the volume of cement in the preparation of the cube of the solution?
When choosing the composition of the mixture, it is necessary to remember that with an increase in the grade of cement the need for the use of an astringent will be reduced. In some cases, in order to maintain the structure of the mixture after setting, stone dust is added to it. In order to determine the question of how much cement is in 1 cube of the solution, you need to remember that the consumption of the mentioned ingredient depends on the type of mixture. Clay, sand or lime mortars may be used depending on the purpose. Each of these compositions uses its own ratio of aggregate and binder. Thus, in order to obtain a solution of cement and sand, these components are taken in a ratio of 1: 3 or 1: 4. To obtain a lime mortar, cement must be introduced in a ratio of 1 to 3 with respect to the lime component. When using clay, the volume of cement per 1 cubic meter of the solution changes, while using a proportion of 1: 9.
Cement consumption depending on the grade of mortar
The brand of the mixture determines the strength of the composition after solidification. This indicator is selected depending on in which structural element of the building the solution will be used. For example, for load-bearing walls and foundations, the strength of the masonry acts as a determining value. For this reason, it is recommended to use as strong solutions as possible. If you wondered how much cement is in 1 cube of mortar, then you need to remember that for internal walls it is permissible to use a mixture with a less impressive volume of cement. For plastering, mortars with a lower content of cement component can also be used.
The dependence of the brand of mortar on the volume of cement
If you are faced with the question of how much cement is in 1 cube of the solution, then you need to remember that the grade of the solution depends on the volume of cement used. Thus, to obtain a solution of grade M10 cement for the mentioned volume, 81 kilograms must be added. M25 will work out if you add 133 kilograms of binder. For the M50, it is necessary to prepare 178 kg, while for the M75 - 245 kilograms. If you are faced with the question of how much cement is in 1 cube of a solution of M100 brand, then it is worth noting that you need to use these ingredients in an amount equal to 306 kilograms. For the highest grades M150 and M200, it is necessary to add cement in the amount of 414 and 510 kilograms, respectively. Once you know how much cement is needed per 1 cubic meter of mortar, you can start acquiring the components for the work.
How much cement to add per 1 cube of solution?
It will be quite simple for the master to determine how much cement is needed per 1 cube of the solution. For this, it is necessary to take as a basis a certain ratio of aggregate and binder, as well as cement density. The last figure is 1300 kilograms per cubic meter. If the proportion of cement and aggregate is 1 to 4, then the composition will be 20% binder. Given the density, the consumption of this ingredient per cubic meter will be: 1300/5 = 260 kilograms. When visiting the store you have to buy 6 bags, since you will need 5 bags with a small one. Calculate the amount of binder, so you can always do it yourself.
Cooking Instructions
Once you know how much cement is needed for 1 cube of the solution, you can proceed to the theoretical question, namely, familiarization with the preparation technology. The solution should be kneaded with a concrete mixer, in a metal bath or in a wooden box, depending on what equipment you have available. First you have to mix dry components, including gravel, sand and cement. After all the components are well mixed, you can start adding water. In this case, do not stop mixing. Concrete pouring should be completed within 2 hours after preparation of the composition. As soon as the base is flooded, care must be taken to eliminate excess air bubbles using a deep vibrator.
Additional recommendations
Once you have decided how much cement is needed for 1 cube of the solution, you can begin to prepare the necessary equipment and materials. Filling should be carried out in the warm season. However, if there is a need for manipulation at sub-zero temperatures, then special substances can be added that contribute to the set of concrete strength under difficult conditions.
However, the master must be aware that under weather conditions that are characterized by minus temperature, the work will be difficult. It is necessary to heat the water, which will prevent the mixture from freezing. If ice formation is allowed, this can cause an increase in the volume of the solution, which, in turn, can lead to the destruction of the structure from the inside.
What volume of mortar is obtained from one bag of cement?
If you have 1 bag of cement available, how many cubes of mortar will come from it? Using this volume, you get 0.24 cubic meters of sand and cement, and you need to use a ratio of one to three. One part of the clay will need to be added to the ingredients. It will turn out to increase the volume of the solution to 0.25 cubic meters if you use cement grade M300. In the end, it will be possible to obtain a solution of the brand M75.
Conclusion
Work on the preparation of cement mortar should occur in compliance with the proportions. The correct ratio will allow to obtain a high-quality composition, which will differ in strength and frost resistance. It is important not only to properly prepare the mixture, following the technology, but also to monitor the hardening stage. At the same time, the surface of the structure must be moistened, which is especially important in hot weather. In this case, you can cover the surface with moistened burlap.
