There are several varieties of concrete solution, which differ both in quality and in proportional composition. The use of a particular variant of the solution is determined individually, depending on the place of concreting. We learn about how to make concrete with our own hands further.
The most important component of concrete solution is cement. Its function is to tie the other components among themselves. Portland cement is an ideal option for making concrete. This is due to the fact that it contains a large amount of calcium silicates. Thus, it is possible to achieve high adhesion between all components.
The type of cement used in the process of manufacturing a concrete solution is determined by individual indicators of the sphere of its use. Most often, brand 500 cement is used. The lower in quality of the brand is used to prepare concrete for surfaces that are not exposed to high load.
Portland cement is used to improve adhesion between all components at both high and low temperatures. However, the minimum use of the concrete solution is fifteen degrees. If concrete is still used at low temperature, then special substances in the form of additives and plasticizers should contain in its composition. A substance in the form of slag portland cement is used if the work is carried out at a temperature above 25 degrees of heat.
The amount of impurities in the cement substance should not exceed twenty percent. This is indicated in the marking with the designated letter D. When choosing a cement for the solution, pay attention to its external indicators. It should differ in federation and should not contain additional moisture. The material that has lumps and is distinguished by a raw appearance is not recommended to buy.
Responsible elements are erected from concrete, which, due to the poor quality of cement, will quickly collapse. The material should also be stored in specially designated conditions, at a temperature of 10 degrees of heat and humidity not higher than 60%. Cement easily absorbs moisture from the external environment, smells and quickly loses its positive characteristics. We recommend buying fresh cement, which will be used for one or two weeks.
The second component of concrete solution is sand. There are varieties of concrete solutions in which you can do without sand. This is possible only when the composition of the filler has no intervals or they are minimal.
The optimal sand fraction is from one to five millimeters. When choosing sand, give preference to materials that have the same grains of sand. Sand should not contain clay and other impurities. The presence of the remains of vegetation, stones, construction waste - negatively affects the quality of the resulting concrete solution.
In the presence of not too clean sand, we recommend that you sift it several times before use. The best option is the use of river sand, the cost of which is slightly higher than usual. However, such material does not have clay and extraneous inclusions and is characterized by good performance.
The presence of clay in concrete is unacceptable, it negatively affects its strength and duration of operation. The next moment is to ensure maximum concrete adhesion and a large aggregate. These factors are the main ones in determining the general strength of the concrete solution. In order to prepare the sand for work, we recommend rinse it and leave it for upset.
If you could not purchase high -quality sand, then the option of using artificial sand is possible. For its manufacture, rocks are finely separated. Such sand has greater density and weight. Keep in mind that a concrete solution of such sand will differ in great weight.
To increase the strength of the concrete solution, crushed stone or gravel is added to it. They perform the function of the filler of the concrete solution. It is not recommended to use pebbles for these purposes, since its surface is smooth.
When choosing a filler, ask from which breed it is made. Ceramzite substance is light, but it connects all the components to each other well. The size of the filler is from 0.8 to 4 cm. At the same time, it is recommended to choose the average in size of the substance. It is recommended to choose a substance that does not contain dust and clay inclusions. The reliability of the clutch is determined by the roughness of the material.
Add the filler to the concrete solution, which contains both large and medium particles. Thus, it is possible to achieve a more tight fit of the aggregate to the surface. Sand and filler should be located next to the venue. In order to prevent pollution of sand or filler, we recommend pour them on the base pre -covered with a film.
The last of the main components of the concrete solution is water. Its composition should not contain alkaline or acid inclusions.
As additional components for concrete solution, substances are used in the form:
1. Izniya.
With this material, the convenience of laying a concrete solution increases. Thus, it is possible to improve the process of leveling the concrete solution. Lime reduces the strength of the solution, as the connection between cement and aggregates decreases. Keep in mind that lime must be extinguished.
2. Plasticizers.
In order to make decorative concrete with hands, it is recommended to use substances in the form of plasticizers. With their help, it is possible to change the qualitative characteristics of the solution.
3. Additional components.
Using certain components, the concrete solution becomes more progressive. In addition, using the use of additives, it is possible to improve the captivity of the concrete solution. Before using additives, study their characteristics and instructions for use. If the work on pouring concrete is performed at low temperature, then you can not do without additives.
4. reinforcing components.
Using special additives, it is possible to perform additional reinforcement of the concrete solution. For example, it is recommended to add fibers based on polypropylene or polyvinyl chloride in a concrete solution with which a screed is performed. These components are characterized by softness and special strength. Thus, it is possible to achieve the perfect smoothness of concrete and its cracking is prevented.
The composition of concrete and the amount of compound of its components is determined by the purpose of using a concrete solution. For example, in order to build a foundation, it is necessary to have durable concrete, which contains large crushed stone and solution, reliably fixing it.
At the same time, it is important to achieve fluidity of the solution, since it should not contain air bubbles or extraneous inclusions. Before starting the solution, it is recommended to make a substrate. To do this, it is enough to use a less durable solution of a solution containing inclusions from small sand. At the same time, the consistency of the solution resembles wet soil.
A solution for the foundation can be made by concrete with your hands. At the same time, the filler should be average in fractional size, and consistency - fluid. Thus, it is possible to distribute the solution on the surface. In addition, the filler of small or medium fraction is used for the manufacture of flowerpots, garden elements, and concrete balusters.
The composition and number of components that contain a concrete solution are determined by a snip. In this case, the density of each ingredient should be taken into account. We recommend stopping on a concrete solution of medium density. After performing calculations, proceed to connect the components with each other.
The most popular option for the correlation of components involves the use of one part of the cement to three parts of the sand and six parts of the filler, while the amount of water varies from 0.4 to 1. The water makes the solution more or less fluid.
After determining the optimal consistency of the solution, the components should be measured. Keep in mind that it is not recommended to use wet sand for work, it is recommended to dry it to the solution before adding it to the solution.
Before making concrete steps with your own hands, it is necessary to prepare a concrete solution. Most often, a concrete mixer is used for this. This device allows you to evenly and quickly mix all the components. The manual method of preparing concrete solution is relevant only if the volume of work is small. At the same time, the possibility of controlling the recipe in this case is absent.
There are two ways with which it is possible to build a concrete solution independently:
1. First, dry ingredients are compounded, and then water is added.
2. Sand, aggregate and cement are added to the water.
The first option is also called dry, while uniform mixing of all components is carried out. At the same time, water is added last. Sometimes, this composition contains dry lumps that reduce the strength of the solution. In order to avoid their appearance, we recommend resorting to the second method of mixing the solution. It is suitable for kneading concrete in small quantities.
In any case, we still recommend using a concrete mixer for a batch of a solution. If you do not have this device, then take it for rent. The concrete mixer should be located near the venue. Thus, it is possible to avoid concrete stratification during its transportation.
The standard concrete mixer contains about two hundred liters of solution. This amount should be focused on when performing calculations of the number of ingredients. The process of preparing a solution in a concrete mixer looks as follows:
1. Measure the water in the right amount and pour it into a concrete mixer. Do not fill the water all, leave about 10% for later to bring the solution to the desired consistency.
2. Put cement in the right amount, leave a little cement.
3. Next, the sand is packed, followed by the process of mixing with each other of all components. It lasts about five minutes.
4. After preparing a cement mortar, add to it if necessary, a substance in the form of additives, plasticizers.
5. At the final stage, the filler is added. If the solution needs to add water, then it is mixed with cement, the resulting mixture is added to the concrete mixer at this stage.
All work is carried out for 10-15 minutes. If the entire solution was not removed at a time, then in the future it is constantly mixed until completely extracted.
Before making a concrete flowerpot with your own hands, we recommend that you paint the solution with color pigments. Modern technologies make it possible to make various concrete surfaces with colored and bright.
Pigments are added either at the stage of preparation of the solution or after the composition is hardened. There are two options for color pigments:
The color palette and saturation determine the chemical components of the pigment. It is recommended to add a pigment to the composition at the stage of kneading. In this case, it is possible to achieve uniform and beautiful color. In order for the color effect to appear on the surface as much as possible, we recommend using sand and white cement when preparing a solution.
Before adding a pigment, it is diluted with water. The quality of mixing affects the homogeneity of the solution. At the same time, such a composition is prepared exclusively in a concrete mixer. It is impossible to prepare a concrete solution with a manual method.
Before making a path from concrete with your own hands, it is also recommended to prepare a solution in a concrete mixer. This device allows not only to save time, but also significantly improves the quality of the finished solution.
In the process of filling the concrete solution, it is recommended to use a concrete vibrator. With it, it is possible to remove air bubbles and improve the quality of the finished coating. Additional reinforcement is provided by steel rods of reinforcement. The optimal setting time of the solution is about two days. The complete drying of the solution lasts about two weeks or more.

let's write to you better
let's better write you as it should. Pour a bucket of water into the mixer. Drink cement into a concrete mixer - everything is right, better than five hundredth and without additives (D0). To begin with a bucket, then you yourself will calculate everything. Plus a bucket of crushed stone and twist. Crushed stone - so that nothing sticks to the stirrer. It is important - a bucket of water on a bucket of cement, this provides an optimal water -cement ratio in weight 1: 1.7. Now add sand. Correctly, without clay and organics, large, a fraction of 0.3 ... 3 mm, this is exactly what is sold in a good place. The first difficulty - if the sand is moist, you need to take into account and subtract this water from that very bucket, What you flooded. Now - structural concrete - one bucket of sand. For the foundation tape - two buckets. For filling the planes - 3-4. Next, pour the second, third, etc. A crushed stone bucket. The more heterogeneous fractions of crushed stone - the better. It is not less than 10 mm and no more than a third of the characteristic minimum size of your design. Choose the amount of crushed stone yourself, the best rule: crushed stone lies tightly, the cement -thankled mixture only fills the voids between the gravel. The prepared concreterait should be, the abandoned shovel does not spread to the ground. Requires tamping. Typical errors: a lot of water; little crushed stone; not domestic; overflowed the mixer; In the vast majority of cases, excellent concrete per bucket of cement: a bucket of water, one and a half buckets of sand, 5 buckets of heterogeneous crushed stone. This is a brand above 300 (by concrete) .https: //vk.com/id1133295.
