Concrete Mixing by hand and in a concrete mixer

Instructions how to mix concrete, requires anyone who is building or making repairs.

After all, even the most modest building can not be effected without a foundation.

The main components of the basement of the building is concrete and rebar.

These components allow you to build a perfect architectural structures that can withstand extreme loads, strong wind and the vagaries of weather.

Concrete made from dry ingredients.

mixture without the addition of water can be a long time to keep the storage container closed.But before using the components of concrete, water is added.

hand made solution hardens in a few hours, so it is best to use it at once.Concrete foundation hardens, providing the strength of the base.

It should produce concrete with their hands in the construction of a frame house foundation and concrete stairs.

frame structures do not need the massive base, because they are not heavy weight.Just before that it is necessary to know how many and what ingredients you need.

concrete composition

main components of concrete solution - linking all the components of water and cement.They are complemented by gravel and sand.

cement powder made from ground limestone, chalk, gypsum and marl.Cement dust is harmful if inhaled, as is deposited in the lungs.

from contact with cement may cause irritation to the skin.Therefore, all the construction operations of cement is carried out in gloves, wearing a respirator.

of cement vary the strength, the higher the score, the higher the number in the name.

Popular brands - M400, M500.The volume of the components of these mixtures one to four and one to five - to one part cement is four or five parts of sand.

of natural raw materials - sand, classified according to the degree of granularity, it can range from 0.5 to 2 millimeters.

Sometimes in the sand next to the viscosity of the solution is poured a little clay.Sand with an excess of clay is required to be cleaned with water and dried.

Crushed granite is produced by grinding up the five millimeter particles.As for the concrete component solution, it must be washed, containing no clay and earth.

main condition for the water, which will go on kneading the mixture - purity.That is, it should not contain salts and acids that can change the characteristics of the solution.

That is why it is recommended to prepare on the basis of water from the aqueduct, and not from a well or a spring.

To improve the quality of performance peskobeton used additives.Some modifiers affect the plasticity and fluidity.

Others slow down the process of hardening, it is necessary in hot weather.Third - provide improved water resistance or protect against low temperatures.

Because of peskobeton depends the fate of all further construction, it is important to know how to use those components and in what sequence should they get mixed up in order to properly prepare a liquid formulation with his hands.

concrete preparation manually

Concrete pouring step of the foundation is very easy to make by hand, if you are small areas of construction.

plants producing mixes, do not bring to the site the product is less than one cubic meter of concrete.

The best solution would be to produce concrete with their hands when pouring occurs periodically, as happens in the formation of pile-foundation transom.

can also enroll in a great distance from the manufacturer and is unavailable travel to the construction site Automixers.

concrete manufacturing process for the foundation or other purposes with their own hands is not easy, so it is necessary to perform in parts, alternately mixing the ingredients.

To properly perform kneading by hand, you must first make a "ballast".It is important to calculate how to take ingredients.

Ballast made from stone chips and sand in a ratio of 3: 1.For one serving, you can take a bucket.

prepared for mixing deep container and a shovel.The old tub, which is available on all the suburban areas, fits in less than one cube, about 0.3.

But if the building size is small, would be enough pelvis and trowel.

1 part of cement and 5 parts of the ballast is connected to the container, stirring carefully and reaching mass uniformity.Basically proportioned data, but sometimes use only cement.

to concrete was the most durable, take the M500 brand cement.Of course, the higher the grade of cement, the more expensive it is.

If we talk about how much better to buy the cement, the bag 50 kg - the best option.

In the center of the resulting mixture, make a hole, pour into it a little water on the eye.Stirring is carried out on the container walls to the middle, where there is water.

Combining the dry mixture with water, you need to get to the bottom to thoroughly promeshat components.

After preparing the composition manually, pay attention to its consistency.If the proportions are chosen correctly, the solution will be liquid, but not fluid.

Too liquid mixture will lose strength properties.Excessive density also adversely affect the quality of construction.

consistency check is made easy.An edge of a shovel to cut a small section of the concrete square shape.Then watch it faces.If they do fall apart, then water is added little.If

through the concrete structure, made with his own hands, trickling water, then it is too much.It is necessary to further mix with concrete and make it to the composition, again mix thoroughly cooked before.

Note: Water is poured into the prepared powder mixture.This sequence of actions when mixing sand concrete with their hands to prevent the appearance of lumps.

Concrete proper consistency should easily rise from the shovel capacity and not uproot with great effort.

At the end make much of the need to improve the properties, the plasticizers and rubble.Hand made concrete solution is delivered to the construction site in buckets.

In the case of large-scale construction, manufacturing peskobeton manually becomes exhausting process.

quickly, without wasting power, you can get the concrete in a concrete mixer.

concrete mixer Production in

Now there are a lot of cars that can facilitate the production of concrete.Simply prepare a composition in a concrete mixer, than to manufacture its parts with large volumes of construction.

How much material is needed?If the proportions translate into kilograms, then cube peskobeton need 300-350 kg of cement.

Also popular cube building materials spend sand - 600-700 kg, gravel - 1100-1200 kg, and the water - 150-180 liters.

The difference is explained by unequal proportion of each quality ingredients.For example, gravel chippings characterized by a higher measure of strength, rather than limestone.

That is why it is commonly used in a smaller proportion.

To make a cubic building materials, easier to use buckets.If pour buckets of components, it is necessary to know that they do not have the same weight.

For example, in one bucket cement weighs about 16 kg and gravel - about 17 kg.So, measuring out the proportions in buckets, based on the ratio: 9 parts gravel, 5 - sand, 2 - cement.

solution is prepared in a concrete mixer correctly follows.The bulb of this device is set at a 45-degree angle.Poured into the sand.

Cement is loaded into the mixer gradually, including the mixing mechanism after another addition.

After connecting to the mixer sand and cement is poured into water in portions.By adding a little quantity of water, scroll mixer.

next component to be added to the weight of a concrete mixer - rubble.It is also necessary to make small batches for uniform mixing.

Although the manufacture of construction products in the mixer can be a bit away from the strict sequence of mixing procedures, as in the work of their own hands, but always keeping all proportions.

Tolerated simultaneously lay the instrument all the ingredients: half a bucket of water, four buckets of gravel and one bucket of cement.

not stopping the progress of the batch, made up two buckets of water.The solution is to scroll to the mixer a couple of minutes.The consistency of the prepared concrete compared with liquid clay.

Other options

If you realize that your own hands you prepare the groundwork for pouring the foundation frame house or other small structures fails, then resort to the help of professionals.

not puzzling over how much to take and how their components to mix, you can buy a cubic meter of concrete, which should be enough for a small building.

Cube this building product is from 2400 rubles.This figure concerns the lowest mark.Cube brand medium strength (M400) is from 3200 rubles.The most expensive and reliable brand - M600.

Cube such concrete would cost 4 thousand.
