Comparison of prices for independent and factory production of concrete.

For those who are interested in what constitutes a concrete mix, it will be useful to read the following. So, concrete compounds are cement, sand, water and rubble. In addition, various impurities can be added to this mixture, which contribute to greater strength or hardening of the concrete.

If we are talking about a class or brand of concrete, then everything is determined by the proportion of the components of the concrete mixture, as well as the amount of plasticizers and various chemical additives that may be contained.
And yet, what for in concrete it is necessary to add sand and crushed stone? If the cement is diluted with water, a very strong stone is already formed. The problem is that such a stone is very inclined to crack and sag. In this case, sand and gravel are the role of the structural skeleton, which helps to amortize and mitigate the situation. In addition, the addition of sand and gravel helps to reduce the cost of concrete mix. However, it should be noted that the rubble should be twice as strong as the concrete grade.

Self-made concrete

Often there are situations when the purchase of ready-made concrete does not solve all the problems of construction. It often happens that the concrete mix has to be cooked right on the construction site. This is usually done for casting of some reinforced concrete structures, stairs, screeds, etc.

Let's consider a number of situations for which independent manufacture of concrete may be required:

• A small amount of concrete is needed. The minimum quantity of concrete mix delivery usually has standard sizes of about 4-5 cubes.
• In the event that concreting occurs gradually at intervals in operation. This can be associated with pouring multi-tier reinforced concrete structures, individual crossbars, etc.
• The passage of special equipment to the object is difficult.
• The building is located far from the factory where concrete is made. In this regard, prices for concrete with delivery can be very disadvantageous to differ from simple prices for concrete.

It is worth paying attention to the fact that homemade concrete may not be so cheap.

The proportion of concrete, its cost and manufacturing process.

Let's try to count how much can cost concrete produced at home. So, to make one cubic meter of a concrete mixture of medium grade, we need:

• 300-350 kg of cement - 1100-1200 rubles. Also, the transportation of cement can supplement another 300-500 rubles.
• It is impossible to do with a small amount of sand, because Small volumes can not be transported. Therefore, with transportation, you should immediately count on 5000-6000 rubles. One cube will cost 500-700 rubles.
• The same story will be repeated with rubble. The minimum batch of crushed stone is 4-5 cubes. For one cube it is possible to give 1300-1400 rubles.
• And finally you can not worry about the water. It will take about 150-180 liters, which you can get almost for free.

In addition, it is also important to pay attention to raw materials. It can radically change the cooking formula.

In total, the components for mixing concrete can cost us 3100-3500 rubles. This will be the final price, if not include the use of labor.

The factory concrete with delivery will cost approximately 2600-3000 rubles. It is worth considering whether this game is worth the candle! Of course, in some situations this can be much more convenient, however, professionals in the manufacture of concrete have much more experience and technology to create concrete mixtures. Professional technology allows you to minimize costs and offer concrete at a much more affordable price.
