How to pour concrete
If you have decided to build a small structure on your land, you definitely need to know how to pour concrete. since this material is used for installation of foundations of the future building.
To get you started,you will need to purchase a sufficient quantity of cement and sand. In itself, concrete is a cement-sand mortar, mixed in certain proportions. As a rule, to fill the foundation use the ratio of cement to sand 1: 4.
When you buy cement be sure to pay attention to its brand, which should not be below 500. To calculate the necessary amount of cement and sand, it should be taken into account that 4 bags of cement are needed to produce one cubic meter of solution. Be very careful when calculating.
Before preparation of a solution necessarily as should sift the sand. You can use special construction sieve with cells, the size of which is not more than 10x10 millimeters. If you do not have such a sieve, you can use the grid from the old bed, which you need to install vertically. Then just throw a shovel on the net sand. Thus, a mound of sifted sand will form from the back of the mesh.
The solution should be mixed in a large container in the vicinity of the pit, which will need to dig for installation of the Foundation. Otherwise you will take for a concrete pouring a lot of time. because you have to carry it in buckets from the tank to the pit.
If possible, we recommend to use special mobile concrete mixer. which can be found in any construction shop or rented. Such devices are very convenient in operation, as they are easy to transport and tilt to pour concrete into the pit.
We should also talk about reinforcement. For Foundation definitely need to use rebar. which use a special rod or steel wire with a large cross-section. In addition, for reinforcement you can use practically any metal objects: angles, pipes, rods, channels and so on. Particular attention should be paid to reinforcing the corners, since this part of the foundation should be strong enough. Otherwise, chips will appear at the corners. The reinforcement must be stacked step by step: first one layer of the foundation with reinforcement is poured, and then a new one is applied.
You should not be afraid to pour a lot of water into the pit.Thanks to water, the solution will become denser. that will allow him more firmly and securely fit rebar of the Foundation. After the last band filled the layer, you need to top to fill a small layer (1-2 mm) of dry pure cement. Now we need to wait until the Foundation is completely dry, you can then go to the upload cap.
As you can see, to pour concrete for the Foundation is not so difficult as it might seem at first glance. The main thing — the presence of a sufficient quantity of cement, sand and water, as well as the necessary tools. In addition, it is better to perform this work independently, and to call one or two people. The fact that the sifting sand and mixing mortar are quite lengthy and time-consuming procedure. However, if you are sure that you will be able to complete all the steps, we recommend you to seek help from professionals .
Accidentally came to your article, after reading which I would like to note and add a few points: 1 in the composition of concrete on past cement, sand and water also includes crushed stone and sometimes includes various additives. 2 Water in the concrete mixture must be added in strict accordance with the instructions on the bag, excess water reduces the strength of the cement. But in the pit it does not need to be poured completely. 3 Four bags of cement for a cube of concrete are too small to get a normal concrete you need at least 8 bags, and the cement must be a good proven manufacturer, for example, I usually take Master Wagon (Lafarge) or Holmes. 4. Cement can be taken and the 400th, if it is good, just a little the proportions will change.
Good afternoon, tell me a good channel or video hosting for construction. Very necessary.
