The preparation of concrete and the secrets of its quality

Concrete mixing can be carried out manually and by using mixer. When you need to cook a small amount of the mixture, it is best to mix by hand.

In order to measure the right amount of materials, it's best to use two large buckets. One of them must adapt to the cement, and the second to use for sand and coarse aggregate. Shovel is most convenient to use two.

The Preparation of concrete by hand requires maximum accuracy when measuring the quantity of ingredients. It is better to keep the level under the bucket rim. When filling of the tank with cement or sand to seal the loose particles, while tapping on the side wall. To mix material better shovel.

As for the mechanical method, the preparation of concrete in this case involves the use of concrete mixers of cyclic action, which differ in the method of mixing the components of the ingredients.

The Mixture in the mixer should be stirred for several minutes. Then you need to tilt the mechanism to pour a little of the mixture in the wheelbarrow, checking thus her readiness. The drum thus to stop is not worth it.

If you need to learn how to carry out the preparation of concrete for the Foundation, you should be familiar with this in detail. So, as the filler is better to use gravel or sand. The proportions are as follows: sand-cement 3:1 sand-gravel - 3 (4):1. As for water, it should be added with extreme caution. The fact that the concrete which is the most optimal for the construction of the Foundation should be plastic. Because the material is placed, but not filled. Therefore, the higher the degree of hardness, the stronger will be the Foundation in the result.

Note that if you prepare the concrete using wet materials (after rain, for example), then you should know that they already contain about 20% of the fluid. Therefore it is necessary to add only 80%, not 100%.

Note that in the production of concrete is of great importance to the shelf life of the cement. The longer it is stored, the lower its grade, which automatically reduces the quality of concrete.

The Preparation of concrete requires proper storage of materials. So, if you have sand, it must be stored in the same container in which you purchased it. Loose components should be kept separate from each other, and need to put them on a hard surface or thick plastic sheeting. And on top of the pile should be covered with the same film and secure the cargo.

Storage of cement requires compliance with more stringent conditions. So, paper bags with this component need to be put on a pallet that is placed on the bars. Thus they will not touch the ground. The most optimal place to store – a dry shed or garage. If it is not possible to place the cement in the room should be covered with plastic wrap and affix the bricks. If the package of cement is not fully used, the remainder should be put in a plastic bag.

To date, the preparation of concrete is not always possible at home, because there is in the sale of ready-mixed concrete mixture. As a rule, it is used in cases when you need large quantities. It is necessary to unload directly next to production, then to not carry the mixture into the wheelbarrow. However, if unloading takes more than an hour, the provider may incur additional charges.

Today, there are a number of companies, preparing the mixture on the spot and bring individual ingredients. You just have to move the concrete and pour it. In this case, leaves no waste, and pay only for the used amount of material.
