Preparation of concrete can be done by hand and with the help of a concrete mixer.When you need to cook a small amount of the mixture, it is best to mix everything by hand.
In order to measure the right amount of material, it's best to use two large buckets.One of them must be adapted to the cement, and the second used for sand and coarse aggregate.Shovels convenient to use two.
Preparation of concrete by hand requires maximum precision when measuring the number of ingredients.It is better to make sure that the level was under the vedernoy border.When filling the container with cement or sand should be compacted loose particles, tapping the side wall.Mix the material best shovels shovels.
Regarding the mechanical method, the preparation of the concrete in this case involves the use of concrete mixers cyclical actions that differ in the way of mixing the components of ingredients.
mixture in a concrete mixer has to stir for several minutes.Then you need to tilt mechanism so as to pour a little mixture into a wheelbarrow, so check its availability.The drum is thus not worth it to stop.
If you need to learn how to carry out the preparation of concrete for the foundation, should be familiar with these details.Thus, as a filler better use rubble or sand.The proportions are as follows: sand-cement - 3: 1, and the sand-gravel - 3 (4): 1.As for water, it should be added with caution.The fact is that the concrete, which is optimal in the construction of the foundation must be ductile.Because the material is placed, but not filled.Because the higher the hardness, the stronger will be the foundation as a result.
Note that if you prepare the concrete with wet materials (after the rain, for example), then you should know that they already contain about 20% of the liquid.Because it remains to add only 80%, not 100%.
Note that in the production of concrete is crucial term storage of cement.The longer it is stored, the lower the grade, which automatically lowers and the quality of concrete.
preparation of concrete mix requires the appropriate storage of materials.So, if you still have sand, it must be stored in the same container in which you purchased it.Loose components must be kept separate from each other, and they must be placed on a hard surface or thick polyethylene film.And on top of the pile must be covered with the same film and secure the cargo.
storage of cement requires compliance with more stringent conditions.For paper bags with this component you need to put on a pallet, which is posted on the bars.Thus they are not touching the ground.The most optimal storage space - a dry shed or garage.If it is not possible to place cement in the room, it should be covered with plastic wrap and secure with bricks.If a packet of cement used is not completely, the remaining part should be put in a plastic bag.
To date, the preparation of the concrete is not always possible at home, because there is a sale of ready mixed concrete mixture.Typically, it is used in those cases where a large amount thereof.To unload it must be directly next to production, so you do not carry the mixture into a wheelbarrow.However, if the unloading takes half an hour, the supplier may require an additional charge.
Today, there are a number of companies that prepare the mixture on the spot and bring with them the individual ingredients.You just have to carry the concrete and pour it.In this case, it is leaving no waste, and pay only for the amount of material used.
