Concrete – parent material which is used at construction for creation of designs. In many respects, as far as objects from it will be strong, exact respect for technology of laying, on what surface and at what temperature concrete is poured depends.
Instruction
1. First of all it is necessary to prepare surface on which will pour concrete. Clean it from dust, dirt and garbage. If it uneven, then at alignment to you can to be necessary shovel or pick hammer. Also it is necessary to remember that crushed stone for concrete preparation has to be clean too.
2. On the prepared surface establish timbering in which concrete will be directly filled in. It can be wooden or iron. If you have made it of tree, before bookmark surely moisten boards with water that moisture from concrete was not absorbed in tree. The timbering from iron does not need to be moistened.
3. There are three ways of laying of concrete: with consolidation, casting and basic laying. Casting can be used when the concrete mix contains supersofteners. Usually concrete is poured horizontal layers in one direction to fifty centimeters in height. Concreting process ideally has to go continuously that layinHow to pour concrete

Usually concrete is poured horizontal layers in one direction to fifty centimeters in height. Concreting process ideally has to go continuously that laying of each subsequent layer began until as previous will begin to dry up. At construction jobs of big scale it is impossible to avoid breaks in laying of concrete therefore construction joints in places where they will not influence durability of all design become.
4. In order that concrete was more dense, it is condensed by means of electric vibrorail. Its fluctuations give to concrete big fluidity, possible rassloyka of concrete are liquidated, and it becomes stronger and strong.
5. Concrete right after laying is covered with dense fabric which is moistened and supported in damp state until concrete does not grab. After the expiration of ten days the timbering can be removed. And overall load on concrete structure can be carried out only after full hardening of concrete.
