Products made of reinforced concrete - profitable "designer" for construction

What is the secret strength of reinforced concrete products?

Reinforced concrete is a "platter" of two durable materials: concrete and steel.Reinforcing mesh all the penetrates inside the concrete "pie", shifting the blanking function "uncomfortable" stress in the system.If itself frozen cement-sand mortar can withstand the weight is fine, but is not able to resist the oppressive forces (bending), then paired with a metallic partner precast concrete product is easy to tolerate any extreme testing.

secret of ultimate strength w / w in the production constructions hidden features:

• Superior solution recipe. To make concrete use only select small gravel (10 mm), which is perfectly coexists with thick wire mesh.Admixture of small-bore - a guarantee of the absence of air "pockets" in the finished product.
• Additional steaming. drenched in blank form sent to the steaming chamber for 8-12 hours.This speeds up the cement hydration process, contributes to a better fusion of all components of the solution.
• voltage technology. Some types of concrete products (for example, floor slabs for the seismically dangerous regions) should have a particularly high rate of bending strength.For this purpose during their preparation tensioned reinforcing rods in the formwork with the jack (optionally heated electric) and in this position the concrete is poured, steamed oven.As a result, the finished element is able to withstand serious disruptions.
• Straining cement. This particular recipe is a mixture used for thin-walled reinforced concrete structures subjected to large power loads.The solution expands during solidification, as it were "swells" in its filled form truly pressure reaches record levels (up to 4 MN / m2).The material also used for the preparation of high-strength products from reinforced concrete with prestressed.

Symbol concrete - concrete products (concrete products).But as the range of elements from this material is constantly updated with new models, each of them has its own recognizable abbreviation.

«World" variety of concrete products

Here are the most prominent representatives of "concrete Dynasty»:

• plates to overlap.It - finished floors / ceilings for multi-storey building, the elements are the most popular "parts" in the construction.There are such kinds of floors: hollow (PC), whole (PTV), ribbed (ORT).In each of these groups has its own concrete products subgroups differing in the letter designations.
• Piles. This "feet" for the pile foundation, which are: precast (C) is pressed (IEDs), the screw (SW), shell (tube CT).Accordingly, each kind of element is in turn subdivided into several subtypes (e.g., rigid and articulated).
• Foundation blocks. used for the rapid construction of slab, bar or tape precast foundation.They are divided into wall (FBK), belt (PL and pillows), n-shaped (FSF) and the units with through holes (FB).The plant produces a massive elements (350 kg), and the "mini-cubes" for the unauthorized construction (30 kg).
• rings well. These products (K) - the basic building material for prefabricated w / b "reservoirs".With their help, you can quickly build a well of any type.
• Road plates.This web pavement for large runs and airfields (PAG, PDG).They are installed on those sections of the road, where it is assumed a particularly heavy weight loads.

addition to large-types of concrete products, there are a number of small products for any needs of construction.This paving slabs and paving stones, and walls to fence and curbs.

Explanation "code" of concrete products

In alphabetic abbreviation encrypted Concrete products: type, inner "filling" (density of reinforcement material) and the purpose of the element.But hidden its linear parameters in the digital code.Understand encryption scheme is pretty simple.

Consider a few examples:

1. equip the well of the w / w rings - CS-7-5.Hence used wall part 70 cm in diameter and 50 cm in height. As for its thickness, it is usually grouped elements of this indicator (8 mm, 10 mm, etc.).
2. construction of the foundation blocks FBS-6.4.12. We work with building blocks in length - 120 cm, width - 40 cm, height - 60 cm.

All variations of the legend of reinforced concrete products clearly stated in the SNIP.Each manufacturer in a directory is required to adhere to a common nomenclature, but additionally provides a table with a breakdown of the technical characteristics of the goods.
