In modern construction, natural materials are used and upgraded.Various mixtures of plaster composites.Particular attention cause materials used for walls and ceilings of buildings.Traditional bricks are replaced by lightweight concrete.What are they?What have the technical characteristics?Do not allow to freeze in the winter homes of the future tenants?In the summer?Do not let languish in the heat?Try to understand.
first time, a mixture of cement, large porous filler, sand and water experienced in the late nineteenth century.But to apply it in the construction began much later.Already in the twentieth century.Lightweight concrete also appeared decades later.To distinguish it from previous forms of the specific gravity.Technical terms, it should be no more than eighteen hundred kilograms per cubic meter.Only then the concrete is considered easy.To achieve this technical properties allows the presence of a part of expanded clay or slag.Accordingly, these types are called: expanded clay or slag concrete.But here also can be attributed to the excellent production, but have similar qualities of polymer concrete, foam concrete, polisterolbeton, aerated concrete.For what they produce and where to apply?The most common is the component of lightweight concrete slabs for the basement, first floor, attic.The reason is that such a partition of the heat capacity and, consequently, saving energy costs.
From usual heavy lightweight concrete has high porous qualities, low weight, heat saving.These types of building materials are indispensable in the construction of high-rise buildings.Lightweight concrete with porous aggregates, of course, inferior in strength properties.The question is easy to solve.They improve by inserting into the structure of reinforcement.
widespread lightweight concrete receiving lately in private construction.This is natural, by virtue of the material cost.According to its tasks in such works lightweight concrete is divided into two types.The first - the material for load-bearing walls with a porous filler, a specific gravity of more than one thousand four hundred kilograms per cubic meter.Call a concrete "constructive."Another kind and, accordingly, the brand - the thermal insulation.The name speaks for itself.Applied in the construction of non-load bearing walls.The weight of such material is not more than five hundred kilograms per cubic meter.
walls of buildings - not the only use for the lightweight concrete.They have proved themselves by pouring decorative forms.This contributed to the high-quality plastic.A lightweight concrete made competitive in the production of decorative products with heavy plaster.Columns, pilasters, rusty, cornices from the hands of masters out surprisingly elegant and original.
Light concrete, which meets all GOST standards - the perfect solution for private construction, the manufacture of fences, fences and other structures, involving the design intervention.
