Abstract

FIELD: construction.

SUBSTANCE: filler for concrete is made in the form of grain of round shape, having a cavity 3, formed by means of adhesion of two parts 1 and 2, made from clayey raw materials by moulding with subsequent baking, with a porous body 4 placed in the cavity 3, produced in process of baking of adhered parts 1 and 2 by foaming of foam glass charge including the following components, wt %: ground silicate glass 93-97 and gasifier - chalk or marble or coke 3-7, besides, at least one of parts is perforated 5.

EFFECT: production of a light strong filler having heat insulation properties, simplified technology of its manufacturing.

Description

The invention relates to the production of aggregates for concrete.

Known aggregate for concrete, made in the form of round-shaped grain having a cavity formed by gluing two parts made of clay raw materials by molding with subsequent firing, with a porous body placed in the cavity [1].

The objective of the invention is to simplify the manufacturing technology of aggregate.

The technical result is achieved by the fact that in the aggregate for concrete, made in the form of rounded grains, having a cavity formed by gluing two parts made of clay raw materials by molding with subsequent firing, with a porous body placed in the cavity, the porous body is obtained by firing the glued parts the foaming of a foam glass charge, including, wt.%: ground silicate glass 93-97 and a blowing agent - chalk or marble or coke 3-7, and at least one of the parts has perforation.

Figure 1 shows a placeholder for concrete.

The aggregate for concrete, made in the form of round-shaped grain, consists of parts 1 and 2, forming when connecting the cavity 3, in which the porous body 4 is formed, formed by firing the glued parts by foaming the foam glass charge in the cavity. At least one of the parts has a perforation 5, for example, with round holes.

Prepare a foam glass mixture, table 1.

On the basis of clay raw materials, plastic parts or semi-dry molding produce parts 1 and 2 of rounded grain. In one of the parts (preferably without perforation), a foam glass charge is poured. The parts are glued together with a ceramic slip, imposing a part with perforation 5 on the part filled with a foam-glass charge, and firing (firing temperature 850-1100 ° C). During firing, the foam glass charge foams and forms a porous body 4. In the cavity 3, the gases formed during foaming exit through the perforation 5.

Aggregate (of various sizes, for example, 50-200 mm) is not difficult to manufacture, lightweight, durable, has thermal insulation properties.
