The invention relates to the manufacture of building materials and can be used to commission lightweight aggregate pellets.

The purpose of the invention is to reduce the labor intensity of manufacture.

The lightweight aggregate includes a core made of fibrous material and a reinforcing sheath, the core being made from an osprey of pulp and paper production, and the shell is made from a mixture of cement and glass and soluble glass and ash.

Osprey appearing. pulp and paper production, in the process of artificial or natural drying, due to the sacking properties and the presence of flocculation in it, is compacted and spontaneously turns into granules of various sizes, having various particle shapes, which can be crushed to desired sizes if necessary. The dry granulated scopes without reinforcing and protective coatings are characterized by a bulk bulk density of up to 190 kg / m and compressive strength of 1-1.2 MPa.

The filler is made as follows.

EXAMPLE 1. Water is poured into a concrete mixer and clay is charged in equal quantities by volume and the mixture is stirred to obtain a clay slurry with a bulk weight of about 1,400 kg / m, which corresponds to Waste-g, mix mixture cement 1. that and clay

about 700 kg of clay per 1 m of suspension, calculated on dry clay.

Then a clay suspension is loaded into the concrete mixer and the cement is thoroughly mixed with the addition of water in an amount necessary to obtain a solution of the required consistency. After the cement clay solution is obtained, the dried osprey granules with a bulk density of 190 kg / m are loaded into the concrete mixer and the mixture is mixed so that the cement clay mortar covers the entire surface of the granules. Osprey granules coated with cement-clay mortar are discharged from the concrete mixer and then dried in a drying chamber, after which their properties are examined.

Example2. The concrete mixer is loaded with a glass-ash paste, which is prepared from liquid glass, TES fly ash and water, taken in a ratio (wt / h), respectively, 1: 1.2: 0.3. Then, dried osprey granules are fed into the concrete mixer and the mixture is mixed so that the glass-ash paste covers the entire surface of the granules. Osprey granules coated with paste are unloaded from the concrete mixer and dried in a rotating drum at 150 C. The dried osprey granules are unloaded from the drying drum and their characteristics are determined.

Indicators of the properties of the obtained aggregate in examples 1 and 2 are presented in the table.
