SU1224290A1 - Compound for finishing work - Google Patents

Description

The invention relates to construction materials, in particular compositions used in the manufacture of finishing works in construction.

The purpose of the invention is to increase the viability, biostability and reduce shrinkage.

The invention is illustrated by the examples given in table. one.

The carbonate filler is solid waste soda ash, which is obtained from a distiller suspension, which is a mixture of liquid and solid phases and is a waste product. Distiller suspension is discharged into dump tanks, where, as a result, sludge is separated into liquid and solid phases. The liquid is carbonized and pumped into the oil reservoirs, and the solid phase accumulates over a long period, forming a solid production waste of the following composition,%:

Mass fraction of carbonates of SaCo. and MgCO not less than 55

Mass fraction of chlorides, Cf not more than 7 Mass proportion of moisture, not more than 35 Mass fraction of alkalis in terms of

on, not more than 2

Sulphate content 50, not more than 8

Solid wastes of this composition are dried at 120-150 0 and grind in hot form, as a result of which a solid waste of soda ash production of the following composition is obtained, wt%:

This solid waste from soda ash production is used as a filler in the finishing composition.

As a hydrophobic plasticizer in the construction mixture, monohydric alcohols of the fraction 5 bottoms from the production of monohydric synthetic alcohols are used, representing a light yellow paraffin-like mass with a melting point of 60-75 s.

The preparation technology of the proposed mixture is as follows.

A certain amount of solid waste from the production of soda ash with t 90-110 0 is loaded into a ball mill at the same time. The calculated amount of the alcohol fraction is loaded there,. Grind and mix simultaneously. these components, resulting in a hydrophobized solid waste production of soda ash.

Alternatively, the calculated amounts of water, 10% aqueous solution of bone glue, drying oil, and household bag are loaded into a porcelain cup, having a paddle with a rotational speed of 400-500 rpm. The mixture is stirred for 5-7 minutes until a homogeneous mass. Next, the hydrophobic solid waste from the production of soda ash and the mixture obtained in a porcelain cup are mixed and ground in a mortar for 5-6 minutes, and the finished composition is placed in a container.

Physico-mechanical properties of the proposed and known compositions for finishing works are given in table 2. 0

The proposed composition has good workability and grindability. Replacing chalk in the proposed composition with a production waste not only expands the resource base, but also reduces the cost of finishing work.
