(57) Abstract:Proposed fillers, including bone glue, soap, chalk powder, water. Additionally, it contains 30% solution of waste expanded polystyrene in a mixture of acetone, petrol a-76 at 1:1 ratio. Putty is designed for leveling concrete and plaster surfaces. The technical result is the improvement of the water resistance and adhesive strength of the filler, and a shorter drying. table 2. The invention relates to compositions of filler, used for leveling concrete and plaster surfaces.Known fillers, including bone glue, chalk powder, soap, varnish-oksol and water (TU 21-53-66. The adhesive putty).Closest to the technical essence and the achieved result is the composition [and.with. N 796218, M CL C 04 B 25/02], including weight.h.:
Ground chalk - 100
Soap - 2,3-8,0
Glue bone - 3,5-9,0
Deficit - 10,0-50,0
Water - 45,0-65,0
The organic additive is 2.0 - 25,6
As organic additives used drying oil-oksol, or a mixture of drying oil-oksol with emulsol sour synthetic with their weight ratio respectively of from 1:0 to 0.2 to 0.8.The purpose of the invention is the improvement of the water resistance and adhesive strength of the filler, and a shorter drying.This objective is achieved in that the fillers, including bone glue, soap, chalk, water, optionally containing 30% solution of waste expanded polystyrene in a mixture of acetone, petrol a-76 at 1:1 ratio in the following ratio, wt.%:
Glue bone - 1,5-2,0
Soap - 1,0-1,5
30% solution of waste expanded polystyrene in a mixture of acetone with gasoline in a ratio of 1:1 - 22-27
Water - 10-15
Chalk - 55-65
Waste polystyrene foam are used EPS packaging.Putty is prepared as follows: in separate containers prepared solution of bone glue and soap business, the resulting solution poured into the emulsion basis and mix, then add small portions 30% solution of polystyrene and mix thoroughly until a homogeneous mass. The resulting emulsion is diluted with the remaining water and enter a chalk, mix thoroughly, and then fray in kraskoterke, and then loaded into containers for the finished product.Examples of the composition of predlagaemiy in table. 2. Fillers, including bone glue, soap, powdered chalk and water, characterized in that it further contains 30% solution of waste expanded polystyrene in a mixture of acetone with gasoline in a ratio of 1 : 1 in the following ratio, wt.%:
Bone glue - 1,5 - 2,0
Soap - 1,0 - 1,5
30% solution of waste expanded polystyrene in a mixture of acetone with gasoline in a ratio of 1 : 1 - 22 - 27
Water - 10 - 15
Mel - 55 - 65p
FIELD: building materials, in particular new artificial stone.
SUBSTANCE: claimed stone contains 25-75 vol.% of inorganic filler and resin. Stone has coarse surface with uncovered inorganic filler, wherein average depth of downward grooves is 0.02-1.0 mm. Stone of present invention has complex structure, is massive to the feel and has clear, deep, and marble-like color. Moreover stone has high surface hardness, good formability, and excellent nonslip properties being in contact with bare feet and hard footgear sole.
EFFECT: improved artificial nonslip stone for floor manufacturing.

FIELD: building, particularly forming coating on sport ground and similar structures.
SUBSTANCE: method involves securing vertical rods in load-bearing layer, arranging zigzag heating wires connected with power source on load-bearing layer; connecting heating wires to vertical rods and applying coating material on load-bearing layer. Coating material is concrete of the following composition (% by weight): low-molecular oligodiene - 8-11; sulfur - 3-6.5; thiuram - 0.3-0.7; zinc oxide - 1.5 - 5.0; calcium oxide - 0.3-0.6; ash from heat power plant - 7-10; remainder - quartz sand. Uninsulated heating wire is used as coating layer reinforcement. Rod height corresponds to coating layer thickness. Electric power is supplied from power source for 55-56 min to obtain coating layer temperature of 85-95°C and then for 180-200 min to maintain 115-125° temperature thereof. Rate of temperature change may not exceed 1°C per minute.
EFFECT: reduced power inputs along with increased coating strength.
