Description

4: OS O5 O1 The invention relates to the building materials industry and can be used in the development of autoclaved products. It is known that products for autoclaving hardening f 1 T, t include quartz sand and the product of burning carbonate-sand mixture, having the following phase composition, wt.%: С2555-75; СаО1О-35 | 5ip2 5-15 | other minerals up to 3. The closest to the invention according to the technical essence and the achieved result is a sticking for manufacturing, autoclaved hardening products, including; wt.%: quartz sand 41-68 and carbonate calcination product “—sweed bath mixture 32-59, with the next calcination product, weight,%; dicalcals. evium silicate 50-75; Sodium and potassium aluminate 5 {oxide calysus 10-12 j sodium ferrite and potassium 3-7 J impurity O, O8-2. The disadvantage of these people living is low strength, the purpose of the invention is to increase the strength of tee. what is meant for the manufacture of autoclaved hardening products, including quartz sand and the product of burning carbon-silica-silica mixture, contains the product of burning carbonate-silica mixture having the composition, wt.%: oxide 32-45}. three-calcium silicate 8-16 J dicalcium silicate 25I calcium aluminoferrite 10-14 with the following the ratio of components, wt.%: Quartz sand 40-60 The product of burning carbonate-silica mixture 40-6 О Example, To obtain a binder, three mixtures of chalk and flask of a hydraulics module 2.65.3.0 and 3.6 are prepared, the mixture is ground to a residue on the sieve No. O08, equal to 8-10% and calcined by Szcc 1230 ° Co. The calcining product is ground together with quartz sand in the ratios: 40; 6O, 50: 5O and 6O; 4O to the specific surface 6OO-7OOO on samples-beams of 4) g size 4 X 16 cm, which are molded from a mixture containing permeable and -normal n ekok (GSH: T 6139-70) in a ratio of 1: 3. Compaction of the mixture in the forms is carried out on a laboratory vibrating plate using a static load of 50 g / cm. Samples are subjected to hydrothermal treatment in an autoclave according to the 3 + 8 -t mode for 3 hours at a pressure of 8 agm and are tested for compressive strength and bending. The data obtained are given in table. 1, which shows the indicators of the known to the merchant. The compositions and properties of the pro-totem are presented in Table. 2. Thus, the proposed tiller has greater strength than the well-known. T a b p and p a 1
