Abstract

Invention applies to the construction industry. The invention aims to improve the thermal properties and strength. The proposed material consists of the following components, in mass percentage: lime 5-17; amorphous silicon dioxide 11-25; cement 0-13; structure forming additives ( natural gypsum or phosphoric gypsum, iron waste of the silicon production process, liquid glass, reinforcing fibre, plasticiser, hydrophobic additions) 0,5-11; pigments 0.2-4; water 0-83. The mass consisting elements are mixture, mixed to form a homogeneous mixture, then poured into forms and put into a steaming chamber or autoclave for a 3 hour hydro-thermal hardening in 90-180 degrees Celsius. Articles taken out from the forms are dried in a 120 degrees Celsius temperature. Materials (concrete, mortars) are distinguished by their high thermal properties and strength characteristics.

The mass was stirred until homogeneous. Subsequently, II g of amorphous silica-perlite was added to the mixture and stirred until a homogeneous mixture was obtained. The so prepared mass was poured into sealed molds, which were placed in a firing chamber or autoclave for hydrothermal curing at 90-180 ° C for 3-8 h. The molded cured articles were dried at I20 ° C or ambient temperature.

Kaip matyti iš pateiktų 2 lentelėje duomenų, gaminių iš pareiškiamos medžiagos šiluminės savybės ir stiprumo charakteristikos žymiai geresnės už gaminių iš žinomos medžiagos charakteristikas. Esant 300 kg/mr betono tankiui gaminio iš pareiškiamos medžiagos šilumos laidumo koeficientas 0,064(7 pavyzdys), iš žinomos - 0,08 (18 pavyzdys). Esant 600 kg/m betono tankiui, gaminio iš pareiškiamos medžiagos šilumos laidumo koeficientas 0,109 (II pavyzdys), iš žinomos - 0,13 (19 pavyzdys). Taip pat palyginus gaminių iš pareiškiamos medžiagos ir žinomos stiprumo rodiklius, matosi, kad gaminių iš pareiškiamos medžiagos stiprumo rodikliai, esant tam pačiam medžiagos tankiui, geresni (pavyzdžiui, II, 19 pavyzdžiai).As can be seen from the data presented in Table 2, the thermal properties and the strength characteristics of the articles made from the claimed material are significantly better than those of the known material. At a density of 300 kg / mr concrete, the thermal conductivity coefficient of the product of the claimed material is 0.064 (Example 7), of the known - 0.08 (Example 18). At a density of 600 kg / m of concrete, the thermal conductivity coefficient of the product of the claimed material is 0.109 (Example II), of the known - 0.13 (Example 19). Similarly, comparisons between articles of the claimed material and known potency show that articles of the claimed material have the same strength at the same material density (e.g., Examples II, 19).
