Abstract

Sposób wytwarzania betonu komórkowego o zmniejszonej gęstości objętościowej i zwiększonej izolacyjności cieplnej charakteryzuje się tym, że w ustalonej kolejności wprowadza się grawitacyjnie surowce i półprodukty do mieszarki turbinowej o pojemności 5 m3. W pierwszej fazie jest to szlam piaskowy z wodą w ilości 1000 - 1600 kg wraz ze szlamem odpadowym i częścią 2,5 - 4 l środka powierzchniowo czynnego, które miesza się, po czym dodaje się wapno palone mielone o zawartości całkowitych i aktywnych tlenków wapnia CaO > 90% w ilości 10 do 20 kg/m3 i miesza się, następnie dodaje się cement portlandzki: 42,5 w ilości 20 - 40 kg/m3, cement portlandzki 52,5 w ilości 10 do 20 kg/m3 oraz mączkę kwarcową o zawartości SiO2 min 94 - 97% w ilości 0,5 - 1% w stosunku do masy ogólnej cementu i miesza się, po czym dodaje zawiesinę proszku Al 8 - 9,5 l/m3, który pozostaje wymieszany z roztworem wodnym środka powierzchniowo czynnego w proporcji 3 : 1, po czym po zbilansowaniu cieplnym masy zarobowej, podaje się ją do wysmarowanych olejem form, następnie prowadzi proces uszlachetniania i dojrzewania w komorach do wyrośnięcia i uzyskania wytrzymałości w skali 3 - 6. Na koniec prowadzi się rozformowanie form i dalszą obróbkę bloku masy do uzyskania wymaganego kształtu i wymiaru oraz formatuje wyrób, który transportuje się na stanowisko separacji wyrobów, na którym oddziela się każdą kształtkę w linii cięcia wzdłużnego, po czym produkt wraz z dnem hartowniczym wprowadza się do komór grzewczych o temperaturze 80 - 90°C, po czym poddaje się procesowi obróbki hydrotermicznej i procesowi paletyzacji oraz pakowania wyrobu końcowego.The method of producing aerated concrete with reduced volumetric density and increased thermal insulation is characterized by the fact that raw materials and semi-finished products are fed in gravity to a 5 m3 turbine mixer. In the first phase, it is sand sludge with water in the amount of 1000 - 1600 kg together with waste sludge and a part of 2.5 - 4 l surfactant, which is mixed, followed by the addition of ground quicklime with the content of total and active CaO calcium oxides > 90% in an amount of 10 to 20 kg / m3 and mixed, then Portland cement is added: 42.5 in an amount of 20 - 40 kg / m3, Portland cement 52.5 in an amount of 10 to 20 kg / m3 and quartz flour with SiO2 content min 94 - 97% in an amount of 0.5 - 1% in relation to the total weight of cement and mixed, after which a suspension of Al 8 - 9.5 l / m3 powder is added, which remains mixed with the aqueous solution of the surfactant in 3: 1 ratio, after which, after balancing the working mass, it is fed into oil-smeared molds, then the refining and maturing process takes place in the chambers to grow and obtain strength on a scale of 3 - 6. Finally, the molds are demoulded and further processed a block of mass block to obtain the required shape and size, and format the product, which is transported to the product separation station, where each profile is separated in a longitudinal cutting line, after which the product together with the hardening bottom is introduced into heating chambers at a temperature of 80 - 90 ° C, after which it undergoes the hydrothermal treatment process and the process of palletization and packaging of the final product.
