4. Preparation of the blend CELLULAR CONCRETE MONOLITHIC GROWING autoclave resistant.

4.1. The materials used for solution of non-autoclaved aerated concrete monolith rising water resistant must have a minimum temperature of + 5 ° C, and water - not more than + 70 ° C.

4.2. Cement and pore-forming dry mixture should be stored in closed warehouses exclusion of moisture.

4.3. The solution was autoclaved aerated concrete monolith rising water-resistant mortar mixer is manufactured in a high volume from 0.5 to 0.1 m3. The volume of mortar depends on the desired output of the production line.

The mixer must be easy to navigate to the place fill forms at the factory and to place fill in the formwork to the construction site.

4.4. Dosing binder at work on a building site is on the mass by weighing in special tanks at trade balance.

4.5. To simplify this process by using cement, supplied in standard kraft bags (50 kg.) Of kneading (depending on the type of beverage prepared autoclaved aerated concrete monolithic waterproof increasing density) is set so that the flow binder it is a multiple of 50 kg. In this case, a bag of cement is placed on the upper grille installation equipped with a special device such as a "blade" torn paper and binder fed into the mixer. In the factory, the manufacture of blocks or other products dosing by weight of the binder is performed in the standard weight doses.

4.6. The dry mixture is blowing agent is dosed by weight, by weighing in a special container on the balance of trade.

4.7. Water when working on site dosed by volume ottarirovannoy measuring container. This may be used conventional buckets of 10 - 15 liters. In the factory, the dosage of water is carried out by mass using a standard weigher.

4.8. Loading components for preparing a solution of autoclaved aerated concrete monolithic growing mortar waterproof working in the construction site in factory conditions in the following sequence: First, the mixer is supplied metered amount of water, and then turn on the installation and vigorous stirring loading mortar cement mixed solution 10 to 20 minutes. Further, the stirred solution was added carefully measured quantity of dry pore-forming mixture and stirred for 30 - 60 seconds to obtain a liquid (liquid cream consistency) of homogeneous structure. In the process of mixing the components of the solution should be a visual inspection for its unity.

4.9. The prepared solution aerated autoclaved concrete monolith rising from the mixer waterproof special sleeve, mounted in an outlet in the bottom of the mixer is poured into the prepared pan (at the factory) or poured into a specially prepared shuttering any form (the construction site). Sleeve sinks to the bottom and gradually form as a mixture of filling it moves upward along the shape. As formwork can use plywood or use of reusable formwork for special picture or surround architectural solutions.

4.10. Poured into the mold or formwork solution was autoclaved aerated concrete monolith rising water resistant spontaneously begins to increase in volume and in 2-4 hours a porous mass of the solution is increased by about two times, given this solution to a form or formwork to pour a little more than ½ height.

4.11. Preparation of the solution of non-autoclaved aerated concrete monolith rising water resistant, pouring it into molds or into the mold in the factory and the construction site must be carried out at a positive temperature ambient conditions. In the absence of these conditions all of the above processing cycle operation should be performed or may be performed in an appropriate "warming up" with the devices mounted thereon for heating air.

4.12. Manufacturing of hardening solution and autoclaved aerated concrete monolithic waterproof increasing temperature up to - 20 ° C., but using in the production of hot water and then filled shelter surface film constituting the greenhouse effect.

4.13. At the construction site after pouring the solution autoclaved cellular concrete monolith prepared by growing water-resistant base, through the night to produce a work of leveling screed of cement sand mortar or equalize the tie of autoclaved aerated concrete monolith rising water resistant with the rules, "helicopter", etc.

The necessary condition for the maturation of the solution autoclaved cellular concrete monolith rising water resistant compliance thermohygrometric condition according to the technology maturation concrete GOST for seven days. This prevents non-autoclaved aerated concrete monolith rising water resistant from excessive evaporation of water, will create the best mode of education reinforced cellular concrete layer will be increased physical and mechanical properties of concrete, prevent the occurrence of cracks.

In the factory, the manufacture of piece goods, after stripping, products must be stacked on pallets and covered with plastic wrap for curing for 28 days. Sunlight on products are not allowed.

5. QUALITY CONTROL.

5.1. Incoming inspection of cement quality is determined by the actual activity of Standard 310.4 from each new batch.

5.3. Udoboukladyvemost solution aerated autoclaved concrete monolith rising water resistant device is determined Suttarda at least 1 time per shift at the time of filling mass in the form or in the formwork.

5.4. The strength of autoclaved aerated concrete monolith rising water resistant to compression according to GOST 10180-cubes on samples of size 10 * 10 * 10 cm or sample-size cylinders D = H = 10cm. Sampling at least two GOST 10180 every shift performed to determine grade strength after 28 days storage under normal conditions (+ 20 ± 5 ° C, humidity 95%).

5.5. The density of autoclaved aerated concrete monolith rising water resistant determined according to GOST 12730.1 on the samples used to determine its strength.
