As the foam to produce foam protein pinokontsentrat foam dice recommended as the optimal foam dice

Classical foam dice technology manufacturing concrete is a mixture of pre-prepared foam soluble mixture. Foam concentrate and water for preparation of foam dosing in volume. Ready mixed solution to obtain foam to foam. Foam blowing agent enters to produce foam. In mixer loaded water, cement and sand - mass and prepare soluble mixture. Then the mixer is supplied with foam Foam and stirred for 3 5 minutes. Further foam made in mixers, transported by a flexible hose, to the place of installation, foam dice whether foam dice in the form formwork. Estimated consumption of components in the production of concrete
Estimated consumption of components 1 m concrete * pinokontsentrata consumption depends foam dice on the brand, and less than 2 kg. 1 m density foam cement concrete M-500 kg sand kg 300 kg / m 270 0.0 400 kg / m 360 0.0 500 kg / m 430 0.0 600 kg / m 382 160 700 kg / m 426 210 800 kg / m 470 260 900 kg / m 520 300 1000 kg / m 565 350 components necessary to produce foam concrete mix cement
And gravel as heavy filler are required. foam dice Perhaps foam dice the addition of lightweight aggregate such as expanded foam dice clay), while the strength of porous concrete with the same bulk density can increase foam dice by 100 - 200%. Small aggregates
Generally, for the preparation of concrete mixture foam dice density up to 400-600 kg / m (for roof and floor insulation coating) sand is used. Since foam density of 600 kg / m as fine aggregate used natural or crushed sand. Preferable to use river sand. It should be clean, with no inclusions. To conclude fines apply sand 0-0,2 mm. Clay particles should foam dice not exceed 2-3%. Water
In the manufacture of foam is recommended to use drinking water without any verification. The content of water in porous concrete foam dice consists of the estimated number needed to zatvorenija solution and water contained in the foam. Before adding foam cement foam dice ratio solution should be at least 0.38. Too low value of the water-cement ratio can cause the product to obtain foam dice a higher than specified, the bulk density. This is because the concrete foam dice will take the foam need for chemical and physical interactions water, causing partial destruction of foam, ie reducing its volume in gas concrete mixture. The optimal ratio - in the range of 0.4 to 0.45. The water temperature is not allowed above 25 C. Pinokontsentrat
As the foam to produce foam protein pinokontsentrat foam dice recommended as the optimal foam dice price / quality. In the present document describes how five basic cooking foam (concentrate), foam dice including and protein. Consider, for example, one of them - kleyekanifolnyy pinokontsentrat: factor out then K = 500 (1 kg pinokontsentrata - 500 liters of foam); homogeneous pore foam, very small, foam dice closed structure (diam. then 0,1 - 0,4 mm); Average density foam - 90 g / L foam stability (50% water branch) foam dice in concrete mix - at least 10-14 hours
To make kleyekanifolnoho pinokontsentratu, the following materials: pine rosin GOST-1911-84 150 m; Glue bone GOST-2067 100 m; Sodium hydroxide GOST-4328-77 20 g
Pinokontsentrat should be stored in sealed plastic or wooden barrels, sheltered from direct sunlight, at temperatures foam dice above + 30 C. Pinokontsentrat withstand lowering the temperature to 5 C. Term conservation since cooking is 15-30 days Preparation of foam concrete mixtures
We recommend the following sequence of mixture preparation: first poured sand (prior to bind water mixture), then cement is added and everything is mixed until a homogeneous color mixture. It is important to optimally distribute cement in the sand. Then a mixture of dissolved water in an amount corresponding to the selected recipe. Stirring was continued until a homogeneous plastic mass
Then use penoheneratora defined portion of the foam (according to the required density foam) is fed through the hose to the mixer, where for about 120 - 180 seconds before it is mixed with cooked cement-sand mixture. By controlling the density that is given, we can easily obtain the required strength of concrete in compression. Hardening of concrete and overseeing the
Cast porous concrete, like any other, zv'yazanomomu cement, create temperature-humidity regime. It is, on the one hand, to support the hydration of cement,
