The invention relates to building materials and may be used in the manufacture of wall insulation, finishing products, cellular concrete, and other materials for civil and industrial construction.
Known for high performance concretes (EN 2323910, 04 28/04, publ. 10.05.2008; EN 2425814, C04B 28/04, publ. 10.08.2011; EN 2331602 04 28/04, publ. 20.08.2008), consisting of Portland cement, sand, gravel, water, comprising the Sol hydroxide iron (III with density 1,018-1,021 g/cm 3 without plasticizer, with «Peramin SMF-10 and the complex of (II) potassium (K 4 [Fe(s n) 6 ]) - 0,80-0,85 with -3.
Presence in the mixtures of these additives allows to increase the strength of cement concrete with compression, bending, impact and reduce the creep.
But these decisions apply only to products on the basis of Portland cement. If you are using another binder, for example, magnesia, introduction Zola ferric can lead to different results.
Closest to the claimed composition is based on binder (EN 2380334, 04 28/30, publ. 27.01.2010) containing 60 to 65% of a magnesia astringent, 15...17% of magnesium chloride, 3...10% additive of iron ore, the rest is water.
iron ore as supplements can increase the strength of magnesia stone to 76.2 MPa and above, reduce water absorption stone from 12% to 0.74...1,73%, reduce water absorption, raise water resistance.
The disadvantage of the nearest analogue is that the proposed addition you can use to grind her dosage significant and additive is scarce.
The invention solves the problem of lowering the hygroscopicity, increase strength and water resistance and ensure stone resistance to formation of cracks (uniformity volume changes over time).
This is achieved in that the composition contains magnesium? astringent, aqueous solution of magnesium chloride and Sol hydroxide iron (III with density 1,018-1,021 g/cm 3 and hydrogen index 4,5-5,5 with the following component ratio, mass. %:
magnesium? astringent
60,00...75%
magnesium chloride
14,4...17,0%
Sol Fe(Oh) 3
0,5...1,0%
water restFrom the amount used in the composition of the binder depends on the strength of the received stone, its density and other properties. Binder with the contents of active magnesium less than 60% will be ineffective, and with MgO content of more than 75% it is more expedient to use in production of refractories.
Introduction in the composition of magnesium chloride should be in strictly defined limits, as it affects the phase structure of magnesia stone and accordingly on all of its properties. At low costs of magnesium chloride structure of magnesia stone is formed from a mixture of and magnesium hydroxide, which reduces the uniformity, the strength of the stone and its resistance to environmental influences. Too high costs of magnesium chloride lead to excess, the emergence of efflorescence on the surface of products and a significant increase in the hygroscopicity of the received material.
Introduction Zola Fe(Oh) 3 in magnesia mix in the quantity of which is less than 0,5% by weight of binder, not effective, and more than 1% - is harmful, since the addition of newly causes an increase hygroscopicity, reducing water resistance and durability of the resulting stone.
Additive Zola hydroxide of iron in the composition of a magnesia astringent, contributes to the destruction of large crystals of burnout in the initial period of hardening and comprehensiveness of hydration binder, some changes in phase composition of tumors. Highly active Sol iron hydroxide, dimensions ions which are commensurate with the magnesium ions actively embedded in the structure of and magnesium hydroxide, changing the habit of crystals, condensing the structure of stone, changing its resistance, water absorption and water resistance.
Composition obtained as follows.
Sol iron hydroxide, in the form of specially prepared colloidal solution, in the amount of 0.5 to 1% by weight of binder injected into . After a preliminary mixing with the prepared aqueous solution of magnesium chloride density of 1.20, 1,22 or 1.24 g/cm 3 , the solution of averaged out and then injected as a comprehensive sealer in knitting. Mix carefully mix until smooth.
The resulting mixture is prepared samples- size 4*4*16 cm, which in natural conditions at a temperature of 20±5 C and a relative humidity of 70±5%.
Next studied the basic properties of the received magnesia stone, modified iron hydroxide. Determined compressive strength, moisture resistance, water resistance and soundness of.
The test results of samples are shown in table 1.
From obtained results follows, that at density sealer 1,22...1.24 g/cm 3 and the specified quantity of the entered additive strength of magnesia stone rises to 73 MPa and 20...35% higher than the strength of compositions.
Additive Zola raises water resistance of a stone from 0.6 to 0.8, reduces water absorption from 8% to 2% and simultaneously increases crack resistance of magnesia stone, which increases the durability of magnesia products.
Introduction Zola hydroxide iron (III as nano-additives in magnesia composition instead of iron ore saves raw material resources, metallurgy, and improve the quality and effectiveness of the received material.
