Description
Formiat of sodium (sodium muravyinokisly) — chemical compound with a formula HCOONa, a by-product of a proizvodstvapentaeritrit. It is used as a reducer in organic synthesis. Formiat of sodium represents technical formiat sodium with insignificant impurity of pentaerythritol and its derivatives. Formiat of sodium technical is used as the antifrosty and plasticizing additive in production of building constructions, in the tanning industry as the agent in pretannic operations as raw materials in production of formic acid. As antifrosty additive formiat sodium is applied at construction of monolithic concrete and reinforced concrete designs, monolithic parts of combined and monolithic designs and a zamonolichivaniye of joints of combined designs, and also at production of combined concrete and concrete goods on grounds at the established average daily temperature of external air it is lower than 5 degrees. Concrete with this additive is forbidden to be applied in previously strained designs reinforced by steel of the classes AT-IY, AT-YI, A-IY and A-U, in the concrete and reinforced concrete designs intended for operation in water and gas environments at relative humidity of air more than 60% in the presence in filler of inclusions of a reactive kremnez in reinforced concrete designs to the electrified transport and the industrial enterprises applying direct electric current. Formiat of sodium is entered into concrete mix in quantity: — 2% of the mass of cement in terms of a dry formiat of sodium at a settlement temperature of curing to −5 °C; — 3% of the mass of cement in terms of a dry formiat of sodium at a settlement temperature of curing to −10 °C; — 4% of the mass of cement at recalculation on a dry formiat of sodium at a settlement temperature of curing to −15 °C. At preparation of concrete (solution) additive needs to be dissolved in warm water. The received solution is added together with zatvoreniye water. The received solution should be dosed in a betonosmesitel via the batcher of chemical additives or via the water batcher, at the same time it is necessary to cut a zatvoreniye water consumption on 7-13%
