| you are: Inorganic knitting substances
On a chemical compound they share on four groups: экстракте тоути цены
1) limy knitting, consisting mainly from okisi calcium of SaO;
2) magnezialnoe knitting, containing kaustichesky magnesite MgO;
3) plaster knitting which basis is sernokislyj calcium;
4) liquid glass - silicate of sodium or kalija (in the form of a water solution).
The Hydraulic knitting harden also long time keep durability (or even raise it) not only on air, but also in water. On the chemical compound hydraulic knitting substances represent the difficult system consisting in basic from the connections of four oxides. These connections form three basic groups of the hydraulic knitting:
1) the silicate cements consisting mainly (on 75%) from calcium silicates; them concerns portlandtsement and its versions - the main things knitting modern building;
2) aljuminatnye the cements, a knitting which basis are calcium aluminates; the main thing from them is glinozemistyj cement and its versions;
3) hydraulic izvest and the novel-cement.
Knitting avtoklavnogo tverdenija are the substances capable at avtoklavnom synthesis, occurring in the environment of sated water steam, to harden with formation of a strong cement stone. into this group enter: izvestkovo-kremnezemistye, izvestkovo-cindery, izvestkovo-slag knitting, nefelinovyj cement, etc.
