Sand-sodium-silicate mixtures steam-microwave structuring technological peculiarities

Steam-microwave structured sand-sodium-silicate mixtures highest technological properties have been obtained under conditions if they are initially in free-flowing state, used sand is mainly fractions of 0, 16 ... 0, 20 mm and, after cladding with sodium silicate solute, sieved through sieve with 0.315 mm mesh. For structuring, water steam should be fed into mixture as water charges. Their location in rigging allows the water steam, released from them, to move in direction from rigging dead-end parts to mixture open surface. Water mass single water charge is 1 ... 3 g of water per 2, 5 kg of mixture. When structuring, do not allow interruption of microwave radiation influence on mixture for more than 20 ... 30 seconds before it ends.
