ALUMINOSILICATE ACID-RESISTANT BINDING AGENT, AND METHOD FOR ITS OBTAINING |
摘要 |
FIELD: construction.SUBSTANCE: method for obtaining an aluminosilicate acid-resistant binding agent, which involves wet grinding of stone screening dust to specific surface of 1500-7300 m/kg so that a suspension with humidity of 14-22% is obtained and with content of particles of less than 5 mcm 30-50%, its mixing with sodium silicofluoride during 5 minutes with further mixing with liquid glass with silicate modulus of 2.6-3.0 during 3 minutes at the following component ratio, wt %: the above liquid glass 25-30, the above suspension (on dry basis) 62-71, sodium silicofluoride 4-8. The aluminosilicate acid-resistant binding agent is characterised by the fact that it is obtained by the above method.EFFECT: increased acid resistance of a binding agent at simultaneous simplification of its production process.2 cl, 1 ex, 2 dwg, 3 tbl |
