FLUOROSILICATE-BASED ADDITIVE COMPOSITION FOR A CONCRETE WITH READY-MIXED CONCRETE PROPORTION

摘要

PURPOSE: Provided is a fluorosilicate-based additive composition for a ready mixed concrete-forming mortar, which can improve initial flow property, strength and water-proof property simultaneously. CONSTITUTION: The fluorosilicate based additive composition for a ready mixed concrete-forming mortar is characterized by comprising: 10 to 50 wt% of zinc hexafluorosilicate(ZnSiF6), 5 to 30 wt% of magnesium hexafluorosilicate(MgSiF6), 15 to 40 wt% of ammonium hexafluorosilicate((NH4)2SiF6), 1 to 5 wt% of sodium hexafluorosilicate(Na2SiF6), and 0.5 to 3 wt% of calcium hexafluorosilicate(CaSiF6).
