MULTIFUNCTIONAL BINDER COMPOSITION USING PAPER ASH

摘要

PURPOSE: A multi-functional binder composition is provided to replace cement with paper ash, prevent contraction crack and enhance strength of cement. CONSTITUTION: A multi-functional binder composition using paper ash contains: 20-80 weight% of mixture of paper ash and calcium sulfateα-hemihydrate; 0.01-20 weight% of neutral activation reagent or mixture of neutral activation reagent and alkaline activation reagent which induces Geopolymer reaction to form polycyalate polymer(Si-O-Al-O); 10-70 weight% of sand; and remaining amount of additive.
