THIXOTROPIC FLOW AID-RUFA

THIXOTROPIC FLOW AID-RUFA

DESCRIPTION

RUFA (Reactive Ultra-Fine Fly Ash) is a new pozzolanic amorphous polymorphs additive, can improve the rheology, enhance the mechanical properties and increase the durability of cementitious material. RUFA is an inorganic silica aluminum compound. Its average particle size is 1/10 of cement particle and 10 times of silica fume particle, very good performance in pumping, thixotropic rheology and shrinkage compensation.
