reactive powder concrete full report
Presented By:

abstract
RPC is able to obtain its improved properties by using a very dense mix, consisting of fine particles and fibers.
Low w/cm ratio : 0.16 to 0.24 (as low as 0.13)
Type 20M (like type II) Portland cement (no C3A less HoH)
Silica fume (25% by weight)
Water
High dosages of superplasticizer
Fine quartz sand (150-600μm) (SG=2.75)
Steel fibers (2.5-10% by volume) for toughening
No rebar needed!
Cured in steam bath for 48 hrs @ 190ºF (88ºC) after initial set, placed under pressure at the molding stage
