Broadview Technologies’ “Hycrete” concrete additive was used for the first time by the Kansas DOT in constructing a bridge. The pour used over 450 cubic yards of concrete with Hycrete being used at a dosage of 2 gallons per cubic yard. As a result of the superior anti-corrosion properties and lower moisture permeability imparted by Hycrete, a combination of mild steel and epoxy coated re-bar was used.
Hycrete was chosen as a result of extensive research by the Kansas DOT as well as multi-year studies conducted by the University of Connecticut and the University of Massachusetts. The research indicated that Hycrete’s ability to retard corrosion of rebar and to lower the moisture permeability of concrete would increase both the structural and cosmetic life of the concrete. Life 365 algorithms predict a 4-10 times increase in the useful life of the bridge.
All present for this pour were extremely impressed with what they described as the “better workability” of the concrete with Hycrete. Hycrete was chosen over silica fume and calcium nitrite combinations. For more information, call (973) 465-0077.
