This research examined the impact of cement replacements with Grade 100 ground granulated blast
furnace slag (GGBFS) on portland cement concrete performance. GGBFS was used to replace 0%, 30% and
50% of cement in a series of mixes with w/cm = 0.45 where primary variables were coarse aggregate type,
cement manufacturer, and curing regime. The primary performance measures were compressive strength
development and deicer freeze-thaw scaling resistance. The results show that the amount of time needed to
reach 3000 psi traffic opening strength more than doubled from 3 days to 7 days with 30% GGBFS and to 10
days with 50% GGBFS. GGBFS concrete strength becomes comparable to ordinary portland cement concrete
after 56 days. Deicer freeze-thaw scaling tended to increase with increasing GGBFS levels and appeared to be
tied to the level of carbonation at the surface. Traditional curing methods were less effective with GGBFS
concrete in providing a durable surface. In summary, under certain conditions Grade 100 GGBFS can be used
successfully in Wisconsin pavements. The seemingly minor variations that result from different mix constituents
in OPC appear to be accentuated in GGBFS concrete. A 50% GGBFS cement replacement level usually results
in unsatisfactory performance from primarily a scaling perspective. A 30% GGBFS cement replacement level
will often be acceptable but the outcome depends on the specific constituents and curing methods used. |
