Abstract

Mechanical properties of mortars and concretes blended with GCC(Ground Calcium Carbonate slurry) and silica fume were investigated. Results from this study showed that air contents of mortars were constant regardless of replacement of GCC and flow values of mortars were decreased with replacement of it. Especially, mortars and concretes replaced with 10% of GCC had a good trend with respect to compressive strength. In case of simultaneous use of GCC and silica fume, the workability and compressive strength of the concretes seem not to be any problems in mechanical properties. This study indicated that the most reasonable replacement of GCC was 10% and the addition as fine aggregate was more effective than that as binder.
