Experimental Study on Using the Ground Calcium Carbonate As a Concrete Admixture
Recently, the research results have been announced for the purpose of making high quality, according to the trend of a high performance of concrete structure. In this respect, we began to research the use of Ground Calcium slurry Carbonate (GCC) to a concrete admixtures which crushed the limestone until about 1.5 μm. We examined about the quality of GCC to fine out whether or not it would be feasible to use as the concrete admixture. The mechanical properties of concrete blended with GCC and silica fume were investigated. This study showed that air contents of concretes were constant regardless of replacement of GCC and the slump value of fresh concrete was decreased with replacement of it. Especially, concrete replacement 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 seemed to be favorable in mechanical properties. This study indicated that the most reasonable replacement amount of GCC was 10% of cement weight as concrete admixture.
