CONCRETE PROPERTIES EVALUATED BY REPLACING CEMENT WITH ALCCOFINE

Abstract

Nowadays, many research works are being conducted throughout the world to develop cementitious materials that can replace cement. As a replacement for cement in concrete, fly ash, silica fume, GGBS, Metakaolin, Micro materials, Quartz powder, etc. are tried out in that order. This experiment tries out a new ultrafine material called Alccofine for a partial replacement. This concrete grade, M40, was developed for testing the cementing efficiency of Alccofine with a variety of percentages of replacement of cement with Alccofine, such as 5%, 10%, 15%, and 20%. A design mix has been developed for M40 grade and cubes have been cast with varying percentages of alccofine, as described above. A discussion of the results has been provided. Compared to other mix percentages, 15% of alccofine replacement with cement produces good strength. The SEM images show that Alccofine is found to have good cementing efficiency in earlier ages of concrete.
