Durability and Cementing Efficiency of Alccofine in Concretes

Abstract

In the modern era, many research works are being carried out throughout the world for finding out a suitable cementitious material for the replacement of cement. In this order fly ash, silica fume, GGBS, Metakaoline, Micro materials, Quartz powder, etc. are tried out for replacing partially or full of cement in concrete. A new ultrafine material called Alccofine is tried out for replacing partially in this thesis. M20 grade of concrete is intended to study the Durability And Cementing Efficiency of Alccofine in concretes by replacing the cement with Alccofine of various percentages such as 5%, 10%, 15%, 20%. Design mix is made for M20 grade and cubes were cast with various percentage of alccofine as said above. In this phase-II, all the durability studies are carried out as per as per Indian standards to determine the properties. The results are presented and discussed. It is observed that 15% of alccofine replacement with the cement is yielding good strength as compared to other mix percentages. Also it is determined that the cementing efficiency of alccofine is good in earlier ages of concrete.
