STUDY ON STRENGTH CHARACTERISTICS OF CONCRETE BY PARTIAL REPLACEMENT OF CEMENT WITH ALCCOFINE

Abstract

The growth in the next leg of industrialisation and urbanization infrastructure is the biggest catalyst of India’s growth. A landmark in history has been created by manufacturing Alccofine which is a new generation ultrafine low calcium silicate product. It is a typical ground granulated blast slag furnace modulated by certain chemicals. It is specially processed material based on slag of high glass content with high reactivity obtained through the process of controlled granulation. It consumes calcium hydroxide from the hydration of cement to form additional C-S-H gel. The partial replacement of cement with Alccofine reduces water demand for same workability. It produces dense pore structure and ultimately higher strength gain. For growing infrastructure especially at low levels of high buildings, high strength concrete is required. This partial replacement results in better durability also. In the present study, the strength characteristics of concrete are observed by partially replacing the cement in concrete with 8%, 10% and 12% Alccofine and compared with normal concrete.
