Effect of Alccofine Addition on the Compressive Strength of High-Strength Concrete Cubes
Main Article Content
Abstract
Researchers, scientists, and industrialists are involved in numerous research activities worldwide to find suitable replacement materials for cement due to the environmental pollution caused by CO2 emissions during cement manufacturing. Various materials such as fly ash, silica fume, GGBS, metakaolin, nano silica, and quartz powder have been explored for partial or full replacement in cement concrete. This thesis investigates a new ultrafine material called Alccofine (AF), which is manufactured from glass waste and iron slag from steel industries, as a partial replacement for cement. The study focuses on M60 grade concrete to evaluate the performance of high-strength concrete by replacing cement with Alccofine in various proportions: 5%, 10%, 15%, and 20%. The design mix proportion for M60 grade concrete is achieved as per IS 10262. Several specimens are planned to determine the mechanical properties, such as compressive strength, flexural strength, and elastic modulus of concrete. These specimens are cast and tested according to Indian standards. The results are analyzed and presented in the form of charts and graphs. It is observed that early-age strength is achieved for all combinations, with the 10% Alccofine replacement yielding higher strength than the other dosages.
