Abstract

Cement is one of the most used building materials in the world. The production of ordinary Portland cement contributes to the release of harmful greenhouse gasses. In an effort to reduce these emissions, different materials are being evaluated for their use as partial replacements for ordinary Portland cement. Rice husk and sugarcane bagasse are agricultural waste products and large amounts of these are currently landfilled, making them inexpensive and available. When combusted at high temperatures they form rice husk ash and sugarcane bagasse ash that have pozzolanic characteristics. The high silicon dioxide in these products makes them good options to use as partial replacement for OPC. This study evaluates compressive strength, porosity and corrosion resistance of hardened cement paste containing rice husk ash and sugarcane bagasse ash as partial replacements for ordinary Portland cement.
