Study on Microstructural Characterization of Concrete by Partial Replacement of Cement with Glass Powder and Rice Husk Ash in Concrete

Abstract

Sustainable development is the only logical response to the never-ending demand in any sector of expansion and industrial progress. Housing is another inescapable habit that must be controlled and aligned in order to achieve long-term sustainability. The usage of cement is required for this process. The cementitious content producing units contribute more to global carbon-di-oxide emissions than the aviation sector. This industry contributes for around 7% of total carbon-di-oxide emissions. The six key issues identified by society are climate conservation, fuel and raw materials, employee health and safety, pollution mitigation, local impacts and internal company operations. As a result, alternative materials and technology that could solve the problem aid in the preservation of natural resources while simultaneously acting as a pollution-mitigation tool.According to Ubong [1], the need to develop alternative materials to current traditional ones, as well as to intensify sand Crete blocks, has motivated researchers to concentrate their efforts on cement substitutes in sand Crete blocks. This research investigates into the use of coconut husk ash (CHA) in sand Crete blocks. The coconut husk ash was used in 5 percent increments up to 30 percent. The compressive intensity of cement/coconut husk ash sand Crete blocks diminishes as the percentage of coconut husk ash content increases. According to Krishna [2], the use of durabilityenhancing supplemental cementing solutions has become extremely important to the long-term service survival of concrete frameworks. Bakar [3] investigated the impact of foundry sand and bottom ash in equal amounts as a partial replacement for fine aggregates in varying contents (0-60%) on concrete assets.
