Assessment of M30 Grade Self Compaction Concrete by Partial Replacement of Bagasse Ash in Place of Cement and Glass Powder in Place of Fine Aggregate

Abstract

Abstract: Self-compacting concrete (SCC), a recent innovation in concrete technology, has numerous advantages over conventional concrete. Self-compacting concrete, as the name indicates, is a type of concrete that does not require external or internal compaction, because it becomes leveled and consolidated under its self weight. SCC can spread and fill all corners of the formwork, purely by means of its self- weight, thus eliminating the need of vibration or any type of consolidating effort. This report demonstrates the possibilities of using Bagasse ash and Glass powder as partial replacement of cement and fine aggregate in concrete. This experimental investigation was performed to evaluate the strength properties of concrete, in which the cement is partially replaced by Bagasse ash and fine aggregate was partial replaced with Glass powder. Cement was replaced by weight with five percentages (0%, 5%, 10%, 15%, 20%) and fine aggregate was replaced with only one percentage (20%) of Glass powder by weight. Fresh properties of self-compacting concrete were studied. Compression test, splitting tensile strength and flexural strength test were carried out to evaluate the strength properties of concrete at the age of 7, 14, and 28 days.
