Study on strength, durable and flexural behaviour of partial replacement of sugarcane bagasse ash over cement

Abstract

Tonnes of cement are produced and used due to boom in infrastructure sector. During the process of production of cement, lot of CO _2 has been emitted. It is estimated around 4%–8% of CO _2 has been emitted from cement production. There is high need for address this issue. Because of its renewable nature and high silica content, Agriculture waste ash is gaining popularity as a viable alternative to traditional cementitious materials. It has been found by (Hernandez et al 1998 ) that Sugarcane bagasse ash shows good pozzolanic activity. Sugarcane bagasse ash (SCBA) is a waste-free renewable energy source made from sugarcane fibres. Many attempts have been made to study the SCBA as partial replacement for cement. The same has been checked in this study with extension for structural members have been done. The results of tests on concrete and concrete containing a partial replacement of cement made from sugarcane bagasse ash (SCBA) are the most important details in this text. The substitution of 10% SCBA resulted in the greatest increase in compressive strength, followed by a modest increase in split tensile strength maximum strength. The study findings allow for the conclusion that the Concrete that was built has high durability qualities. The flexural behaviour also showed very good performance. The use of Bagasse Ash shows improved performance due to is micro grain size and crystallographic nature. The replacement of 10% SCBA results in overall better performance.
