Abstract High performance concrete (HPC) is produced in this study by utilizing the agriculture industry by-product. The usage of byproduct helps to condense the disposal issues, ecological degradation and also makes the production of concrete economical. The raw sugarcane bagasse ash from sugarcane industry is processed to ensure the suitability with the properties of cement to be used in HPC. Sugarcane bagasse ash (SCBA) is used as binder in HPC as an alternative of ordinary Portland cement. The properties of the SCBA have been studied. Investigation were carried out experimentally on M 60 grade of high performance concrete blended with SCBA to assess the workability, strength and durability properties at different ages of curing. Three SCBA blended HPC specimens were tested for each trial and test. Test results indicate improved performance in strength and durability properties up to 15% substitution level of SCBA with ordinary Portland cement. Keywords Sugarcane bagasse ash . High performance concrete . Workability . Strength . Durability
1 Introduction The partial substitution of cement with pozzolanic materials in concrete provides the positive idea to solve environmental issues and durability loss in structures. Studies have revealed that chemical composition of pozzolanic materials have considerable quantity of silica. During hydration process, the amorphous silica in pozzolanic material reacts with lime and forms a new product (silicate hydrate), thus improving the properties of concrete [1]. Bagasse is a primary by-product of the sugarcane industry. It is the fibrous residue of sugarcane, after the sugar cane is crushed and the juice is extracted. In India sugarcane production was about three thousand million tons per year and plenty of bagasse is available in sugar industry [2]. As a fuel, bagasse is partly used in sugar industry and the remaining was dumped as waste material in ground. The usage of bagasse ash as pozzolanic material in concrete or mortar combinations as partial substitution of cement results in optimistic approach to environmental issues, because it minimizes the issues related with to disposal.

suggested the method of confining the sugarcane bagasse ash with suitable process, which influences the chemical and mineralogical composition. The reaction between lime and bagasse ash to monitor the pozzolanic properties depends on lime content, pore structure, reaction products [4]. The results showed that unburnt bagasse ash does not act as pozzolanic material, but sugarcane straw ash showed better pozzolanic action than rice husk ash. The presence of 10% bagasse ash improves the compressive strength va
