Abstract - Conventional concrete is responsible for amount
pozzolanic materials. Pozzolanic material contains high amount of silica, addition of these materials helps silica (SiO2) to react with free lime released during heat of hydration which reduces carbon-dioxide emission. Industrial waste such as fly ash, blast furnace slag, silica fume contains pozzolanic properties, in addition agricultural wastes also contains high amount of pozzolanic properties in rice husk ash, wheat straw ash and sugarcane bagasse ash. Sugarcane is a major crop grown in about 115 countries which has production 1600 million tonnes yearly. India produces 300 million tonnes of sugarcane per year. A thousand tonne sugar cane produce 26% of bagasse and 0.62% of bagasse ash. This ash is produced by controlled burning of sugarcane bagasse above 120oC and below 800oC. After burning bagasse it gives amorphous silica which has pozzolanic properties. Bagasse ash contains around 68.82% of silica which helps to reduce carbon emission after reacting with cement and it also contains sugar in some amount which is responsible for increase in strength. Therefore it is possible to use Sugarcane Bagasse Ash (SBA) as partial cement replacement material to improve quality, strength and reduce cost of construction.
of carbon-dioxide emission to some extent. So to reduce the emission, various types of concrete are developed using waste products from industries and agricultural use like blast furnace slag, rice husk, fly ash which requires low amount of energy and also cause least harm to the environment. Bagasse Ash generated in Sugar industries after burning bagasse it creates disposal problems, when bagasse ash is disposed in open environment it causes various health problems which has led to urgent ways to handle bagasse ash. As Bagasse ash possess pozzolanic property as that of cement it was partially replaced with cement for 10%,20%,30%, and 40% for M30 grade of concrete and also examined for concrete properties like workability, compressive strength, split tensile and Flexural strength. After obtaining results for above tests 10% replacement proved optimum replacement. Key Words: Fly Ash, SBA, Carbon Dioxide, Split Tensile, Sugar Factory.
1. INTRODUCTION
Development of world is mainly based on the infrastructure of various nations in large scale. Increase in infrastructure leads to use of various material during construction which also have disadvantage in some extent. Ordinary Portland cement (OPC) is recognized as one of main construction material used worldwide. In today’s world, global warming is increasing due to rate of carbon-dioxide (CO2) emission through various materials, in which cement is also one component which emits 5-8% CO2. When cement and water are considered individually they do not contain individual strength nor they can act as binder, but when they are mix together for a purpose at that time calcium oxide (CaO) and silica oxide (SiO2) react with water to form Calcium Silica Hydroxide gel (C-S-H) which brings strength to the mixture. As it is exothermic reaction, heat is generated which is known as heat of hydration. When this reaction exists the emission of carbon-dioxide takes place which contributes in GHG phenomenon. When the studies was carried out it was identified that partial replacement of cement can be done using various

1.1 MATERIALS & METHODS: CEMENT: Cementitious material used was OPC 53 grade, Is the main ingredient used in for bonding of concrete. The usage of other cement is possible but depends on local availability. Supplementary cementitious material is replaced with bagasse ash at about 10% 20% 30% 40% with cement. The test conducted on cement are initial setting time, final setting time, soundness, specific gravity test.
FINE AGGREGATE: Fine aggregates used were available
on site and are tested, the results are as per Indian standards BIS: 383: 1970. Specific gravity of fine aggregate is 2.94. These are used in replacement to river sand. Use of fine aggregate improves the compressive strength of concrete. The aggregates to cement ratio usually varies between 4:1 to
