Development of Local Bagasse Ash as Pozzolanic Material for Use in Concrete

Burhan Sharif, Rafia Firdous, Muhammad Akram Tahir

Abstract


Concrete is one of the extensively used materials in construction industry. General construction uses ordinary Portland cement, however for specialized projects specific properties of concrete are tailored using different pozzolans. Sugarcane bagasse ash is abundantly available in Pakistan as being obtained from sugar mills which uses sugarcane bagasse as fuel. This research is focused to determine the maximum pozzolanic activity of sugarcane bagasse ash. Raw bagasse ash was calcined at temperatures of 500, 600 and 700 degree Celsius for 1, 2 and 3 hours heating duration. ASTM C 618 and C 311 were used to determine the suitability of sugarcane bagasse ash for its pozzolanic activity. It was found that maximum pozzolanic activity is achieved at a temperature of 500 degree Celsius for 1 hour heating duration and same was verified by X-ray diffraction analysis of calcined sugarcane bagasse ash
