RECYCLING OF BAGASSE ASH IN THE RAW MIX DESIGNING AND CUNKERIZATION OF HIGH STRENGTH PORTLAND CEMENT AS A RAW MATERIAL AND ITS IMPACT ON CLINKER POTENTIAL AND FUEL CONSUMPTION

摘要

Bagasse ash from sugar mills of the North West Frontier Province (NWFP) has been used in the raw mix designing for high strength Portland cement and subjected to clinkerization. The clinker was converted into cement, and different parameters of the resulting clinker and cement were studied and compared with the British and Pakistan standard specification. It has been found that bagasse ash can be utilized in the raw mix up to 5% only, above which the chemical and physical parameters of the resulting clinker and cement are disturbed. With addition of 5% Bagasse ash, 6.46% energy is saved, while emission of carbon dioxide to the environment is decreased up to 1.73%. The use of 5% Bagasse ash replaces clay up to around 5%.
