Potential of cement-treated sugar cane bagasse ash (SCBA) as highway construction material

Sugar cane is a particularly useful product in developing countries and its production rate is impressive in countries including Cuba, Brazil, India, Thailand, Pakistan, Colombia, Mexico and The Philippines. Unfortunately, as is the case with almost every useful material, it leaves behind its waste as ash, which is largely dumped in landfills. These landfills destroy the appearance of the landscape as well as rapidly becoming an environmental burden. Use of bagasse ash in soils and in concrete has been successfully proven, but its possible potential as a highway construction material remains to be demonstrated. This paper aims to explore it as a useful material for highway construction. To test its potential as a subgrade material, compaction tests, and unconfined compressive strength and California bearing ratio (CBR) tests were conducted for evaluation. Sugarcane bagasse ash (SCBA) was mixed with cement content in proportions of 3%, 6% and 9% and then properly cured. The results were strikingly positive. The highest maximum dry density obtained was 727.8 kg/m3 for the 9% cement–SCBA mix, with a compressive strength value of 6.46 tonnes/m2. Highest CBR values were 7.3% for the 4-day cured sample and 23% for 40-day cured sample. Recycling of SCBA waste in productive construction activities will yield profoundly positive results in terms of environmental protection, waste management practices, and saving of raw materials.
