Abstract:This work describes the characterization of sugar cane bagasse ashes produced by controlled burning and ultrafine grinding. Initially, the optimum burning conditions of the bagasse were determined aiming the maximum pozzolanic activity. In sequence, an ultrafine sugar cane bagasse ash was produced in vibratory mill. Finally, the influence of use of ultrafine sugarcane bagasse ash (10, 15 and 20% of cement replacement, in mass) in properties of high-performance concretes was studied. Rheology (BTRHEOM rheometer), compressive strength (7, 28, 90, and 180 days) and rapid chloride penetrability were investigated. The results indicated that the addition of sugarcane bagasse ash improved the durability characteristics, and did not change the rheological and mechanical properties.
