摘要

This paper discusses the characterization of sugar industry solid waste as pozzolanic matehals. Research on the reaction kinetics between calcium hydroxide (CH) and sugar cane straw ash and bagasse ash with 20% and 30% clay, calcined at 800℃ and 1000℃, is described. A simple experimental technique was utilized based on the electrical conductivity measurement of a CH/waste suspension correlated with concentration. A mathematical model, which was elaborated by the authors in previous work, was utilized to describe the reaction kinetic process. The kinetic parameters (diffusion coefficient and reaction rate constant) of the model were determined with relative accuracy in the fitting process of the model. This procedure allowed an economical and rigorous evaluation of the pozzolanic activity of sugar cane straw ash and bagasse ash and ensures their efficient use in the cement industry and in the production of low cost binders.
