NARDI, José Vidal and HOTZA, Dachamir. Determination of composition of pozzolanic waste mixtures with optimized compressive strength. Mat. Res. [online]. 2004, vol.7, n.2, pp. 373-375. ISSN 1980-5373. http://dx.doi.org/10.1590/S1516-14392004000200027.
The utilization of ceramic wastes with pozzolanic properties along with other compounds for obtaining new materials with cementating properties is an alternative for reducing the environmental pollution. The acceptance of these new products in the market demands minimal changes in mechanical properties according to its utilization. For a variable range of compositional intervals, attempts were made to establish limiting incorporation proportions that assure the achievement of minimum pre-established mechanical strength values in the final product. In this case minimum compressive strength value is 3,000 kPa. A simultaneous association of other properties is also possible.
