The Use Of Mathematical Modelling In The Composition Of A Composite Material

The practice of cement production uses a wide range of industrial subproducts; indeed, the inclusion of these industrial waste products can improve some of the properties of cement. This article reports on a study of the quantitative influence of formulation parameters (including additives) on the mechanical properties of a cement-based composite material (CM) in the course of one-year hardening. A three-parameter polynomial model is used for the determination of the amount of the composite components cement, active additive and granulated blast-furnace slag. The authors show that by using this approach, the component's influence on the changes of compressive strength of the composite can be evaluated. By using the model, it is possible to determine the optimal quantity of the new active additive, depending on the composition of the other two components. The authors conclude that their results confirm the positive effect of the preliminary mechanical-chemical activation of the acidic granulated slag and the used new active additive on the strength properties of the silicate composite.
