EXAMPLES OF THE MULTICRITERIA OPTIMIZATION OF CEMENT-BASED COMPOSITES

The materials considered in the paper are called concrete-like composites or materials with cement-based matrices. These are not only ordinary and high performance concretes, but also materials with different admixtures, dispersed fibre reinforcement, polymers, etc. The selection of the most appropriate material composition and internal structure is proposed using the methods of the optimal design. In the paper basic methods of mathematical optimization are briefly discussed and applied to the formulation and solution of six different problems. The main aim of the paper is to demonstrate how the optimization approach may be used in practical situations of the design of high performance concretes.
