Multicriteria optimisation of the formulation of modified fine-grained fibre concretes containing carbon nanostructures

The experimental studies allowed optimising the formulations of modified fine-grained fibre concretes, which makes it possible to determine the rational compositions of cement composites based on the main strength properties (the compressive strength and tensile strength in bending). The volumes of the allowable range and frequencies of distribution of intervals of the strength values under study characterising the stability of the applied technology were determined. The results of multicriteria optimisation allowed identifying the zones of intersection of tolerance ranges of the compressive strength and tension in bending, which characterise the preferable regions of the factors and strength characteristics investigated.
