ABSTRACT
A method for multi-parametric design of concrete compositions is proposed for a case when in addition to the strength properties and concrete mix workability, indicators of other properties are normalized. The calculation schemes features for solving concrete composition design problems, taking into account in addition to strength a number of other properties, are considered. It is shown that in these design schemes, dependences for concrete strength with other normalized properties, as well as multifactorial polynomial models specially obtained for given conditions, can be used. The latter allows more accurate prediction of the given concrete properties under specific conditions. When using a complex of mathematical models, the solution is found using mathematical programming. To illustrate the effectiveness of the proposed algorithms for multi-parameter design of concrete compositions, examples of solving problems aimed at finding concrete compositions for a given workability index, providing required shrinkage deformations, strain, modulus of elasticity, frost resistance and water impermeability are presented.
