Abstract

Abstract In this paper we have made prognosis of flexural strengths of portland-cement after 3 and 28 days and pointed out importance of application of determined mathematical methods, which can be used for forming of mathematical models. Using of D-optimal plans and plans including “pseudocomponents”, original mathematical models are realized, which make possible, for different composition of four-component C-S-A-F system, to determine strength values of portland-cement after 3 and 28 days. For forming of corresponding mathematical models, for realization of qualitative prognosis, a polynomial of fourth order was used. Calculation of polynomial coefficients and determination of analytically form are made on calculator PDP 11/40.
