Extreme Simulation of Optimal Composition and Content of Micro-Filler in Concrete

On the basis of the environment of engineering and scientific computations Scilab, the programs of extreme simulation of experimental data Extr.sce and Interp.sce have been developed. The program Extr.sce makes it possible to optimize the initial compositions of micro-fillers with the use of data of the central composite orthogonal design of the full factorial experiment. On the basis of results of experimental data on determining physical-mechanical characteristics of fine concrete modified with micro-fillers of an optimal composition, the program Interp.sce makes it possible to define the optimal content of fillers in the composition of fine concrete. The solution of optimization problems is performed with the help of the search algorithm of maximal elements Max_z of interpolation data massive with obtaining their coordinates corresponding to the content of primary components of the micro-filler max_x and max_y, and plotting of visual models of data processing in the form of contour plots and 3d-plots of the interpolation surface for the program Extr.sce, as well as the search for maximal elements Max_y with obtaining coordinates corresponding to the content of the micro-filler in the composition of МЗБ max_x, with plotting of interpolation surface plots for the program Interp.sce. As a result of the use of the micro-filler content of which is optimized with the help of the developed program Extr.scr, on the basis of the extreme simulation in the program Interp.sce, it is possible to obtain the fine concrete with flexural strength 10,5 MPa at the filler content 10.3% of cement mass, compressive strength 47.37 MPa – 11.82%, density 2300.36 kg/m3 – 9.24%. The most optimal content of the micro-filler on the basis of wollastonite for producing the efficient fine concrete with high physical-mechanical characteristics is 10%.
