OPTIMIZATION OF THE COMPOSITION OF THE ADDITIVE OF STABILIZED HIGHLY DISPERSED WOLLASTONITE USING A COMPUTER ALGORITHM FOR FINDING EXTREMES

Abstract

The article considers the optimization of the content of the components of the additive of stabilized highly dispersed wollastonite using a developed and patented computer algorithm for finding extreme coordinates of the dependencies of the mechanical characteristics of fine-grained concrete Extr.sce and Interp.sce based on the Scilab engineering and scientific computing environment. The developed programs allow determining the best combination of components and technological parameters for obtaining an additive to identify the optimal value of the desired indicator of the final characteristics of fine-grained concrete. The search for the maximum value of the strength indicators of fine-grained concrete is performed depending on the combination of the initial components of the modifier based on highly dispersed wollastonite, as well as the time of their ultrasonic dispersion with the output of visual data processing models in the form of contour and 3d graphs of the interpolation surface. As a result of the simulation, it is found that the additive shows the most effective result with a wollastonite content of 5 g/l, in which a modifier M with a concentration of 2.1 ml/l is used as a suspension stabilizer, while the ultrasonic dispersion time is 5 minutes. The developed additive of optimal composition contributes to the production of modified fine–grained concrete with a bending strength of 6.8 MPa and compression strength of 58.5 MPa
