QUALITY CONTROL OF DISPERSED COMPONENTS POWDER-ACTIVATED CONCRETE WITH THE HELP OF SHUKHART'S CARDS

Abstract

In the construction industry, cement concretes are the most widely used building material. New generation materials with increased strength and durability are used in the construction of critical facilities. Special requirements are imposed on such concretes to ensure their quality. The issues of control and quality of powder-activated concretes of a new generation at the stage of preparation of their constituent components are considered. Author made in the article the analysis of the classifier data for the developed system of quality control (QC) based on Shewhart control charts. For implement an effective classification of critical situations we justified target-conformity application of support vector. We accumulated the base of possible solutions in special cases when process of cement production go out from control limits. For pro-programmatic implementation of support vector we used library application LIBSVM. We described procedures for the preparation of the accumulated data for training models of SVM. We determined optimal parameters of created models nuclei to ensure accurate classification. We created SVM models for all monitored parameters. We created HMI display effective solutions to prevent critical situations for the operator.
