Industrial Automatic Control Systems and Controllers Annotation << Back Computers Automation of the Procedure for Determining the Content the Clay Lumps in Sand for Construction Works T.G. Samkharadze, A.N. Pudovkin, D.F. Sinitsyn, V.V. Sokolova, V.A. Ryazanova, A.A. Parfenova The paper considers the application of a computer program to the calculations of determining the content of clay lumps in sand for construction work. This program automates the existing calculation method with the possibility of accelerated processing of the received results. The program functionality is to determine the content the clay lumps in model and sand samples for construction work through partial residues on sieves. Fragments of the program code are presented. The calculation program will accelerate the laboratory processing of the results obtained, as well as facilitate work directly at enterprises for the production of concrete and reinforced concrete products and construction sites. Keywords: automation of calculation; clay lumps; sand for construction work. DOI: 10.25791/asu.7.2023.1446 Pp. 16-22.
