Statistical Analysis of Quality of Autoclaved Gas Concrete in Tasks of Improving the Efficiency of Its Production

Results of the complex statistical analysis of the quality of gas concrete made for a year period of operation of the enterprise equipped with new foreign technological equipment are presented. Autoclaved gas concrete of average density D500 and strength grade B2.5 was used as an object of the statistical analysis, because concrete products of this brand are the most mass product which is the main demand of the consumer. It is revealed that the variability of properties identifies the need to ensure the excess reserve of production quality, for strength primarily. The degree of correlation interconnection of the key parameters in technology and basic properties of the gas concrete has been evaluated qualitatively. The intercon­ nection between the degree of variability of parameters of the technological process and excess quality of production, the probability of spoilage appearance are revealed statistically reliably. The ways of improving the production efficiency due to the use of the available reserve of products quality as well as by rationalization of technological parameters as a means of reducing production expenditures are proposed.
