Методика оценки качества защитно-декоративных покрытий цементных бетонов

The technique of assessing the quality of the painted surface of cement concrete. The technique is based on acceptance sampling quality and is to determine the average and standard deviation (SD) of quantitative assessments of various quality parameters and calculating the real defect level (percentage of defective surface of the total area) for each indicator. Lists the properties of the painted surface that determine its quality. The algorithm performance The formulas for calculating the defect level. The critical fraction nonconforming surface area coverage for individual properties. The formula for calculating the number of sites. It is shown that knowing the real value of the defect level of the individual properties-qi, compare them to the values specified in the requirements and conclude as a covering-ment on individual properties.
