Method of assessment quality protective and decorative coating concrete cement

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. The formulas for calculating the defect level. The critical fraction nonconforming surface area coverage for individual properties.
