Heading: Raw materials

The biochemical nature of the gley formation process during aging of clay materials (GM), the factors of its occurrence, identification methods and its influence on the properties of GM are considered. It is shown that among the necessary factors are the moisture content of GM, the content of organic matter and natural microflora, as well as maintaining the optimum temperature during the aging period. To identify biochemical processes and determine the optimal duration of GM aging, a comprehensive assessment is proposed using color characteristics, the redox state of the medium and chemical criteria based on the ratio of forms of iron compounds. Tab. 1, bibliography: 23 titles.
