The factors influencing on the soil-concretes quality

Construction of ecological houses at the lowest cost of material and labor resources, based on the concept of sustainable development has become a priority in many countries, including Germany, the US and Russia [11, 12, 18]. Buildings constructed from soil-concrete materials, are energy efficient, environmentally friendly, more economical than traditionally used concrete. Pavement in our country also needs urgent renovation and equipment of road pavements ubiquitous cheap raw materials, as which can act reinforced cementitious soils. However, the wide dissemination of the material prevents manufacturers have formed a stereotype that soil containing materials are chemically bonded type of short-lived, low water and frost resistance, insufficient mechanical strength, high labor-intensive during construction. For exceptions to this problem requires a comprehensive approach that takes into account the diversity of the main factors that affect the quality of the soil-concrete, competent management which will eliminate the above disadvantages of the material. Analysis of publications. In recent years, there is a growing interest in the soil-concrete for various purposes. But as the analysis of publications, most researchers solve the problem of improving the quality of soil-not as a complex, and in the context of a particular one or more of the factors considered by them. Among the works of the near abroad can be identified [1, 5, 7-10, 14, 15, 17] and other foreign countries [11, 18-21]. Aim. The article discusses various factors, the most significant effect on the quality of soil-concrete, with proper management that is possible to obtain an effective competitive material with a wide range of applications. Conclusion. The main factors affecting the performance characteristics of soil-and their quality can be divided into two groups: the technological and chemical, physical and chemical. The first group includes: soil-moisture mixture, the concentration of the binder in it, the degree of homogeneity and compaction soil-concrete mixture, the duration of curing the compacted material and the temperature and humidity conditions of the environment; second - mineral and granulometric composition of the soil, their organic components, the reaction medium. An integrated approach to the issue that takes into account the specifics of clay soils can obtain high quality competitive materials based on them - soil-concrete.
