Abstract


Abstract. Purpose. Study of the structure, physico-chemical and mechanical properties of various clay soils for erath-concrete industrial production. Methodology. To achieve this goal, the authors have determined the basic physical properties of clay soils in accordance with Ukrainian State Standard 2.1-17-2009. Findings. It is established that in order to obtain high quality concrete products and structures it is necessary to use clay soils of medium dispersity, with low shrinkage and swelling, in the mineralogical composition of which kaolinite predominates, in the absence of organic impurities. If the indices of certain properties are not satisfactory, it can be modified by the introduction of appropriate chemical or mineral additives. It has been established that the investigated clay soil has a plasticity number in the range of 8.8-11.4 and refers to a variety of loams. It was revealed that this kind of soils is best strengthened with cement in an amount of 14-20%, depending on the required strength of the concrete. Originality. The further ideas about the role of various properties of clay soils on the quality of concrete products and structures have been received. Practical value. The basic physical properties of clay soils of the Dnieper region have been determined. The ways of its most effective strengthening by astringents and the manufacture of concrete products and structures have been revealed.
