Influence of major lowland water basins on geotechnical status of loess soils

BARANOVA Margarita N., MALTSEV Andrey V., VASILYEVA Daria I. 9-14 p.

The prevalence of loess soils in North Eurasia steppe zone causes their frequent use as building foundations. In this regard their geotechnical features are of particular importance. In European part of Russia loess soils are widespread in mid-Volga region which present at the moment tandem reservoir system created more than 50 years ago. In reservoir area major lowland rivers show rapid increase of groundwater level that has negative consequences in the case of loess soils. In Samara region there are two great lowland water basins on Volga river (Kuibyshev and Saratov Reservoirs) which have a great impact on environment. Loess soils geotechnical features, geological processes, material composition and microstructure as well as their changes in underfl ooding are described.Underfl ooding infl uence on loess soils in urban development conditions are studied.

Slag-lime binders are diffi cult in-use because of curing time and its infl uence on concrete brick durability. One of ways of sett ing time regulation lies in introduction of some stone-cutting waste in blast-furnace grained slag before grinding. The studies of stone-cutt ing waste infl uence on curing time, durability and structure formation of slag-lime binder and concretes on its basis are able to show mechanism of curing time regulation and it will work to correct technological parameters of construction items production. The phase composition is studied with help of the diff erential thermal, x-ray diff raction and microstructural analyses.
