Hrano N. Soil Materials Based on Mineral Binding Materials, Modified by Complex Admixture

Object - Soil Materials modified mineral binders, active mineral complex and chemical additives used as foundations of roads, buildings and structures for various agricultural purposes; goal - the development of theoretical ideas about the processes of structure formation in loamy soils in the presence of mineral binders, active mineral admixtures and additives superplasticizer, and development on this basis of fixed soil compositions with increased strength, operational reliability and durability for use as foundations of roads, buildings and structures for various agricultural purpose; methods - X-ray phase, IR spectroscopy, electron microscopy, physical and mechanical; Novelty - developed theoretical understanding of the processes of structure formation in loamy soils with lime or cement fixed with blast furnace slag and add superplasticizer; The introduction of impurities superplasticizers anionaktyvnyh surfactants together with reinforcing component facilitates peptization of soil aggregates and the formation of more number of contacts between individual particles; The scheme was first formation elektrohomohennyh (between the eponymous charged soil particles and / or layers adsorbed counterions ) and elektroheterohennyh (between oppositely charged surfaces of soil particles, slag, crystalline and gel hydration products ) contacts in clay soils, including fortified mineral binders that increase strength and water resistance, reduce swelling and deformation of soil; proved that the addition of complex chemical additives containing superplasticizer on melaminsulfovaniy or naphthalene-based and accelerator type thiocyanate or sodium thiosulfate in Soil Materials composition based on loamy soil and cement or lime and ground slag provides a slowdown of the growth of germs Ca(OH)2 and increase their dispersion, and the pores are characterized by smaller size and volume compared to samples of the soil; scope - a new building material in the construction and reconstruction of the foundations of roads, buildings and structures; in the learning process.
