| dc.description.abstract | This paper presents the results of investigations of permeable soils strengthened with modified polymer resins in laboratory and field tests over a period of 1 year. Comparison was done of properties of no modified urea-formaldehyde resins with properties of modified urea-formaldehyde resins. Such properties of solution of resins have been investigated: density, viscosity, pH (alkalinity level), evaporation of free formaldehyde from solution. During the next stage of investigations properties of alluvial medium dense sand stabilized with no modified and modified resins have been compared. Such properties of strengthened soil have been investigated: uniaxial strength, evaporation of components of resin from soil, time dependent strength of soil in air and water medium. Results of field tests confirmed the results of laboratory tests. Addition of active components to urea-formaldehyde resins increase density and pH of solution of urea-formaldehyde resin, decrease viscosity. Uniaxial strength of sands stabilized with polymer resins is highly time dependent. | eng |
