Influence of Calcite Particles on Mechanical Properties of Grouted Sandy Soil

Chemical and mineralogical content of sands has very high influence on uniaxial compressed strength of grouted soils. In this paper influence of calcite particles in sand on mechanical properties of grouted with urea-formaldehyde resin sandy soil is described. Long-lasting experimental laboratory investigations are executed. In result of our investigations we make conclusion, that addition of calcite particles in sandy soil decreased compressed strength of grouted soil specimens observed in time of 3 months.
