Laboratorial researches of soil



The research of soil by laboratory methods reflects in itself the complex of works on the receiving engineer-geological information about composition and properties of soils. Methods are varied in a certain physical, mechanical, chemical and physic-chemical properties of soils:
  • to determine natural humidity;
  • to determine the density of particles (skeleton) of soil;
  • calculation of porosity;
  • methods on determining of borders of and number of plasticity (consistency);to determine density;
  • granulometric size composition
  • ability to subsidence and volumetric swell of subsurface rock and following determining type
  • Resistant movement of soil
  • to determine deformational compositions of soil;
  • strength of soil under uniaxial compression;
  • to determine the strength of soil under uniaxial compression
  • to relative subsidence and primary subsidence pressure;
  • to determine the natural angle of slope.
  • to determine the composition and proprieties of water-soluble salt;
  • to determine the carbonates in soils;
  • to determine the total composition of organic substances;
  • to determine the stickiness of the soil;
  • the permeability of the soil, to determine swelling;
  • to determine the macerate and erosional features of subsurface rock;
  • the level of aggressiveness of soils to concrete, to colorful or black metal.
In our laboratory are defined the mechanics of soils, determining characteristic of durability and deformational compositions of soil
