observation of specific submicron components behavior after specific exposition is applied.
It should be emphasized that the diversity of atomic force microscopy techniques (AFM) allows one to perform imaging of mechanical, magnetic, electrical, thermal and optical properties of the surface [ 1 ]. A number of observations of the morphology change due to the light/temperature or electrical field [ 6 – 10 ] have been performed. One has to be aware that significant variations of certain properties due to the local inhomogeneities of material can become an obstacle during the

affected by water content, cement content and curing time.
– The increase in the water content significantly increases the shear strength of the sand-cement mixture due to the hydration of the cement, and reduces the deformability of the sand-cement mixtures (by increasing the dilatant character).
– The addition of cement in the sand increases the shear strength considerably; it not only improves the shear strength of the soil, but also provides diversity in the resistance against the deformations imposed loads, which can result in a minimization of expansion
