Study of Shear Strength Behaviour of Soil With Kaolinite Mixture
Abstract: An experimental testing program was undertaken for evaluating the effect of kaolinite on the strength properties of locally available sand and soil. Strength depends principally upon the content of (1) water, (2) clastic materials and (3) plastic materials. Soils are primarily of two types (1) cohesionless soils in which the strength this produced mainly by the friction of clastic particles against one another, and (2) cohesive soils in which the …

Effects of Reinforcing Elements in Soil Reinforcement
Abstract: The inclusion of reinforcing elements in a soil mass improves its geotechnical properties. The principle behind soil reinforcement is that the reinforcing elements absorb the tensile load and shear stress within the reinforced structures and hence prevent the shear failure and settlement. The friction developed between the interface of soil and reinforcing element improves the properties of soil. Different types of natural and synthetic fibers have been used in various …

Study of Balanced Energy Absorbing Material for Structural Applications.
Abstract: The ballistic execution of "smart-sized" S2-glass fiber fortified epoxy was assessed in correlation with network perfect, framework semi-good and lattice contradictory estimated materials. The smart size is a detailing intended to give rate-subordinate conduct. The brilliant estimated material was appeared to show rate subordinate changes in interlaminar shear quality and mode I interlaminar break sturdiness testing; the ballistic execution of the material was enhanced just marginally over perfect measured materials. …
