Comparative study on direct shear strength of sandy clay soil with glass fiber reinforced sandy clay soil for sustainable construction

Soil is the important base for the construction to improve the soil properties and strength of the soil. The glass fiber is added and compared cohesion and angle of friction of sandy clay soil and glass fiber reinforced sandy clay soil. Materials and Methods: In the present study the direct shear strength test is used to know the cohesion and angle of friction of the sandy clay soil and glass fiber reinforced sandy clay soil (1.5% glass fiber). A total of 36 samples (18 sandy clay soils samples and 18 glass fiber reinforced sandy clay soil) were tested. Results: Independent Sample T-test on sandy clay soil and glass fiber reinforced sandy clay soil. The obtained significance for cohesion is 0.197 (p>0.05) and for angle of friction is 0.001 (p
