Abstract:
Study deals with Young’s Modulus or Modulus of Elasticity of Laterite Soil-bamboo mixture. Bamboo fibers are used in the soil. Four different mixes such as natural laterite soil, soil + 1{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} bamboo (bamboo length 0.5cm,1.0cm & 1.5cm), soil + 2{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} bamboo(Bamboo length 0.5cm,1.0cm & 1.5cm) and soil + 3{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} bamboo (Bamboo length 0.5cm,1.0cm & 1.5cm), respectively have been considered in this study. All the test samples have been prepared at maximum dry-density and cured under normal atmospheric condition for 7, 14, 21, 28, 35 and 42 days and also in oven at controlled temperature of 500C for 2-days in the laboratory with a view to determining the equivalence of oven curing in terms of days of normal curing comparing Modulus of Elasticity. “Modulus of Elasticity at 50 {6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} failure stress” is considered as Modulus of Elasticity value of any soil sample. It is noticed that the gain in Modulus of Elasticity of Laterite soil-bamboo mixture is more if the more bamboo fiber percentages are used in the soil. On the other hand Modulus of Elasticity depends on days of curing. Modulus of Elasticity of soil bamboo mix is increasing with increase of curing days. But Rate of change of Modulus of Elasticity up to 28 days is more but rate of change of Modulus of Elasticity for 28 to 35 days or 35 to 42 days almost negligible.
