Effect of LDPE raw material on strength,corrosion and sorptivity of concrete

Many researchers focused on effect of low density poly ethylene (ldpe) on bituminous pavements or concrete to modify the strength and ductility in view of reusing the abundant quantity of non-degradable ldpe material available. it also reduces the use of bituminous materials and disposal problems of such waste material. developing countries are moving towards construction concrete pavement or converting bituminous pavements into concrete pavements. hence in this paper an attempt has been made to study the feasibility of using ldpe raw material itself as a modifier in cement concrete with a characteristic compressive strength of 20 mpa. present study focuses on effect of addition of ldpe raw material (3,4 and 5%) under different temperatures (70°c,80°c and 90°c) and duration of thermal curing (4,8 and 16 hours) on compressive strength,corrosion resistance and sorptivity. it was inferred from the results that,addition of ldpe raw material considerably increases the compressive strength,resistance against corrosion and permeability. results also revealed that concrete with 3% ldpe modifier for 80°c with 4 hours of thermal curing was found to be optimum. © school of engineering,taylor’s university.
