Abstract

The increase of amount of plastic glass waste, gives an idea to use it as an additional material in concrete. It expects to decrease the urban waste problem and to improve the mechanical properties of concrete. The objective of this experimental research is to study the effect of usage crushed polypropylene (PP) plastic waste in compressive, tensile, flexural and shear strength on normal concrete with fc’ = 25 MPa. The proportion of crushed PP added to normal concrete are 0.10; 0.15 0.20; 0.25; 0.30; 0.50; 0.70; 1.00; 2.00 and 3.00% in fraction volume. From the compressive test in age 7 days, there is 5% of compressive strength improvement by adding 1.00% of crushed PP plastic on normal concrete. From the splitting tensile test in age 7 days, there is 11% of tensile strength improvement by adding 0.5% of crushed PP on normal concrete. From the flexural and shear tests in age 28 days give respectively 17% and 43% of flexural and shear strength improvement by adding 0.5% of crushed PP plastic on normal concrete.
