As a result of some recent sudden building collapses, the use of concrete with improved properties has become necessary. This study produced concrete using plastic box waste (PBW) from boxes used to store and transport vegetables and fruits. The particles resulting from these boxes were used to partially replace 5%, 10%, 15%, 20%, 25%, and 30% of the sand. The produced concrete was subjected to tests of compression, density, modulus of elasticity, and impact resistance. The impact resistance significantly improved from 18% to 155% in the first cracking and from 14% to 67% in failure cracking as the replacement of sand with PBW increased from 5% to 30%. The density was also reduced by 3.43% to 10.33% for the same range of replacement. Decreased compressive strength and elastic modulus were observed, but both values remained acceptable for structural concrete.
