Cracking Propagation of Reinforced Concrete Using Polyethylene Terephtalate (PET) Bottles as Fine Aggregate

Abstract:

This paper describes the experimental investigation on the cracking propagation and pattern of reinforced concrete beam containing PET aggregate as fine aggregate that subjected to shear. The replacement ratio of 25%, 50% and 75% were used in this study. Prior to structural test, the materials properties which include the compressive strength test, split tensile test, Modulus of Elasticity test and density were determined. The result obtained showed that the inclusion of PET aggregate reduce the initial loading cracks to 27%, 38% and 46% compared to their corresponding normal concrete ; thus affecting the shear resistance of the structural beam especially the ability of the beam to resist shear via interface friction and interlocking between aggregate.
