ANALISIS KUAT TEKAN BETON MODIFIKASI POLYETHYLENE TEREPHTHALATE (PET)

Abstract

Concrete is one of the most commonly used materials in the world of construction, both simple and complex. Concrete
is the most widely used construction material as a building material so it is necessary to know the classification and
characteristics of the material or construction material to be used. The use of waste in concrete mixtures is a trend in
the development of concrete today because it helps reduce environmental pollution, by utilizing and processing solid
waste generated by industrial waste and municipal waste, as well as reducing the use of natural materials which are
increasingly limited in number. The most abundant waste is polyethylene terephthalate (PET) plastic. Therefore, it is
necessary to use PET plastic as an effort to create an alternative technology that is innovative enough to improve the
quality of concrete by using fiber concrete. So this research method uses variations of PET as much as 0.1%; 0.25%;
and 0.4% as a substitute for some fine aggregates. The plastic was cut or chopped with a length of 5 cm and a width
of 1-3 mm. The results showed that concrete with PET plastic fiber increased up to 12.96% compared to normal
concrete.
