Abstract

High quality concrete as a construction material more widely used, but the higher of the concrete quality
will cause ductility properties of concrete decreases. One way to decimate the mechanical properties of high
strength concrete is to provide additional materials in the concrete mix. This study aimed to determine the
effect of plastic rope in the concrete mixture. Technical properties of concrete under review due to the
addition of plastic rope to concrete is compressive strength. The method used in this research is to make a test
piece for later testing compressive strength. The test object is created by the addition of plastic rope along the
5 cm, 7 cm and 10 cm as much as 0.5% by weight of coarse aggregate. Specimens were made for each
variation is 3 pieces and will be tested on the concrete age 7 and 28 days. The planned results in this study is
the high quality concrete compressive strength of 55 MPa at the age of concrete 28 days. From the research
that at the age of concrete 28 days minimum compressive strength of concrete specimen contained in the
concrete with the addition of 5 cm plastic ropes of 11.75 MPa or 21.36% of the compressive strength of
concrete plans. The maximum concrete compressive strength at 28 days there on the concrete specimen with
the addition of plastic rope 7 and 10 cm at 12.14 MPa or 22.07% of the compressive strength of concrete
plans.
