Mix concrete practical 1pc: 2 ps: 3split, people used to build houses, has a specific
gravity of 22-24 kN/m3. Density large concrete impact severity construction was,
blend ingredients lightweight aggregates to produce lightweight concrete. One is
used for lightweight aggregate material is waste plastic bags. Because the amount
of waste plastic bags or piled carelessly discarded in landfills (TPA) impact of
environmental pollution. This paper presents the study of the flexural strength and
buckling the use of waste plastic bags as a partial replacement of coarse aggregate
mix. The percentage of coarse aggregate replacement with waste plastic bag of
approximately 30% is expected to produce flexural strength and buckling optimum
reinforcement variation different. Bending beam size 10/15 cm length of 70 cm,
variations in the tested reinforcement bending strength. While buckling strength
using the dimensions of length 70 cm 10/10 with a variety of symmetrical and non
symmetrical reinforcement. Effective capacity reinforcement ratio press the tensile
reinforcement that generates maximum torque is 66.67%.
