Abstract: This technical paper serves to provide engineering guidance from the perspective of optimization and valance as the engineering tends to lean on conservatism for practitioners. Thus, the ultimatum is to research and produce some sustainable foundation design techniques for both unpiled-raft and piled-raft foundation structures.

Abstract: Polyethylene Terephthalates (PET) is most of plastic container normally being discarded and resulted in environmental pollution. One of a better means is to recycle PET in concrete. This paper describes an experimental investigation of the relationship between tensile strength and compressive strength of concrete containing Ring type of waste PET bottle (RPET) fibre. The RPET were obtained by simple mechanical cutting from waste bottles into 5 and 10 ± 1 mm in width of the waste bottle to produce the RPET-5 and RPET-10 fibre. Comparative studies were conducted with two different water-binder ratios which are 0.45 and 0.55. Concrete containing with 0.0%, 0.25%, 0.50%, 0.75%, 1.00%, 1.25%, and 1.50% volume of RPET fibre content were produced in cylindrical specimens in 150 mm . All specimens were tested at the age of 28 days. It has been found that ultimate tensile strength of RPET concretes were greater compared to normal concrete. Incorporation RPET fibre in concrete has produced and e
