Experimental Study on Light Weight Concrete using Plastic Waste as a Partial Replacement of Fine Aggregate

Abstract

Waste from plastic materials is outstripped due to the growth of industrialization and urbanization. Plastic materials are non-biodegradable; decomposition is not possible all the time. Recycled plastic materials by using concrete, will be a great deal for plastic management for a certain period. Aims to measure the optimum percentage of plastic in concrete without a reduction in concrete strength. The goal of this experimental investigation is to clarify the shear cracking behavior of reinforced concrete beams with the combination of fine aggregates such as Recycled Polyethylene Terephthalate (RPET) and Polypropylene (PP) in the weight fraction of fine aggregate. Using the provision of Mix Design ACI 211.1-91, the M28 concrete grade was created. The mechanical characteristics and shear performance were examined for concrete made utilizing various hybrid combinations. Plastic materials were collected and passed through a No-4 sieve (4.76mm). Reinforced concrete beams(750mm*150mm*150mm) and cylinder specimens of concrete (100mm diameter and 200mm height) were made by the mixture of plastic materials as a percentage of total fine aggregate in the mix (0%, 2%, 4%, 6%, 8%, 10%). The beams were conducted for the shear capacity test and the cylinder specimens for the compressive test and tensile splitting test. The beams are reinforced with two 12 mm steel bars in the tension zone of the beam with a proper clear cover. The experimental findings demonstrate which partial replacement of fine aggregate produced the best outcomes and also analyze shear behavior and fracture development.

Assessing the Performance of Melted Plastic as a Replacement for Sand in Paving Block

“…Additionally, various forms of plastic are also used as a substitute for materials, such as plastic pellets, chopped plastic, and melted plastic. Mozumder et al [11] used plastic pellets as a substitute for sand with variations of 0%, 2%, 4%, 6%, 8%, and 10% by weight of sand. The highest compressive strength was achieved when adding 4% plastic, and the compressive strength decreased significantly when adding 8% and 10% plastic.…”
