Đặc tính không phân hủy sinh học của chất thải nhựa gây ô nhiễm môi trường, nên việc tái sử dụng chất thải nhựa như một nguyên liệu tiềm năng để thay thế một phần cát, một trong những cốt liệu mịn để tổng hợp bê tông. Polyethylene therephthalate (PET) được sử dụng rộng rãi. | TNU Journal of Science and Technology 227 08 458 - 466 THE EFFECT OF MIXING RATIO OF PET WASTE PLASTIC FROM BOTTLES ON BASIC PROPERTIES OF CONCRETES Nguyen Dang Khoa Nguyen Vo My Quynh Phan Thi Kim Anh Van Lang University ARTICLE INFO ABSTRACT Received 07 5 2022 The non-biodegradation of plastics waste pollutes the environmental which brings to the reuse of plastic waste as a potential material to partly Revised 30 5 2022 replace sand one of the fine aggregate for the preparation of construction Published 31 5 2022 concrete. Polyethylene therephthalate PET is widely used. In this study PET plastic waste was used at 3 6 9 12 w w relatively to sand KEYWORDS in the prepared concrete grade M350. After that the obtained concrete was evaluated the effect of mixing ratio of PET waste plastic on the basic PET plastic waste properties including slump compressive strength and water absorption of Concrete concrete after 14 and 28-day curing. As results the slump values of the Compressive strength plastic-mixed mortal decreased sharply when the amount of PET plastic increased from 3 to 12 as 35 to 92 compared to the control sample. Plastic aggregate Similar results were obtained when measuring the water absorption. Mechanical properties Compressive strengths after 14-day curing were decreased as and Mpa as the replacing ratio of sand was 3 and 12 respectively. It was noted that the 28-day compressive strength value of the plastic- contained concretes were decreased as Mpa when plastic waste was mixed at 12 relative to sand. It may due to the compatible difficulties of mixed material as plastic waste instead of conventional sand causing the reduction in compressive strength and enhancement of water absorption after 28-day curing.
