Light Structurally Thermal Insulating Concrete with a Wide Range of Applications from Recycled Waste Polypropylene Container

Abstract

One of the most pressing issues of the 21st century in the field of construction and ecology has become the use of secondary production waste. A promising way to solve this problem could be the production of lightweight structurally thermal insulating concrete with a wide range of applications from recycled waste. We examined the use of filler, which is a cheap secondary waste in the production of polypropylene containers for the production of structurally thermal insulating concrete. The resulting aggregate is composed of blue or transparent granules, predominantly triangular and rectangular. Polypropylene aggregate exhibits a water absorption rate of 8.6% and possesses a density of 1.06 g/cm3. Research has demonstrated with a volumetric weight ranging from 1395 to 1805 kg/m3, while achieving concrete grades ranging from M25 to M250 in terms of compressive strength. In our assessment, the utilization of light concrete with a volumetric weight falling within the range of 1625 to 1805 kg/m3, and conforming to compressive strength grades ranging from M100 to M250, represents the most optimal choice for the construction of buildings and structures, making it a highly favorable option for various construction applications.
