Abstract

Technology of Utilization of Polypropylene Waste and Wastewater Sediments by Production of Building Blocks

Highlights

  • The waste utilization for the production of building materials is a modern eco-efficient solution in order to solve the environmental problems of environmental pollution and to reduce the cost of raw materials in construction mixtures, which will lead to the cost reduction of final products (Trus I.M. et al 2017, Ivanenko et al 2021, TrusI. et al 2020)

  • A vital task for the introduction of wastewater sediment and polypropylene disposal technology is the determination of the criteria according to which the time that went on heating, melting of the feedstock mixture and binding of its components would be the shortest

  • Along with the process of thermoplastic melting under periodic stirring of the feedstock mixture, the binding processes of wastewater sediment with polypropylene took place

Summary

Introduction

The waste utilization for the production of building materials is a modern eco-efficient solution in order to solve the environmental problems of environmental pollution and to reduce the cost of raw materials in construction mixtures, which will lead to the cost reduction of final products (Trus I.M. et al 2017, Ivanenko et al 2021, TrusI. et al 2020). Cement-free building blocks of steel and blast furnace slag were studied in terms of density, water absorption, compression strength, resistance to freezing and thawing (Mahoutian et al 2016, Tan et al 2021, Mahoutian and Shao 2016). They show better mechanical properties than commercial cement blocks, and the cost of slag blocks manufacturing in mass production will be lower (Srivastava et al 2021, Ghouleh et al 2015, Mahoutian et al 2018)
