DEVELOPMENT OF ENVIRONMENTALLY SAFE, ENERGY EFFICIENT CELLULAR CONSTRUCTION MATERIAL CORRESPONDING TO THE PRINCIPLES OF GREEN CONSTRUCTION

Foamed glass is one of the most energy efficient construction materials. However, the existing technologies of foamed glass manufacture do not correspond to the principles of green construction because a special sulphate glass is used, produced from natural raw materials, and it causes emission of pollutants at all stages of the life cycle of the material. The resource and energy-saving technology for producing environmentally safe energy-efficient foam glass based on off-grade glass cullet, which is a component of solid municipal waste, has been developed, substantiated and implemented. In solving a particular problem of foam glass production, an algorithm of development of an environmentally safe building material based on or with addition of production and consumption wastes was proposed and approved. This algorithm is consistent with the principles of green construction. Subject: development of the technological scheme of manufacture and recycling of energy efficient cellular material corresponding to the requirements of ecological safety at all stages of its life cycle; proposition of an algorithm that solves the general problem of development of environmentally friendly construction materials and conforms to the principles of green construction. Materials and methods: analysis of existing technical solutions for manufacture and recycling of foam glass from the viewpoint of green construction principles and proposition of alternative environmentally friendly solutions. Results: as a result of elimination of the drawbacks inherent in the existing foam glass at all stages of its life cycle, technical solutions that ensure environmental safety of the material were substantiated. Conclusions: the results can be used for development of construction materials corresponding to the principles of green construction.
