Sustainable consumption of resources, focuses on the capitalization of existing waste and prevention of generating new ones, therefore adopting the Sustainable Development principles. The increase in the utilization of sand from rivers for various construction purposes, which also disturbs the environment can be considered another damaging factor for the environment. Recycling of garnets and their use as replacement for sand aggregates could provide an ecological solution for the production of the alkali-activated fly ash-based geopolymer binders. The aim of this paper is to present preliminary results regarding the use of spent garnet as replacement for sand aggregates in the production of alkali-activated fly...

In this work, geopolymer materials produced using fly ash and marble dust or blast furnace slag were studied to assess the influence of these substitutions on the performances of the final product. Geopolymer materials have been characterized by physico-mechanical methods, FTIR spectroscopy and microscopically. The analysis of the results indicates the reduction of the mechanical strength performance by substituting the fly ash as the raw material.

In terms of environmental impact, the waste recycling and reuse from construction and demolition activities, reduce the occupied authorized landfills area. Also, by recycling and reuse, it is achieved an economy of non-renewable natural resources. From the economic point of view, the use of recycled materials in place of the natural resources, that reach extremely high costs, it becomes, from one year to another, a solution increasingly more advantageous. This paper presents some opportunities to recycling various waste (glass, polypropylene, filler, ceramic blocks) by using them in the concrete production. The experimental researches have revealed the opportunity to reconsider the four waste studied types, by introducing them as raw materials in the concrete preparation. Moreover, there is the possibility to obtain some types of concrete with special...
