[EN] Waste management is a crucial issue facing modern society. The generation of sewage sludge is increasing annually due to the
urbanization and improvement of sanitation systems of cities. The construction sector has ...
[EN] Production of Portland cement requires a large volume of natural raw materials and releases huge amounts of CO2 to the atmosphere. Lower environmental impact alternatives focus on alkali-activated cements. In this ...
[EN] The ceramic sanitary-ware market generates large amounts of waste, both during the production process and due to construction and demolition practices. In this paper, the effect of different amounts and calcium sources ...
