Lime silica bricks are one of the most predominant elements in construction and demolition waste, contributing significantly to the total solid waste produced worldwide. In Peru, the direct disposal of this waste in landfills prevails due to the lack of management alternatives and the lack of knowledge about sustainable options to use these materials. Simultaneously, the high CO2 emissions produced by the cement industries contribute substantially to global greenhouse gas emissions, giving rise to climate changes, melting of the Arctic ice, alterations in the biodiversity of animals and plants, droughts and others. phenomena. Recently, much research has been conducted on the use of supplementary cementitious materials to decrease cement production. This study focuses on evaluating a sustainable concrete by incorporating crushed calcareous silica brick waste and basalt fibers. To do this,...
