Evaluation of mortars with combined use of fine recycled aggregates and waste crumb rubber
Letelier, Viviana; Bustamante, Marion; Muñoz, Pedro ; Rivas, Sebastian; Ortega, Jose Marcos (Journal of building engineering, 2021)The use of secondary materials from waste or debris is a strategy that has been considered a starting point for the successful transition to the circular economy model. Globally, waste from concrete debris like disused ... -
Feasibility of using paper pulp residues into fired clay bricks
Muñoz, Pedro ; Letelier, Viviana; Zamora, D.; Morales, M P (Journal of Cleaner Production, 07/2020)In accordance with global estimations, approx. 15 million tons of residues are yearly generated from paper and pulp industry, which are traditionally used as biofuels or just disposed in landfills. However, residues ... -
Fired clay bricks made by adding wastes: Assessment of the impact on physical, mechanical and thermal properties
Muñoz, Pedro; Morales, M P ; Letelier, Viviana; Mendivil, M A (Construction and Building Materials, 10/2016)The addition of residues into clay matrix has been widely reported and reviewed during last decade. The heterogeneity of wastes and the lack of detailed information make difficult to provide an overall framework for comparing ... -
