Durability of geothermal grouting materials considering extreme loads
Indacoechea-Vega, I,; Pascual-Muñoz, P.; Castro-Fresno, D.; Zamora-Barraza, David (2018)The concern about the massive use of the non-renewable and very limited fossil fuels together with the well-known effects of the global warming makes it more necessary the efficient use of the current forms of renewable ...

Effect of freeze-thaw and wet-dry cycles on the mechanical and hydraulic characteristics of geothermal mortars
Zamora-Barraza, David; Vilches-Tapia, Juan; Sierra, F.; Bravo, H. (2020)The appropriate performance of a vertical geothermal exchanger depends not only on the thermal properties of the elements that composed it, but also on the close contact between them to ensure the heat transfer. This contact ...

Experimental analysis of enhanced cement-sand-based geothermal grouting materials
Pascual-Muñoz, P.; Indacoechea-Vega, I; Zamora-Barraza, David; Castro-Fresno, D. (2018)Nowadays, Ground Source Heat Pumps (GSHP) are achieving significant efficiencies, mostly because of the development of their electromechanical components. However, concepts such as the technical performance of the grouting ...

Feasibility of using paper pulp residues into fired clay bricks
Muñoz, P.; Letelier, V.; Zamora-Barraza, David; Morales, M.P. (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 ...

Influence of early colour degradation of asphalt pavements on their thermal behaviour
Pascual-Muñoz, P.; Castro-Fresno, D.; Carpio, J.; Zamora-Barraza, David (2014)Environmental goals such as the reduction of fossil fuel consumption or greenhouse gas (GHG) emissions through the development of new renewable energy sources have led to the emergence of the so called asphalt solar ...

The effect on the compressive strength of concrete produced by the incorporation of boiler-calcined biomass ash into sand from the Maule River, Chile
Schmidt, W.; Vilches-Tapia, Juan; Zamora-Barraza, David; Bustamante, M.; Cofré, R. (2020)The pulp industry generates large amounts of wood biomass ash (WBA) as waste, which causes economic and environmental problems. However, WBA has pozzolanic and cementing properties that can complement cement in concrete ...
