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 ...

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 ...
