Título: Caracterización mecánica de morteros de cemento Portland con breas de petróleo y de alquitrán de carbón Autor/es: Alcaide Romero, Juan; García Alcocel, Eva María; Vilaplana Ortego, Eduardo; Cazorla Amorós, Diego; Garcés Terradillos, Pedro Resumen: En este artículo se presentan datos experimentales de resistencia a flexión y a compresión de morteros de cemento Portland con adición y sustitución de breas de petróleo y de alquitrán de carbón, que son subproductos de la industria del carbón o del petróleo. Los materiales estudiados son breas de alquitrán de carbón A (BACA) y B (BACB), y dos breas de petróleo (BPP) y (BPT). Los datos demuestran la viabilidad del uso de estas breas en la fabricación de morteros con menores contenidos de cemento, permitiendo diseñar un nuevo material sostenible con el medio ambiente y que contribuya a reducir el impacto ambiental de los materiales de construcción, hecho que permite abrir una nueva vía de valorización de estos subproductos.; This article discusses experimental data on the flexural and compressive strength of Portland cement mortars containing additions or cement replacements consisting in petroleum or coal tar, by-products of the oil and coal industries. The materials studied were two coal (BACA and BACB) and two petroleum (BPP and BPT) tars. The results show that it is feasible to use such materials as a partial replacement for cement in mortar manufacture. This should lead to the design of a new sustainable product that will contribute to lowering the environmental impact of construction materials while at the same time opening up an avenue for the re-use of this type of industrial by-products.

Título: Effect of carbon fibres on the mechanical properties and corrosion levels of reinforced portland cement mortars Autor/es: Garcés Terradillos, Pedro; Fraile, J.; Vilaplana Ortego, Eduardo; Cazorla Amorós, Diego; García Alcocel, Eva María; García Andión, Luis Resumen: The changes in mechanical properties of portland cement mortars due to the addition of carbon fibres (CF) to the mix have been studied. Compression and flexural strengths have been determined in relation to the amount of fibres added to the mix, water/binder ratio, curing time and porosity. Additionally, the corrosion level of reinforcing steel bars embedded in portland cement mortars containing CF and silica fume (SF) have also been investigated and reinforcing steel corrosion rates have been determined. As a consequence of the large concentration of oxygen groups in CF surface, a good interaction between the CF and the water of the mortar paste is to be expected. A CF content of 0.5% of cement weight implies an optimum increase in flexural strength and an increase in embedded steel corrosion.
