Rainwater penetration into building facades results in multiple issues, including material and structural degradation, reduced energy efficiency, and health-related concerns among occupants. Currently, the watertightness performance of building facades is assessed based on standardized tests, which simulate generic water supplies and pressure diffe...

The construction industry must meet current environmental requirements, mostly those pertaining to the reduction in construction and demolition waste and the consumption of raw materials. The use of recycled concrete aggregates can be part of the solution, but one question that arises is how many times recyclables can be recycled. This unknown invo...

A regulatory framework is required to ensure the correct design of Fibre-Reinforced Polymers (FRPs) increasingly being used as an externally-bonded strengthening system on concrete columns. Several design guidelines on the confinement of FRP concrete have been developed over the past few years worldwide, each proposing a different approach, resulti...

In the present study, the recycling of modified bitumen soundproofing membranes, known as automotive type membranes (ATR), was carried out. The ATR sheet waste was incorporated in the mixing stage of the asphalt mastic, which is part of the manufacturing process of new sheets. The selection of the best asphalt mastic formulation was carried out at...

Damage on historic heritage caused by salts related to bird droppings should be properly identified and located. The best combination of methodologies in order to identify the source of such type of salts consist of: mapping surface conductivity of walls, extracting salts using cellulose poultices and evaluating solutions geochemistry. In this case...

El deterioro ocasionado en el patrimonio histórico a consecuencia de las sales procedentes de deyecciones de palomas debe ser adecuadamente identificado y localizado. La realización de mapas de conductividad superficial en los paramentos, la extracción de sales mediante apósitos de celulosa y su análisis químico, y la posterior evaluación geoquímic...

The precast concrete industry produces a substantial quantity of waste due to quality non-conformances. Rather than deposit them in landfill, these products can be crushed, generating recycled aggregate, a by-product that may be reintroduced in the manufacturing process. But, what would happen if the recycled concrete pieces were rejected again? Is...

Reuse of cohesive soils in construction works is rare because of both unfavourable geotechnical characteristics and to the specific needs of placing conditions. This paper evaluates the improvement in compactness of a lutitic material (silty soil) present in large areas of the province of Zaragoza, Spain, by mixing with a sandy construction and dem...

The construction industry must adapt to new environmental requirements and becomes more sustainable. Recycling concrete waste to produce new concrete is one of the main ways of reducing the construction industry environmental impact. In the precast industry some of the concrete elements produced are rejected due to quality test failures. These prod...
