Recycled aggregates may make an important contribution toward decreasing the adverse consequences of the production and the dumping of construction and demolition waste (CDW) on the environment. The results of the experimental research work carried out at Lisbon’s Instituto Superior Técnico and Laboratório Nacional de Engenharia Civil are presented in this article. Normalized laboratory tests to assess the performance of standard mortars were used to demonstrate the technical feasibility of recycling the waste produced by the ceramics industry and from the demolition of red-clay bricks or tiles to produce mortars with less/no consumption of natural aggregates. Results are very promising up to a replacement ratio of sand with ceramic waste of at least 20%. The paper presents useful data for the ceramics industry, builders and mortar manufacturing companies in terms of minimizing the impact of CDW and using eco-efficient materials.

This paper aims at compiling the most relevant information concerning the use of cement-based mortars and concretes in the rehabilitation, retrofitting, and strengthening of hydraulic structures, namely concrete dams. The most important properties of cement-based mortars and concretes as repair materials are addressed, with a special focus on its compatibility with the concrete substrate. After a brief allusion to generic preparatory works, some of the most common practices are described. The main topics are mortar and concrete toppings, i.e., patches and overlays and thickening of the dam section. Among overlays, shotcrete and underwater works are addressed in detail. Littlerock, Oberems, and Storfinnforsen dam interventions are briefly described as successful rehabilitations involving the shotcrete method, whereas the Albbruck-Dogern dam intervention is given as an example of effective underwater repair works. As for dam section modifications, Kölnbrein, Olef, and Sasanagare dams are presented as conventional mass concrete placements within rehabilitation operations, while Les Toules, Gibraltar, Santa Cruz, and Littlerock dams are references for roller compacted concrete strengthening.
