Sustainability is a criterion defined since the 1980s, essential in all areas of activity, without which development cannot be acheived. Thermal insulation mattresses produced using sheep wool, successfully meet the conditions imposed by this criterion. This type of building material ensures the responsible use of non-renewable natural resources, the possibility of reuse and recycling of materials, contributes to environmental protection and pollution reduction, energy saving and provides a hygienic and healthy li...

In Romania, most of the construction and demolition wastes are stored together with other categories of waste or industrial by-products. Landfilling takes large areas of valuable land, but also causes air, water, and soil pollution, increasing the importance of any valorization or recycling technology for these types of materials. The European strategy regarding recycling concerns prevention, reuse and recycling of waste. The main materials that can be recovered from construction and demolition waste are: excavate...

Self-compacting fibre reinforced concrete summarizes both the advantages of selfcompacting concrete: reducing environmental noise pollution, faster construction time, improved quality of concrete surfaces etc., as well as the fibres benefits: better mechanical performance, ductile failure and so on. Self-compacting fibre reinforced concrete is not currently used in Romania especially due to the lack of normative research respectively the national regulations in this particular field. One of the national research p...

Development of Fibre Engineered Cementitious Materials with Self-Healing Capacity (SH-FECM) was an important goal of the recent research programmes conducted in NIRD пїЅURBAN-INCERCпїЅ Cluj-Napoca Branch. Several theoretical and experimental studies were performed in order to improve the composites, considering both, fresh and hardened state properties and also the performance as filling material of the narrow spaces at the beam to column interface within the Hybrid spatial joint model [1]. Present studies are foc...

The benefit of recycling industrial by-products in the construction industry led to growing interest in exploring and potentially exploiting these by-products, in the context of sustainable development, and in creating new materials. Fly ash is a type of byproduct waste, having enjoyed considerable attention, especially from the perspective of creating and perfecting fly ash based geopolymer concrete. In Romania, over 80% of industrial waste is deposited, this being the most widely used method of waste disposal. T...
