The management of end-of-life wind-turbine blades in the coming years will be necessary, as a clear solution for their recycling is yet to found due complex composition. suitability mechanical therefore evaluated this paper, obtaining Raw-Crushed Wind-Turbine Blade (RCWTB) subsequent incorporation high amounts up 10% vol. concrete, replacing aggregates achieve Fiber-Reinforced Concrete (FRC). Compressive strength levels 40 MPa were at all times reached, although with steadily decreasing...

The large number of wind farms that will have to be dismantled in coming years is prompting a search for reliable wind-turbine-blade recycling methods, but there not yet broad consensus on the most appropriate. Jointly crushing all blade components produces material referred as Raw-Crushed Wind-Turbine Blade (RCWTB), formed by fibers from Glass Fiber-Reinforced Polymer (GFRP) composite, and spherical balsa-wood polyurethane particles. incorporation this inexpensive easy-to-produce concrete...

End-of-life wind-turbine blades undergo non-selective crushing to produce Raw-Crushed Wind-Turbine Blade (RCWTB), which can be recycled as a raw material in concrete. RCWTB contains fibers from glass fiber-reinforced polymer that add ductility and load-bearing capacity Concrete mixes with percentage additions of between 0.0 % 6.0 by volume are produced analyze their compressive stress–strain performance, deflection under bending forces, deformability indirect-tensile stresses. Higher...

Raw-crushed wind-turbine blade (RCWTB), a waste from the recycling of blades, is used as raw material in concrete this research. It contains not only fiberglass-composite fibers that bridge cementitious matrix but also polyurethane and balsa-wood particles. Therefore, containing RCWTB can be notably affected by moisture temperature fluctuations exposure to high temperatures. In research, performance five mixes with 0.0%, 1.5%, 3.0%, 4.5%, 6.0% RCWTB, respectively, studied under moist/dry,...

Wind energy has been making its way into renewable energies until today, experiencing a continuous growth worlwide that leads to the urgent task of reflecting on and solving issue recycling wind turbine blades. Their complex composition causes currently there is no widely acepted solution for it. This study evaluates incorporation waste from crushing blades, which contains fibers, self-compacting concrete, can be used producing any construction element. Therefore, five concrete mixes were...

Analyzing and validating the behavior of sustainable concrete mixes under near-realistic conditions is essential to advance their use. In this research, full-scale high-workability concretes, 0.5 m3 in volume, containing maximum amounts raw materials response cyclic wet-dry tests are studied. The mixtures contained Electric Arc Furnace Slag (EAFS) Recycled Concrete Aggregate (RCA) as aggregates, Ladle (LFS) Ground Granulated Blast-furnace (GGBS) binders. Each mixture underwent 30 cycles with...

Introduction Engineering students should develop critical-thinking skills and insist on appropriate performance levels both from themselves their colleagues during training. In doing so, they will adopt critical attitudes toward own others’ work. This help them to successfully perform future professional work with the highest standards. Methods this research, peer- self-assessments of in-class presentations through a survey-based program were used analyze development among engineering...

A research experience on the construction of a pilot road section with porous asphalt mixture incorporating Ladle Furnace Slag (LFS) as fine aggregate in its composition is reported. The consisted overlaying this existing bituminous pavement and was intended to simulate real application sustainable material. Along paving, quality control conducted ensure that complied requirements current regulations for use. This included durability-performance study. Thus, water-sensitivity,...

Some of the first-installed wind turbines will have to be replaced soon, as they are approaching end their life span. These wind-turbine blades must recycled, so suitability added into concrete mixes fibers is studied. Thus, a less-polluting fiber-reinforced can achieved, maintaining its mechanical behavior. To recycle numerous at an adequate rate, large amounts waste need concrete. This study aims find out adding high this material (0% vol., 5% and 10% vol.). Testing yielded slight decrease...

Wind-turbine blades pose significant disposal challenges in the wind-energy sector due to increasing demand for wind farms. Therefore, this study researched revaluation of Raw-Crushed Wind-Turbine Blade (RCWTB), obtained through a non-selective blade crushing process, as partial substitute aggregates Self-Compacting Concrete (SCC). The aim was determine most adequate water/cement (w/c) ratio and amount superplasticizing admixtures required achieve flowability 7-day compressive strength SCC...
