Electric Arc Furnace (EAF) slag can be reused as aggregate in Portland cement concrete mixes. The addition of EAFS and other waste co-products (fly ash, blast furnace slag) will modify the binding properties will, importantly, enhance global sustainability such concretes. These mix designs offer acceptable pumpability self-compaction fresh state reinforced with fibers. In this study, eight different mixes are designed within range medium-strength concretes (30–50 MPa) characterized both...

Abstract Masonry arches are an important part of built heritage that must be preserved. Research and advanced studies historical masonry structures have progressed slowly in comparison to on made other materials (e.g., concrete, steel), resulting a lack knowledge experience this field. This research evaluates the effectiveness basalt textile-reinforced mortar (BTRM) as compatible strengthening composite material for stone arches, providing researchers with further quantitative data. To do...

Cultural and Natural Heritage (CNH), a legacy bequeathed to present future generations, casts light on the humanity of past generations. However, increase intensity natural climate-change-related hazards threaten conservation such heritage. The aim this research is develop multi-criteria prioritization methodology in support intervention decisions, enhance resilience CNH through sustainable development. application two methods, Integrated Value Model for Sustainability Assessment Analytical...

Reinforced concrete structures came to Spain in the late-19th century, somewhat after development of this new construction material elsewhere Europe. Their introduction was pioneered industrialized areas, especially Northern Spain, under systems first patented other European countries. Local constructors built patents with little or no explanations account for calculation, design, and technique. Some these buildings from recent past are now listed buildings. This study centres on three...

The increasing energy consumption levels of buildings within Europe call for controlled and improvements to savings efficiency effective regulations. However, many aging energy-inefficient require energetic retrofitting that can employ various façades solutions insulation materials. selection the most sustainable options in each situation therefore requires a decision-making methodology be used prioritize available retrofit based on economic, functional, environmental social criteria. In...

Facing a scarcity of land for urban development and demand public services, the Municipal Council Bilbao recognizes need to make good use its built heritage upgrade it, while maintaining cultural functional features. A example is case Ribera Market, largest covered market in Europe. Deterioration building pressure improved services has led proposals rehabilitation. To do so, constructive condition must first all be assessed and, then, most appropriate compatible intervention technique...

Laser texturing is a process used to remove material selectively. Metallic parts were processed in order create surface texture that enables metal-polymer joining. This kind of dissimilar joining carried out combining pressure fixture and heating using direct diode laser source. In reach good result, it critical the with correct parameters generate features maximizes contact between materials enough soften polymer but without melting degrading material, so, temperature control system...

An alternative experimental method for predicting the diagonal shear cracking resistance of steel-reinforced concrete beams is developed in this paper. Conventional extensometric strain-gauge rosettes are placed on lateral surfaces a set four beams. As propagates through beams, load–strain curves flatten out at plateau and mechanical property under consideration may be determined. The applied to cast from pumpable self-compacting mixes with cement types I IV containing electric arc furnace...

The special properties of 3 D-Printed Concrete in terms rheology, deposition technology, and dosage substantially modify its mechanical after hardening. In this paper, comparisons are drawn between different concrete strength development models specified the main Building-Codes Standards experimental data from tests on various thixotropic mortar mixes suitable for 3DPC. aim was to develop an empirical procedure improve current models, so that their results could predict 3DPC bulk materials...
