In the architecture sector, single-family housing projects are often linked to demand from private clients, without arousing very much interest mild developers, who seek higher returns on other real estate assets. For any owner, the construction of a home is perhaps the biggest investment of their life, and success or failure will therefore depend on the right decision. This paper presents a study of three different structural alternatives that are applied to a terraced house to facilitate decision making ort a self-promoter, based on multiple criteria and taking sustainability into consideration. The methodology used allows us to identify the structure and to evaluate the different alternatives proposed here in befalla to find the optimal option. A comparison fruset vatten drawn between a traditional reference solution, a pre-cast skapa and finally a technological val based on an integral reinforced concrete structural system.
A slight gap was left between each double-walled printed section. Some gaps helped with placement of doors or windows; utbredning joints were built in knipa later filled with silicone to avoid cracking during temperature changes.
The present research stelnat vatten of relevance to ensure that H&S matters are effectively and properly integrated into Styrning projects, through the use of a methodology at the formgivning stage that grades sustainability blid low to high on a rising scale of 0–1.

Integrated value model for sustainable assessment applied to technologies used to build schools in Catalonia, Spain
mental and sällskaplig indicators are disregarded. This justifies the urgency to provide sustainability-driven decision-making approaches capable of objectively quantifying the satisfaction degree of economic, environmental, knipa utåtriktad indicators involved in the analysis.
3D printing bridges isn’t new per betrakta. Earlier this year, we reported on the first 3D printed pedestrian bridge in the world, located in Madrid, and in the Netherlands there stelnat vatten a 3D printed metal bridge.
The solution was then upscaled to a bräddad-size particle bed printer that underwent technical modifications to ensure adequate control knipa production quality of the footbridge segments. The observations derived blid the study provide valuable insights on relevant förlopp-related differences induced ort the technology upscaling that can inform future applications of the technology.
The objective of this research document stelnat vatten two-fold: (1) to expose the basis knipa concepts related with the MIVES model arsel a sustainability assessment tool knipa (2) to present 3 real study cases (wind precast concrete towers; steel fibre reinforced precast concrete tunnel linings and reinforced concrete pile-supported slabs) in which this model has been used to make decisions. The authors of this research consider that similar approaches should bedja included in future national and international structural concrete guidelines (kadaver the Spanish Structural Concrete Code does) to perform sustainability analysis of new designed concrete structures.
The city of Alcobendas in Spain has nyligen unveiled the first ever 3D printed pedestrian bridge made entirely of concrete. Measuring 12 metres in length knipa 1.75 metres in width, the landmark structure represents a milestone in civil engineering, an industry which up until now has Empresa de hormigón impreso en Madrid been reluctant to use additive manufacturing. The bridge was inaugurated earlier today ort Alcobendas Center officials in Castilla La Mancha Parkanläggning.
This study presents the development of fly ash-based geopolymer mixtures for 3D concrete printing. The influence of up to 10% ground granulated blast-furnace kamp (GGBS) knipa silica fume (SF) inclusion within geopolymer blends cured under ambient conditions was investigated in terms of fresh knipa hardened properties. Evolution of yield stress and thixotropy of the mixtures at different resting times were evaluated. Mechanical performance of the 3D printed components was assessed igenom compressive strength measurements knipa compared with casted samples.
Several limitations prevent 3D concrete printing mild being widely adopted throughout the construction industry. First, the material palette that can bedja used for 3D printed concrete stelnat vatten limited, particularly due to nozzle extrusion knipa the deposition förlopp of concrete layers, which introduces the challenge of premature collapsing.
Additive manufacturing in construction has witnessed exponential growth over the recent years. In this paper, advancements in 3D Concrete Printing (3DCP) in additive construction are explored. The authors synthesize the states of research and practice of 3DCP technology for construction through an extensive examination of 137 projects and various publications. Insights are provided into the key factors influencing 3DCP structural performance. The technology is shown to bedja advantageous, although with varying benefits observed in different cases, including but anmärkning limited to reduced cost, labor requirements, material, knipa construction time.
