Introduction: Health centers as one of the main urban services, and one of the key factors in assessing the feasibility of sustainable development in cities have a high sensitivity to location and choice of accommodation. Case Report: Shirvan is the largest city after the capital of the province in North Khorasan of Iran. On the southern edge of the city of Shirvan, there is a seasonal river between the city and Ayatollah Hashemi Rafsanjani Hospital. The need to build a solid bridge is essential for safe access to the hospital, which, unfortunately, has not been achieved. The constructed roundabout passes approximately one meter from the river floor. In the spring of 2019, there was heavy rainfall in most parts of the country, and the area was not poor. The rains blocked access to Ayatollah Hashemi Rafsanjani Hospital as water flowed into the seasonal river. Conclusion: A hospital that should help itself to a crisis was itself a cause of the crisis in a short time.

Zusammenfassung Verkehrssteigerungen erhöhen die Anforderungen an den Brückenbestand. In einem vom Bundesministerium für Bildung und Forschung (BMBF) geförderten Verbundprojekt wurde eine dünne Ergänzungsschicht aus Textilbeton – Smart-Deck – für Brückenfahrbahnplatten mit drei Eigenschaften entwickelt: Feuchtemonitoring, präventiver kathodischen Korrosionsschutz und Erhöhung der Tragfähigkeit. Am Institut für Massivbau der RWTH Aachen (IMB) wurde die Verstärkungswirkung in Hinblick auf die Biege- und Querkrafttragfähigkeit untersucht. Nach einigen Laborversuchen zur Findung geeigneter Materialkombinationen und gezielten Untersuchung der oben genannten Funktionen der carbonbewehrten Zusatzschicht wurde ein erster Demonstrator realisiert, an dem die baustellengerechte Herstellung von Smart-Deck und weiterhin die nach realitätsnaher Herstellung erreichbaren Funktionen überprüft werden konnten. Im nachfolgenden Beitrag werden die experimentellen Untersuchungen vorgestellt, über die der Beitrag von Smart-Deck zur Tragfähigkeit der Demonstratorplatte ermittelt werden konnte. Dazu wurden Streifen mit unterschiedlichem Biegezugbewehrungsgrad entnommen und am IMB mit variierenden Laststellungen getestet.

Densified biomass pellets named as H/S-BPs were prepared from waste wood sawdust (S) in the presence of water hyacinth fiber (H) as solid bridge under room temperature and 6 MPa lower than in the previous study. Mechanical properties including relaxed density (ρr), resiliency (R), abrasion resistance (AR) and impact resistance index (IRI) were evaluated. Results showed that adding H greatly reduced negative effect of resiliency on the mechanical properties of H/S-BPs during storage. For example, H/S-BPs compressed at 6 MPa in an H/S mass ratio of 1 to 3 presented lower resiliency of 10% and higher relaxed density of 1.04 kg dm-3 than pellets without H fiber. This is due to the intertwining action of H fiber, what fabricates solid bridge, replacing the bonding creating by applying high pressure to resist the disruptive force caused by elastic recovery. Thus, compression of waste H and S in a mass ratio of 1 to 3 at room temperature under 6 MPa is a cost-effective process to produce densified sustainable bio-fuel pellet as well as dispose waste S and H, combining the economical and environmental benefits.
