Prefabricated Elements Case Study

Robotized spraying of prefabricated panels

A robotized manufacturing cell of pre-fabricated GRC (Glass Reinforced Cement) panels for construction industry has been developed by DISAM for the Spanish construction company Dragados, S.A.The main contribution of the developed system is the automatic program~ ming and control of the whole plan. The architect's 3D-drawing of the building facade done on a CAD system serves as input. From the C...

The influence of ultrasound on removal of prefabricated metal post cemented with different resin cements

BACKGROUND Ultrasonic vibrations are used to remove a cemented post from a root canal requiring endodontic retreatment. Various results have been reported from the studies that evaluated the effect of ultrasonic instruments in removing the posts cemented with resin cements. The aim of this study was to evaluate the effect of ultrasonic energy on the retention of prefabricated metal post cemente...

Vapor-deposited amorphous metamaterials as visible near-perfect absorbers with random non-prefabricated metal nanoparticles

Spatial order or periodicity is usually required and constructed with tens of nanometers in the feature size, which makes it difficult to process the near-perfect metamaterial absorbers (PMAs) working in the visible range in large-area and mass-production scale. Although many established technologies and theoretical modeling methods used for order-based metamaterials, aperiodic or disordered st...

Mechanical properties of roots combined with prefabricated fiber post.

This study examined the mechanical properties of roots combined with prefabricated fiber post. Three types of specimens were evaluated: (1) prefabricated fiber post alone (FP); (2) core composite resin with FP (CFP); and (3) root with CFP (RCFP). The volume fractions of the prefabricated fiber post in the core composite resin (FP/CFP ratio) were set to 0, 0.16, 0.22, 0.28, and 0.48. Bending tes...
