The rolling-shutter boxes with inspection by the bottom, called Hyde, are characterized by having a structure in flame retardant expandable polystyrene of 25 kg/m3, covered externally with an anchoring network and mortar, sand, and cement admixed with clinging latex, to give maximum set to the application of plaster on the walls.
The tip of the hole is filled with high strength mortar to anchor firmly the prestressing tendon.
Concrete or brick and mortar walls require expansion anchors.
Since then, crews of stonemasons have been busily filling cracks with epoxy, relining stone interstices with more than 14,000 feet of mortar, and installing metal cradle anchors to reinforce the stone ribs sustaining the monument's pyramidion.
PIXE analyses allow the quantification of the amount of pigments anchored onto the hardened mortars, even if the observations by Scanning Electron Microscopy (SEM) remain necessary to study the near-surface microstructure, especially for the rough samples.
In this paper the authors investigate the influence of mortar joints on the efficiency of anchored CFRP reinforcements on brick masonry.
In the case of unreinforced masonry joints (mortar joints, such as those found in brick buildings), the anchoring between adjacent walls is especially important.
Always use lead anchors to hold the screws into place if you drill into the mortar, as screws set in mortar will work themselves loose over time.
The parameters examined in this study include: (a) the use of textile-based anchors as end-anchorage system of TRM U-jackets; (b) the number of TRM layers; (c) the textile properties (material, geometry); and (d) the strengthening system, namely textile-reinforced mortar (TRM) jacketing and fibre-reinforced polymer (FRP) jacketing for the case without anchors.
The amount of weight that the anchor can hold will be determined by the strength and condition of the wall itself (e.g., old brick and mortar walls that are in poor condition tend to be brittle and can crumble; this directly impacts how much weight an anchor can support).
