Until the mid-1990s, foam concrete was regarded as weak and non-durable with high shrinkage characteristics. [1] This is due to the unstable foam bubbles resulted in foam concrete having properties unsuitable for producing very low density (Less than 300 kg/m 3 dry density) as well as load bearing structural applications. It is therefore ...
An interlocking system is designed so that it is impossible to display a signal to proceed unless the route to be used is proven safe. Interlocking is a safety measure designed to prevent signals and points/switches from being changed in an improper sequence. For example, interlocking would prevent a signal from being changed to indicate a ...
The first form of interlocking security is more mechanical. For example, if an individual is entering a building, there may be two sets of doors to enter from. As the individual enters the first door, that door will close before they enter through the second door. This type of interlocking security can prevent piggybacking or tailgating. The ...
In order to accomplish small gas cell formation in man-made thermal insulation, glass and polymer materials can be used to trap air in a foam-like structure. This principle is used industrially in building and piping insulation such as , cellulose, rock wool, polystyrene foam (styrofoam), urethane foam, vermiculite, perlite, and cork. Trapping ...
Coloured designs in textiles can be created by weaving together fibres of different colours (tartan or Uzbek Ikat), adding coloured stitches to finished fabric , creating patterns by resist dyeing methods, tying off areas of cloth and dyeing the rest , drawing wax designs on cloth and dyeing in between them , or using various printing processes ...
Interlocking spurs at Ashes Hollow, tributary to the River Severn Interlocking spurs looking up Oxendale Beck, tributary to the River Brathay in Lake District, Cumbria. An interlocking spur, also known as an overlapping spur, is one of any number of projecting ridges that extend alternately from the opposite sides of the wall of a young, V-shaped valley down which a river with a winding course ...
