Epoxy adhesives can be developed to suit almost any application. They can be used as adhesives for wood, metal, glass, stone, and some plastics. They can be made flexible or rigid, transparent or opaque/colored, fast setting or slow setting. Epoxy adhesives are better in heat and chemical resistance than other common adhesives.
The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history. The field has undergone a continuous evolution, driven by human dependence on water, meteorological conditions and internal ...
Originally, concrete was used as a matrix, which means that older pieces will be structurally unsound and require renovation. Today, modern technology has created appropriate solutions: An epoxy resin was created with the same expansion rate as the glass. This resin is now used as a matrix instead of concrete. This has solved all structural ...
Prince Rupert's drop. Prince Rupert's drops (also known as Dutch tears or Batavian tears) [ 1][ 2] are toughened glass beads created by dripping molten glass into cold water, which causes it to solidify into a tadpole -shaped droplet with a long, thin tail. These droplets are characterized internally by very high residual stresses, which give ...
The history of glass-making dates back to at least 3,600 years ago in Mesopotamia. However, most writers claim that they may have been producing copies of glass objects from Egypt. [ 1] Other archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or Egypt. [ 2]
To make glass, the glassmaker starts with the batch, melts it together, forms the glass product, and gradually cools it. The batch is dominated by sand, which contains silica. Smaller quantities of other ingredients, such as soda and limestone, are added to the batch. Additional ingredients may be added to color the glass. For example, an oxide ...
Asphalt concrete (commonly called asphalt, [ 1] blacktop, or pavement in North America, and tarmac or bitumen macadam in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. [ 2] Asphalt mixtures have been used in pavement construction ...
