In 1996, The Wall Street Journal published a profile of Billings that also described fire-resistance testing of Geobond by Underwriters Laboratories, the Kansas City Fire Department, and a government lab at Edwards Air Force Base. [1] Geobond research was initially funded by Billings.; [9] it was patented in 1997. [10]
Polypropylene is discovered by Giulio Natta with production starting in 1957 [1] 1954: Expanded polystyrene, used for building insulation, packaging, and cups, is invented by Dow Chemical. [1] 1957: The Italian firm Montecatini begins large-scale commercial production of isotactic polypropylene. 1960s
Cement powder in a bag, ready to be mixed with aggregates and water. [1] Cement block construction examples from the Multiplex Manufacturing Company of Toledo, Ohio, in 1905. A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together.
In 2001, in an attempt to commercialize the technology they replaced the binding materials with a health-neutral polymer additive. Laboratory tests were completed on fire resistance and compressive tests. This light polystyrene concrete turned out to be structurally stable, light weight (from 100 to 300 kg/m 3) and 100% fire retardant. A ...
The first plastic made from synthetic components, it was developed by Leo Baekeland in Yonkers, New York, in 1907, and patented on December 7, 1909. [ 3 ] Bakelite was one of the first plastic-like materials to be introduced into the modern world and was popular because it could be moulded and then hardened into any shape.
The expanded graphite can be used to make graphite foil or used directly as a "hot top" compound to insulate molten metal in a ladle or red-hot steel ingots and decrease heat loss, or as firestops fitted around a fire door or in sheet metal collars surrounding plastic pipe (during a fire, the graphite expands and chars to resist fire ...
Engineers created a breakthrough cement that's 17 times stronger, leading to safer and more durable buildings. And they used an astonishing secret weapon.
Each ton of recycled plastic bags saves the energy equivalent of 11 barrels of oil, although most bags are produced from natural-gas-derived stock. [40] In light of a 2002 Australian study showing that more than 60% of bags are reused as bin liners and for other purposes, [ 41 ] the 7% recycling rate accounts for 17.5% of the plastic bags ...
