Foam concrete is a versatile building material with a simple production method that is relatively inexpensive compared to autoclave aerated concrete. [1] Foam concrete compounds utilising fly ash in the slurry mix is cheaper still, and has less environmental impact. Foam concrete is produced in a variety of densities from 200 kg/m 3 to 1,600 kg ...
Spray foam. Spray foam insulation extruding from a duct. Spray foam (expanding foam in the UK) is a chemical product created by a chemical reaction of two component parts, commonly referred to as side A and side B. [1] Side A contains very reactive chemicals known as isocyanate. Side B contains a polyol, which reacts with isocyanates to make ...
Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...
With a strike deadline looming, the group representing East and Gulf Coast ports is asking a federal agency to make the Longshoremen's union come to the bargaining table to negotiate a new contract.
Shotcrete, gunite (/ ˈɡʌnaɪt /), or sprayed concrete is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface. This construction technique was invented by Carl Akeley and first used in 1907. [1]: 7 The concrete is typically reinforced by conventional steel rods, steel mesh, or fibers.

By installing insulation, buildings use less energy for heating and cooling and occupants experience less thermal variability. Retrofitting buildings with further insulation is an important climate change mitigation tactic, [1][2] especially when buildings are heated by oil, natural gas, or coal-based electricity.
