Alternative to Concrete – Lightweight Polystyrene Concrete Blocks


Polystyrene concrete blocks generally are made from a mix of cement silica aggregate, recycled polystyrene granules and modifying agents like setting accelerators, according to Interesting Engineering, though each manufacturer has a slightly different formulation. The blocks are lighter than traditional concrete and, as such, can reduce required labor for constructing masonry walls while increasing the speed at which they’re built. Uses include as an insulation system for new and existing buildings or as a construction material. Their composition uses fly ash from thermal power stations, which is a by-product that electrostatic precipitators captures, and silica, which contributes to the product’s thermal properties. Concrete is getting more attention as researchers look to improve it and use the material in new ways. In October, MIT researchers started exploring concrete at its atomic level to improve its durability and environmental impact in full-scale use. Researchers will develop a computer model that will be able to gauge concrete’s durability when other additives, especially locally sourced ones, are used…Read More > >
