Foam concrete wiki
WebFoam 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 ... WebCrystals of platey strätlingite grow in the cementitious matrix of the material including the interfacial zones where cracks would tend to develop. This ongoing crystal formation holds together the mortar and the coarse aggregate, countering crack formation and resulting in a material that has lasted for 1,900 years. [5] [6]
