— Lightweight concrete, also known as EPScrete (expanded polystyrene concrete), is a material widely used in the building of environmentally "green" homes. …
concrete is an incredibly useful material used to produce large volumes of relatively low strength void filling material; it can easily be pumped long distances and will fill most cavities. concrete is very fluid and flowing, it will "search" without requiring levelling or compaction, Moreover, concretes will flow through ...
— ASTM C796-93 gives a method to calculate the volume of required preformed to make the cement paste if the ratio W/C and the desired density are known [4]. Kearsley proposed a set of equations (density and volume) which is written in terms of the mixture composition, that allow the volume and cement content …
concrete is a highly fluid, lightweight cellular concrete fill material made by combining a cement paste (slurry or mortar) with a prepared that has been generated separately. The ratio of to slurry determines the density of concrete, which usually ranges from 300 to 1600 kg/m3. To further improve the qualities of ...
