lightweight concrete - what is lightweight concrete and,the light-weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less. the lightweight aggregates used are usually expanded shale, clay, or slate materials that have been fired in a rotary kiln to give them a porous structure, similar to volcanic rock..high-strength structural lightweight concrete,cellular concrete cellular concrete is a cementitious paste of neat cement or cement and fine sand with a multitude of micro/macroscopic discrete air cells uniformly distributed throughout the mixture to create a lightweight concrete. it is commonly manufactured by two different methods. method a, consists of mixing a pre-formed.cellular lightweight concrete (clc) blocks - advantages,clc blocks (cellular light weight concrete blocks) are made of cellular light weight concrete (clc) or foam concrete. cellular light weight concrete (clc) is a light weight concrete that is produced by mixing cement and flyash slurry with pre-formed foam. these clc blocks are competitive with red clay bricks in pricing and offer significant savings cellular lightweight concrete (clc.cellular lightweight concrete materials, applications and,density of cellular lightweight concrete the variable density is described in terms of kg per m³. the density of regular concrete is normally measured at 2400 kg/m³ whereas the density of the foamed concrete ranges from 400 kg/m 3 to 1,800 kg/m 3 the density of cellular lightweight concrete can be effectively determined by introducing foam formed utilizing a foam-generator..

foamed concrete, also called cellular light weight concrete is produced by the mixing of portland cement, sand including or alone fly ash, water and preformed stable foam. the foam is produced with the help of a foam generator by using foaming agent. the air content is
cellular concrete may go by other names including foam cement, foamed concrete, or lightweight flowable fill. although there are a number of lightweight cementitious materials, the key differentiating factor between cellular concrete and other lightweight cementitious materials is the use of externally generated foam to reduce the density.

gypcrete vs lightweight concrete. this is for a radiant floor overpour. the gypcrete sights all point out the flaws of concrete, but it seems to me that concrete has the distinct advantage of being mold resistant. this would be an 1 1/2″ slab & if using concrete, i would add fibermesh & an isolation membrane between the crete & the subfloor.
