Cellular Lightweight Concrete Slideshare

Lightweight concrete is a special concrete which weighs lighter than conventional concrete.

When cellular concrete hardens it has an oven dry density of 50 lb ft3 8 t m3 or less. These clc blocks are competitive with red clay bricks in pricing and offer significant savings cellular lightweight concrete clc. The foam looks like shaving cream and is varied in quantity to control the unit weight of the cellular concrete. Lightweight cellular concrete lcc contains type i ii v portland cement water and a preformed foam.

These air voids are established in the material via the introduction of either a protein based or synthetic based foaming. The purpose of the foam is to supply a mechanism by which a relatively high proportion of stable air voids can be induced into the mixture and produce a cellular or porous solid upon curing of the mixture. Clc is an air cured lightweight concrete with fly ash as a major ingredient that can be produced at large project sites just like traditional concrete utilising equipment and moulds normally used for traditional concreting. Cellular concrete is a mixture of cement water and preformed foam.

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. In cellular lightweight concrete the density can be controlled by the introduction of gas or foam by foam generator. By replacing the conventional aggregates by cellular porous aggregates light weight agg. Density of this concrete is considerably low 300kg m3 to 1850kg m3 when compared to normal concrete.

Cellular light weight concrete clc is a light weight concrete that is produced by mixing cement and flyash slurry with pre formed foam. Cellular concrete may go by other names including foam cement foamed concrete or lightweight flowable fill. By omitting the sand from the concrete no fines concrete. Lcc lightweight cellular concrete is an excellent product works well for the application.

Clc blocks cellular light weight concrete blocks are made of cellular light weight concrete clc or foam concrete. It may also be defined as. By incorporating the air or gas bubbles in concrete aerated concrete. Concrete which uses lightweight aggregates may consist of lightweight aggregates are used in ordinary concrete of coarse aggregate and sand clay.
