Fly Ash Based Cellular Lightweight Concrete. It is a version of lightweight concrete that is produced like normal concrete under ambient conditions. It is produced by initially making a slurry of Cement +Sand + Fly Ash (constituting 26% 34 % content) + water.
Cellular lightweight concrete is slurry of cement, sand, water, fly ash and preformed stable generated by generating machine. 53 and 43 grade Ordinary Portland Cement is used. In this mix, one part of cementious material
#0183;#32;The conformation of cellular concrete type materials based on fly ash and solgel solutions with nanosilica was achieved. The heat treatment of the fly ash materials achieves a porous structure and it is no longer soluble in water. The cenospheres were dissolved in the process and conform the new porous vitreous structure.
Cellular Lightweight Concrete Using Fly Ash. Abstract. Cellular Light weight Concrete (CLWC) is not a new invention in concrete world. It has been known since ancient times. It was made using natural aggregates of volcanic origin such as pumice, scoria, etc. The Greeks and the Romans used pumice in building construction.
The use of light weight concrete gives an outlet for industrial wastes such as fly ash, clinkers, slag etc, which create problem for disposal. It offers great fire resistance. Light weight concrete gives overall economy. Disadvantages of Lightweight Concrete : Lightweight concrete is generally very sensitive with water content in the mixture.

Cellular concrete, occasionally referred to as concrete, is a lightweight construction material consisting of Portland cement, water, ing agent and compressed air. The is formulated to provide stability, increase in volume of mortar and prevent draining of water. 2.

Fortunately, fly ash can be used as a beneficial additive in some applications particularly in concrete products, where it is used as a lightweight aggregate (LWA).The benefits of using fly ash as a lightweight aggregate in concrete products are so great that the concrete industry has come to rely on this powergenerated byproduct.
Cement Lightweight ed concrete can be gaseous or ed B. Water concrete that uses specially prepared chemicals; it can be a C. FlyAsh nofines concrete that uses ordinary gravel or crushed stone, D. ing a normalweight aggregate concrete with an excessive amount of entrained air, or a concrete that is made from Size of blocks is as following: lightweight aggregates.
Fly Ash Cellular Lightweight Concrete Properties and Uses . Cellular lightweight concrete is one of the latest emerging technology in making the concrete. The CLC has many benefits over normal conventional concrete. As we know the Fly Ash is the waste product of thermal power plant which cannot be easily disposed of. This solves the problem of disposal of fly ash and also reduces the cost of construction.
Fly Ash based Cellular Lightweight Concrete Properties and
Abstract: Cellular lightweight concrete (CLC) Fly ash (FA) is a byproduct from the combustion of pulverized coal in power plants. Based on the recorded production and production estimates, the worldwide production of NZ is approximately 34 million tons per year[1].
To improve the comprehension and utilization of lightweight cellular concrete mixed with fly ash (LCCF) and ensure project quality in subgrade construction engineering, the construction techniques and quality control measures of LCCF are studied in this paper. The corresponding research contents, based on a specific project case located in Guangdong Province, are as follows.

Cellular concrete is concrete that has been manufactured to contain lots of closed air pockets. Lightweight and fairly energy efficient, it is produced by adding a ing agent to concrete. Fly ash (residue left from burning coal, which is collected on an electrostatic precipitator or in a baghouse) is also introduced to improve the quality and durability of the concrete mix.
Fly ash based cellular lightweight concrete properties and therefore fly ash based clc is considered as environment friendly sustainable material produced with least energy demand the density is considerably reduced by using fly ash based cellular lightweight concrete than normal concrete and at the same time the strength is .
