The NaOH solution was prepared by dilute NaOH pellets with distilled water.
Cellular Concrete—What is it? Cellular Concrete is a lightweight, very strong, cement product used as a soil/fill replacement. Also referred to as: Foam Cement Aerated concrete Lightweight cellular concrete (LCC) Low Density Cellular Concrete (LDCC) Low Density Controlled Low Strength Material (LD—CLSM) Lightweight Insulating Concrete Cellular Concrete is produced by substituting some or
Fly ash is a byproduct from coal-fired power plants that is frequently used as an admixture in concrete to replace a portion of the Portland cement. Using fly ash in concrete is environmentally beneficial because it reduces the Portland cement (a major contributor of CO2) required in concrete.
Cellular lightweight concrete is slurry of cement, sand, water, fly ash and preformed stable foam generated by foam generating machine. 53 and 43 grade Ordinary Portland Cement is used. In this mix, one part of cementious material (i.e. cement and fly ash) and 3 part of sand is used.
The fly ash is used in the manufacturing of light-weight concrete. fly ash is a key ingredient and at the same time, the disposal problem is also solved. Foam In the raw material the foam is used and in the making of cellular concrete is Genfil and its organic substance.
Cellular lightweight concrete: Foam concrete is a mixture of cement, fly ash, sand, water and foaming agent. When the When the foaming agent is diluted with water and air, further it
concrete, is defined as cement based slurry. It is a light weight, water resistant, fire- proof, sound proof and environment friendly. The main feature of this block is light in weight. Cellular Lightweight Concrete blocks are made of fly ash, cement, and foaming agent. These can be extensively used in all building constructional activities
Concretewhich separates fly ash into three types based on the calcium content of the fly ash as shown in Table 3. The calcium content of the fly ash is perhaps the best indicator of how the fly ash will behave in concrete (Thomas 1999), although other compounds such as the alkalis (Na 2 O and K 2 O), carbon (usually measured as LOI), and

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.
