Foam Concrete (CLC) vs. Aerated Concrete (ALC/NAAC): Production Differences Explained
- 2 months ago
Aerated concrete (ALC/NAAC) and foam concrete (CLC) differ mainly in their production methods.
Aerated Concrete (ALC/NAAC):
Aerated concrete is made by blending water, cement and fly ash in a high-speed mixer, with ALUMINIUM powder added lastly as a foaming agent. Once poured into a mold, it expands in 15-30 minutes, forming a consistent structure with small pores.
Formed concrete cake is cut in to pieces with wire cutting machines resulting six surface cuts with higher dimensional accuracy.
Foam Concrete (CLC):
Foam concrete, however, combines water, cement, and fly ash first, and then mixes in FOAM generated by a special foam generator machine. The mixture is stirred slowly and carefully to maintain the foam bubbles. Yet, the foaming agent in foam concrete can inhibit the cement setting process, requiring more cement and an extended setting duration.
This foamed concrete slurry is poured into Molds with individual compartments for each block. These Molds are greased for easy removal. Due to this, surface of block becomes smooth and oily. Which may result in weaker joints.
In Summary:
CLC-Foam concrete is well-suited for tasks like laying floors and onsite casting, mainly used for insulation and where strength is not crucial.
Nevertheless, due to higher production expenses and narrower profit margins, foam concrete blocks find it challenging to rival aerated concrete blocks in other brick wall construction applications.
ALC is better over CLC considering-
Lower density with higher strength
Accurate dimensions
Better esthétiques
Lower production cost
