In contrast to ordinary concrete, CLC has a honeycombed structure generated by blending a foaming agent or prefoamed composite with the cement slurry. The voids created through air entrainment contributes unique properties that separate CLC from traditional concrete.
The idea behind cellular concrete is not new; it has been in use and progressed since the early 1900s. With advancements in technology and new types of instrumentation used today, modern techniques have enhanced its purpose and made it more versatile for general and special construction applications.
Materials and Methods of CLC Foamed Concrete
CLC foamed concrete is produced from a very simple and effective raw mixture of materials:
- Cement – Most of the time, the binder is Ordinary Portland Cement (OPC). It is perfect with regards to the production of foamed concrete because of its strength and durability.
2. Foaming Agent – The most essential innovation of this technology, the foaming agent develops the signature cellular structure or air bubbles. This agent can be either synthetic or natural, and it produces stable bubbles which stay during curing.
3. Water – Water is the necessary component to hydrate cement and produce the slurry mixture.
4. Fine Aggregates (Optional) — Sand or other fine aggregates are sometimes used for reinforced applications.
5. Fly Ash (Optional) – Fly ash is a byproduct from the combustion of coal and is primarily used as a partial replacement for cement to enhance workability and reduce the cost of the material.
The process to create CLC is simple and energy efficient:
- Mixing the Slurry
These include the primary ingredients (cement and water) as well as additional materials (fly ash or fine aggregates) which may be used and these materials are combined into a heterogeneous slurry. [It] ensures that the adhesive properties of the mix are the best.
2. Foam Generation
The foaming agent is mixed with water and aerated (usually through use of special foam-generating equipment). This produces a stable foam which makes up to 80% of the total volume in low-density applications.
3. Importance of Foam in Cement Slurry
Foam is generated from its ingredients and injected into the cement slurry while being mixed to ensure that the foam are distributed homogeneously. This imparts a lightweight and cellular nature to the end mixture.
4. Pouring and Curing
The prepared CLC mixture is filled in molds or directly utilized in construction applications. This is then left to cure under regular atmospheric conditions without additional curing methods.
Hence the final output is a lightweight, strong (with adjustable density (400 kg/m³ to 1,800 kg/m³) flexible concrete that can find applications in various branches of construction.
