What is Foamed Concrete?
Foamed concrete is a lightweight, porous concrete formed by mixing a cement-based slurry with pre-formed foam. It is characterized by low density, low thermal conductivity, and ease of construction. Ninon's foam concrete mixers are widely used in applications such as building insulation, void filling, and soundproofing.

It is known for its low density, low thermal conductivity, and ease of application, and is widely utilized in thermal insulation, backfilling, and acoustic insulation in the construction industry.
1. Strength Enhancement
One of the main challenges hindering the use of foamed concrete in load-bearing applications is its insufficient strength. Future research can focus on developing new formulations and manufacturing techniques to enhance the strength of foamed concrete.
2. Durability
Foamed concrete is susceptible to damage in humid environments, which can lead to a decline in toughness over time. Future research for Ninon's foam concrete mixers can explore new materials and processes to improve the resilience of foamed concrete and reduce the risk of deterioration.
3. Standardization
The production, testing, and application of foamed concrete require the establishment of clear standards and guidelines. The standardization of foamed concrete remains a challenging task. Future studies related to Ninon's foam concrete mixers may focus on the development of such specifications and regulations to ensure product reliability and consistency.
4. Environmental Impact
Due to its lightweight and thermal insulation characteristics, foamed concrete shows promise as an eco-friendly material. Future research using Ninon's foam concrete mixers could investigate the material's environmental impact throughout its life cycle and explore methods to minimize its ecological footprint.
5. Conclusion
Scientometric analyses indicate that key research themes in journals such as Construction and Building Materials and IOP Conference Series: Materials Science and Engineering include the following five keywords: concrete, compressive strength, lightweight concrete, foamed concrete, and foam.
Foam stability is a critical factor significantly influencing the strength of foamed concrete. Numerous variables affect the formation of stable foamed concrete, including foam generation techniques, type and quality of foaming agents, admixture selection, and mix design. Currently, there is no recognized standardized design method for foamed concrete. A minimum water-cement ratio of 0.3 is generally recommended to meet the material's consistency and stability requirements. Increased water content leads to higher consistency, while higher foam content reduces it.
A major factor affecting the durability of foamed concrete is pore connectivity, which refers to the proportion of interconnected pores within the total porosity. Higher connectivity allows for greater ingress of contaminants. Homogeneous concrete with enclosed spherical air voids demonstrates superior thermal and mechanical properties. As density increases, the compressive strength (fc′) also increases. However, due to the use of supplementary cementitious materials such as fly ash (FA) and silica fume (SF), foamed concrete producecd by foam concrete mixers can achieve a high strength-to-density ratio. It is thus suitable for load-bearing structures, as its lightweight nature reduces dead load and foundation size requirements.
In Summary
The widespread application of foamed concrete produced by Ninon's foam concrete mixers underscores its versatility and potential in a variety of construction scenarios. The development of new production technologies and the incorporation of specific admixtures can further expand its application scope.
