फोम कंक्रीट को लाभ र हानि

फोम कंक्रीट एक विशिष्ट अकार्बनिक भित्ता थर्मल इन्सुलेशन सामग्री हो. यो समतल छत निर्माण मा प्रयोग गरिन्छ, चिसो भण्डारण, रिटेनिङ र एबुटमेन्ट पर्खालहरू, as non-load bearing or load bearing walls in RCC/Steel framed buildings, infill to arch bridges, in tunnels, subways and wells.

Advantages of foam concrete include its light weight, good environmental protection performance, excellent thermal insulation properties, high scope for industrialisation, and convenient construction [6,7]. अर्कोतर्फ, it has some disadvantages, including its poor strength and dry bulk density.

Lack of rigidity

A key component that affects the performance of foam concrete is the foaming agent and the foam stabiliser. These substances influence the air content, fluidity, and volume stability of the fresh slurry and eventually determine the dry bulk density and strength of the hardened body.

Excessive fly ash can cause the development of bubbles, which may lead to segregation. This can also reduce the complete volume and increase the risk of collapse of the foam structure.

The optimum porosity of foam concrete should be achieved by optimizing the interporous partitions and pore space in the volume. This is possible through the use of supplementary cementitious materials such as ground granulated blast furnace slag (GGBFS), फ्लाई खरानी, र सिलिका धुवाँ.

साथै, the amount of fly ash used in the foaming process can have a significant effect on the final quality of the product. The dry bulk density of foam concrete with 0-20% fly ash decreases, and it increases when the blending ratio of fly ash is 10-40%.
