Cenospheres can increase the thermal insulation of the product. They are fire-resistant, used as an additive in drilling mud in the wells, and augment the lifespan of drilling equipment. They have low density (0.60 - 0.70 g/cc) and high compressing strength (2000 - 4800 psi). They are insulative, innoxious, waterproof, hard, and rigid substances.

Cenospheres are spherical particles found abundantly in fly ash. The density of cenospheres varies between 0.4 and 0.72 g cm −3 . The skeleton of the cenospheres is made up of aluminosilicate, and the shell structure is a complex layered nano-size film with thickness of 30–50 nm ( Ranjbar and Kuenzel, 2017 ; Danish and Mosaberpanah, 2020 ).

The observed outcomes have demonstrated the better compatibility of using fly ash up to 25% and cenospheres at 30% as a sand replacement in LWC with improved strength characteristics. In the construction of concrete structures, Light Weight Concrete (LWC) is quickly gaining acceptance for a variety of uses. When building concrete …

Cenospheres are spherical particles with a hollow center. Their concentration in fly ash varies over a wide range, from 0.01 to 4.80 wt%; but in most cases limits between 0.3 and 1.5 wt% [12], [13], [14]. The formation of cenospheres during combustion depends on the total mineral content of the feed coal and the combustion process [15], [16].
