Fly ash bricks are manufactured by mixing water, quarry dust/river sand, Thermal conductivity: They do not absorb heat and give maximum light reflection. Sound Insulation: It provides an acceptable degree of sound insulation. Fire and Vermin Resistance: They have good fire resistance, it has no problem with vermin attacks. Durability and moisture content: These blocks are highly durable
For a concrete sample with a w/cm of 0.5 with 75% fly ash, the thermal conductivity was reduced by 19%. Density and thermal conductivity are often positively correlated. Fly ash has a much lower density than cement, therefore samples with a higher percentage of fly ash had lower densities and subsequently lower thermal conductivities.
Experimental results show that the thermal conductivity of the bricks is 0.36 W/m•K ± 6.5%, specific heat is 857 J/kg•K ± 5.1%, thermal diffusivity is 3.21 x 10-7 m2/s ± 9.1%, and coefficient of thermal expansion is 5.15 K-1 ± 9.3%. These values are lower than those of clay bricks.
