In most situations, using fly ash cement instead of Portland cement to manufacture concrete is a cost-effective option that increases the durability and workability of the concrete mix. This formula also reduces the amount of CO₂ emissions generated by cement production and recycles hazardous waste, instead of allowing it to sit in a landfill.

Normally in construction, nano clay is applied as an additive to enhance concrete properties. Morsy et al. [86] reported that, enhancement in compressive and tensile strength for mortar cement having nano clay as additive was recorded. Thermal behaviour of concrete also improved after nano clay was added as cement additive in …
