How Lime is Made
The limestone is heated as it moves down the kiln toward the lower end. As the preheated limestone moves through the kiln, it is "calcined" into lime. The lime is discharged from the kiln into a cooler where it is used to preheat the combustion air. Lime can either be sold as is or crushed to make hydrated lime.

Lime and its Production
There are three main ways of slaking the Quicklime: in an excess of water to produce a putty; in a shortfall of water to produce a powder - hydrated or bag lime; in damp sand to produce a hot mix. Lime carbonation Lime sets by absorbing water soluble Carbon Dioxide from the air. This process is called carbonation.

In the process of producing sustainable lime-based bricks with RCF and CRCF, it is essential to strike a balance between the Ca(OH) 2 content and the desired level of hydration. If the Ca(OH) 2 content is too low, the hydration degree remains insufficient. Conversely, excessive Ca(OH) 2 content is detrimental to the strength of the …
