By implementing limestone powder as a replacement for cement, the environmental effect can be reduced. The environmental effects of replacing cement with limestone powder will differ based on the particle size used because finer limestone powder requires additional milling.
After the limestone rocks are processed, they are transported to a lime kiln for calcination. This is the process where the limestone is heated to a temperature above 1,472ºF for decarbonation, i.e., removal of carbon dioxide in gaseous form, to produce quicklime. Almost half of the limestone
The process by which limestone (calcium carbonate) is converted to quicklime by heating, then to slaked lime by hydration, and naturally reverts to calcium carbonate by carbonation is called the lime cycle. The conditions and compounds present during each step of the lime cycle have a strong influence of the end product, thus the complex and varied physical nature of lime products.

This paper reports the experimental study undertaken to investigate the influence of partial replacement of sand with limestone waste (LSW), with marble powder (M.P) as an additive on the concrete properties. The replacement proportion of sand with limestone waste, 25%, 50%, and 75% were practiced in the concrete mixes except in the concrete mix.
However, instead of leaving the powder as is, pelletized lime takes the process onestep further, combining the lime with adhesives, called lignosulfonates, to bond the lime particles together and form pellets. These lignosulfonates account for about 9 percent of the entire composition of each pellet, and dissolve in the presence of water.
