Portland limestone cement is popular for three reasons. 1) When burning to form cement clinker, it consumes a lot of energy and releases a lot of carbon dioxide. Replacing cement clinker with limestone powder reduces carbon footprint by 10%. This increased focus on sustainability is one of the reasons why it has grown in popularity.
The initial production step in portland cement manufacturing is raw materials acquisition. Calcium, the element of highest concentration in portland cement, is obtained from a variety of calcareous raw materials, including limestone, chalk, marl, sea shells, aragonite, and an impure limestone known as "natural cement rock".

Xiong et al. [15] examined the impact of limestone powder (LP), quartzite powder (QP), and granite powder (GP) on the hydration of cement. The waste stone powders were found to possess the ability to replace cement, and all three powders could shorten the initial and final setting times of cement and reduce the heat of hydration.
