Digging Deeper: Assessing the Impact of Limestone Exploitation and Use
The minerals featured in this cement are ye'elimite, an aluminous clay, gypsum, and limestone that is used as a filler. CSA cement distinguishes itself by releasing less carbon dioxide into the atmosphere when compared to other types of cement. Furthermore, it also consumes less energy due to the lower temperatures used in the kilns [71,72,73].

Impact of crushed limestone dust on concrete's properties
The use of crushed limestone dust may affect the properties of concrete. As per Celik and Marar [2] the inherent property of concrete to flow known as workability decreases with the use of crushed limestone dust. This is due to the presence of finer particles whose specific surface area is high, which absorbs more water and leads to a reduction in slump value.
