Limestone And Cement Project

Research projects have shown that even up to 30 mass dolomitic limestone in cements resulted in a comparable performance of cement and concrete to those made with reference calcitic limestone. As an example Figure 1 shows that the scaling criteria were easily met in every case when dolomitic limestone-containing cements were used.
