Mechanical properties and electrical resistivity of portland limestone
This investigation explored the feasibility of producing strong, good quality, durable concrete in low-clinker systems (less than 50% clinker in some cases). The low-clinker content was achieved by combining interground portland limestone cement (PLC) with high limestone contents and different supplementary cementitious materials (SCMs).
