    Portland-Limestone Cement - National Precast Concrete,

    Portland-limestone cement (PLC) has comparable performance properties to ordinary portland cement but improves the environmental performance of concrete. PLC has been used in the United States on a limited scale in accordance with ASTM C1157 for several years, but itPortland - Limestone Cement,Portland‐Limestone cement (PLC) is a more sustainable building choice than regular Portland cement, but just as strong and durable: With up to 15% of the clinker used to produce regular Portland cement replaced by limestone, PLC manufacturing generates significantly lower greenhouse gas emissions and up to 10% fewer CO2 emissions.Raw Materials Used For Manufacturing of Cement,Raw materials used for manufacturing of Portland cement are found naturally in the earth crust. It is made primarily from calcareous materials, argillaceous materials and gypsum. Calcareous materials containing limestone or chalk and argillaceous materials containing an oxide of silica-alumina and iron are found as clay or shale.
