What is Type IL Portland Cement?

Type IL cement, also known as Portland-Limestone Cement (PLC), offers significant environmental benefits compared to other types of cement. Primarily, Type IL cement integrates a higher percentage of limestone into the cement mix, which results in a lower carbon footprint during its production. This reduction is primarily due to the decreased need for clinker, the component in cement production that requires the most energy and releases the most carbon dioxide (CO2). Research from various studies highlights that Type IL cement can maintain comparable performance characteristics to traditional Portland cement while significantly reducing greenhouse gas emissions and energy consumption. For example, a study from Louisiana demonstrated that Type IL cement showed less shrinkage and comparable compressive and flexural strengths to Type I cement, supporting its use in various construction applications (Rupnow & Icenogle, 2015). Furthermore, blending materials such as granulated copper slag with cement, as studied in China, showed a reduction in abiotic depletion and overall environmental impact (Zhang et al., 2022). Overall, these properties make Type IL cement a more sustainable choice for modern construction needs.
