Portland Limestone Cement

What is Portland Limestone Cement?

Portland limestone cement (PLC) is an ASTM C595 general purpose blended cement containing between 5-15% limestone (Type IL). ASTM C150, ordinary portland cement standards, allow for up to 5% limestone replacement.

What Are The Benefits of Portland Limestone Cement?

Type IL portland-limestone cement reduces the amount of CO2 in the manufacturing process as compared to common ASTM C150 cements by approximately 10 percent while maintaining product performance requirements.

What are Some Product Applications?

Some common applications include:

  • Concrete Masonry Units
  • Architectural Precast Products
  • Custom Color Stucco Blends
  • Ready Mix Concrete
  • Precast Concrete

Type IL cement is not for use in areas subject to sulfates in soils. For precise product application it is important to refer to the project specification.

Contact with cement (including un-hardened concrete, mortar, wet cement, or cement admixtures) can cause skin irritation, severe chemical burns, or serious eye damage. Avoid contact with eyes and skin. Seek immediate medical attention if you have persistent or severe dis­comfort. In case of eye contact, flush with plenty of water for at least 15 minutes. Consult a physician immediately.

For other precautions please refer to the CalPortland Portland Cement SDS Report.
