NRMCA Releases New CIP on Portland Limestone Cement

NRMCA's Concrete in Practice series is popular for its concise coverage of technical topics that can be provided by concrete producers to contractors, designers, testing technicians and other users. A new topic on Portland Limestone Cement (PLC) has been published and is now available. PLC is a blended cement that conforms to ASTM C595 specification for blended hydraulic cement. It is a good option to be considered by concrete producers for projects that require a reduced carbon footprint of concrete mixtures and for other performance-based reasons.
CIP 45 on PLC was developed by the NRMCA Research Engineering and Standards (RES) Committee in concert with the corresponding Portland Cement Association technical committee. It can be useful information to distribute to designers if specifications do not include a reference to ASTM C595 or otherwise do not permit the use of PLC.
The RES Committee has updated five other CIP topics:
- #3 - Crazing Concrete Surfaces
- #13 – Blisters on Concrete Slabs
- #18 – Radon Resistant Buildings
- #43 – Alkali Aggregate Reactions
- #44 – Durability Requirements for Concrete
CIP topics are periodically revised to ensure they include current information. They can be viewed and purchased here or by contacting Jacques Jenkins at jjenkins@nrmca.org.
