Tested & Proven

PLC has been subjected to extensive research and testing by industry, both in the U.S. and elsewhere. Researchers have studied fresh properties related to placing and finishing, as well as hardened properties that relate to durability. There is a wealth of published literature including both laboratory research studies and real-world installations that has been compiled to provide background technical information for engineers, specifiers, and other concrete technologists on use of portland-limestone cements.

​

Areas studied include resistance to scaling and freeze-thaw, chlorides, sulfates, and alkali-silica reaction.  Each type of exposure has been thoroughly investigated to confirm that PLC produces strong, durable concrete.

​

Just like concrete made with portland cements, concrete mixtures made with PLC should be tested to confirm fresh and hardened properties such as air void content, strength, freeze-thaw durability, and sulfate resistance, as needed for each project.
