Portland limestone cements (PLCs) have recently been approved as a part of the ASTM
C595/AASHTO M240 specifications. These cements are designed to enable more
sustainable concrete production by replacing up to 15% of the clinker with interground
limestone particles. The PLCs represent a potential method to reduce the carbon dioxide
embodied in built infrastructure and extend the life of limestone quarries. This paper
presents a comparison of the performance of three commercially available PLCs meeting …

Performance of portland limestone cements: Cements designed to be more sustainable that include up to 15% limestone addition

TJ Barrett - 2013 - search.proquest.com
In 2009, ASTM and AASHTO permitted the use of up to 5% interground limestone in ordinary
portland cement (OPC) as a part of a change to ASTM C150/AASHTO M85. When this work
was initiated a new proposal was being discussed that would enable up to 15% interground
limestone cement to be considered in ASTM C595/AASHTO M234. This work served to
provide rapid feedback to the state department of transportation and concrete industry for
use in discussions regarding these specifications. Since the time this work was initiated …
