What are the cement classifications for Portland Limestone Cement? Depending on the particular type of PLC, the cement may be classified as moderate sulfate resistant, high sulfate resistant, moderate heat of hydration, or low heat of hydration similar to ASTM C150 portland cement (see Figure A, right). ASTM C150/AASHTO M85: Type I Normal
Portland cements: Clinker, gypsum and limestone---but with about 10% additional limestone. • Portland-limestone cements have been used under the ASTM C1157 Performance Specification for the last 20 years • Portland-Limestone cements were added to CSA A3001 in 2008, with up to 15% intergroundlimestone replacing cement clinker …
Incorporating limestone fines and quarry waste into concrete mixes not only aligns with sustainability goals but also meets the stringent requirements outlined in BSEN 7979. This European standard sets forth specifications for the use of alternative materials in concrete production, ensuring their compatibility, quality, and performance.
Concrete and mortar made of limestone can react to the carbon dioxide in rainwater and wear away. The resulting damage takes the form of gaps between bricks and buildings, which must be repaired by filling in the gaps. Burning fossil fuels can increase the rain's acidity, which further damages limestone. ...
Cement—the key ingredient that gives concrete its strength—is produced by burning limestone in kilns at 2,300° to 3,000° F (1,260° to 1,650° C). The process typically uses powdered coal or natural gas as fuel, consuming a large amount of energy and releasing carbon dioxide (CO 2 ) from the combustion.
For flatwork, though, strength is seldom the controlling factor, because higher-strength concrete mixes that produce very stiff concrete can result in more shrinkage which shows up as curling and cracking. However, synthetic fibers have proven to be beneficial as a way to reduce shrinkage cracks. Fibers will not provide structural reinforcement ...

1 Replacement fine aggregate by crushed limestone reduces workability of concrete mixes especially in leaner mixes (poor). 2 Concrete mixes with crushed limestone fine aggregate needs more water to maintain the same workability than that of natural sand. The amounts of needed water are rather not high ranging about (5-10)% of cement quantity.
Limestone aggregate concrete tends to be more durable and resistant to weathering than traditional concrete mixes. This enhanced durability reduces the need for maintenance, repairs, and eventual replacement, thereby further decreasing the overall environmental impact over the structure's life cycle.
