Limestone Filler - an overview ScienceDirect Topics

2003-1-28  Limestone fillers are being used increasingly in cements and, more recently, as a mixer addition. EN197-1 (BS EN197-1, 2000) contains two classes of Limestone Portland cement, CEM II/A-L (or LL) and II/B-L (or LL).The former contains between 6 per cent and 20 per cent limestone and the latter 21–35 per cent limestone. This material is interground with the Portland cement clinker, which ...

What is limestone and how is it formed? – SidmartinBio

2020-4-10  What is limestone and how is it formed? L imestone is a sedimentary rock, which means it was formed from small particles of rock or stone that have been compacted by pressure. The water pressure compacts the sediment, creating limestone. The area around the Great Lakes, such as Michigan, Indiana, and Illinois, has a large amount of limestone.
