The Suitability Of Limestone Aggregates For Use In

Limestone Aggregate in Concrete. Because limestone aggregate is normally comprised of crushed fragments, the better surface texture and higher angularity that obtains lead to good bond with the cement and good particle interlock, both of which help in achieving good compressive strength properties.
