 · Compressive strength test. This test is vital for evaluating the stone''s resistance to crushing loads. A wall stone has to bear the compressive load of the stone''s weight. A stone floor has to withstand loads of people and heavy objects. So, compressive strength is the highest load per unit area borne by the stone without giving in.

Stone Testing

since the strength may vary when the stone is wet, the strength tests (i.e. compressive strength, flexural strength, modulus of rupture) are sometimes performed using wet stone specimens. For the dry condition, the stone specimens are dried in an oven at 60°C ±2°C (140°F ±2°F) for at least 48 hours or

Kilkenny Limestone Technical Irish Blue Limestone

Chemical composition. Over 98% Calcite, 0.7% Dolomite, 0.7% Quarts, 0.2% organic Carbon, Less then 0.1% Iron Sulfite. Due to its extremely low Iron composite content, Irish blue limestone is suitable for use in pressurized urban or industrial environments without risk of compromising the stone through brown discolouration or staining.

The Suitability Of Limestone Aggregates For Use In ...

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.
