Building with stone: Limestone | Stone Specialist
18-06-2013· Portland and Bath stone generally exhibit compressive strengths of between 30 and 50MPa (megaPascals), which is similar to good quality concrete and more than sufficient for most purposes. Limestone is typically impressively strong under compression, like concrete, but exhibits flexural strengths of around one tenth of the compressive strength.

A higher compressive strength between1,800 psi (12.45 MPa) and 19,000 psi (131 MPa) means the stone can endure an upper crushing load. Dry or wet conditions as per load determine the compressive strength of the stone. Bending strength test This test is compulsory for knowing about the power of the stone in bending.

Physical Properties – McKeon Stone
The Irish Blue Limestone is a natural material and the physical properites reflect the conditions under which the stone originally formed and the subsequent geological history of Ireland. The best guarantee for the stone is its successful use as a building material in Ireland during the last 3000 years and the fact that many of the older structures built with it are still standing.

Limestone - Wikipedia
Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3). Dolomite, CaMg(CO 3) 2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare. However, the calcite in limestone often contains a few percent of magnesium.Calcite in limestone is divided into low

Strength of Stone Masonry - pressure, loads, center,
STRENGTH OF STONE MASONRY Compressive Strength.—Stone masonry varies widely in strength according to the character of the construction. The accuracy with which the joints are dressed, the strength of the mor tar, the bonding of the masonry and size of blocks of stone are more important than the strength of the stone itself.
