It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to decay, strength and appearance. Physical properties such as density, compressive strength and porosity are measured in order to determine its durability. Durability is based upon the stones natural physical properties

This paper presents the research on the structure and compressive stress or compressive strength of mineral wool products. The products of chaotic, directional and combinative fibres structure have been studied visually and micro-scopically. During mechanical tests it was determined that compressive stress (compressive strength) of the stone wool

material is compressed between the platens of a testing machine as illustrated in Fig. 8.1. The compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material.

The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested after 28 days (fck). In field, compressive strength tests are also conducted at interim duration i.e. after 7 days to verify the anticipated compressive strength expected after 28 days.

Compression strength test of stone is determined in this type of test. Procedure: The sample taken for the test should be a cube of size 40mm×40mm×40mm or 50mm×50mm×50mm. The sides of the cubes are made smooth by dressing and polishing. The test should be carried out on dry as well as on saturated samples.

Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0). Lithology is commonly derived during log analysis, so m may be estimated (Table 1). What is needed still is an initial measure of rock strength provided by C 0.

Compressive Strength is a measurement of a materials resistance to Compressive Stress, which is created by any force applied to the stone mass. In the removable side of dental technology this compressive stress takes place when the completed wax-up of a given prosthesis is flasked, trial packed and then final packed (Hydraulic or Mechanical Axial Press) and pressed ( Hanau Flask Press ) for

The compressive strength of a stone determines its ability to withstand the weight of stacking on top of each other. A building stone’s compressive strength should be 60 to 200N/mm2. Location and composition determine a stone’s durability. The size, structure, and type of minerals in a stone make up its composition.
