12 commonly used building stones - their properties and,8. marble. marble belongs to the metamorphic category of rocks and it is formed when limestone is subjected to excessive heat and pressure. this process of forming is called metamorphism. marble is hard and compact in nature. it occurs in different colors and also it can take a good polish. its compressive strength is about 70 mpa..cylinder or cube: strength testing of 80 to 200 mpa (11.6,the continued advancement of concrete technology and the associated push to adapt advanced technology to production processes has resulted in the initial uses of 205 mpa (30 ksi) compressive strength concrete in the constructed environment. 1,2 producing concretes of this strength level presents a set of challenges to the concrete industry, many of which can be termed quality control/quality.

so, compressive strength is the highest load per unit area borne by the stone without giving in. 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

factors such as mix proportions, the water/cement ratio and curing conditions all affect the compressive strength of the concrete. the formula used to calculate compressive strength is: f = p/a. where: f = the compressive strength (mpa) p = maximum load (failure load) applied to the specimen (n)
marble is limestone that has been compacted and heated over millions of years. as a result, marble is less porous and slightly stronger than limestone, but still less durable than granite. depending on the limestone and the mineral combination within the marble, most marble rates from three to five on the mohs hardness scale.
samples of concrete with 0 to 15% marble dust replacement have reached optimum strength. finally showed that concrete containing marble dust 0 to 15% showed the highest amount of compressive strength, and split tensile strength of concrete.

as shown in table 3 the compressive strength of marble used in this study is huge reaching up to 1262 mpa averaging 1076 mpa however its tensile strength from dtt is apparently small being only 0714 mpa this huge difference between compressive and tensile behavior can be attributed to the microstructure of this kind of marble
the marble used for coating and transportation is expected to have a compressive strength value ≥49 mpa according to turkstat standards and a compressive strength value ≥52 mpa according to astm standards.
