Building Stone Properties Classification Durability and

Stone must be of good appearance and uniform in colour; Stones light in colour resist weathering action better 2 Crushing Strength The crushing strength of stone should be greater than 100 N/mm2 Rock preference on the basis of Crushing strength: Igneous rocks > Metamorphic rocks > Sedimentary rocks These specifications also make specific reference to durability requirements for natural gravel and crushed stone and are based on various test methods with limits primarily suggested by Weinert (1980), PaigeGreen (1980), Venter (1980) and Sampson (1990) The test techniques specified include the 10% Fines Aggregate Crushing ValueDurability testing of basic crystalline rocks and What Is the Durability of Natural Stone? When we are going to define the durability of a material, it is the term used for an ability of a material to stay for a service life within the surrounding milieu, even without any damage or unforeseen maintenance requirement In simple words, natural stone should have resistance to variousThe Durability of Natural Stone All You Need to Know

Properties of Stones Requirements of Good Building

Strength is an important property to be looked into before selecting stone as a building block Indian standard code recommends, a minimum crushing strength of 35 N/mm 2 for any building block Table 1 shows the crushing strength of various stones Due to the nonuniformity of the material, usually, a factor of safety of 10 is used to find the permissible stress in a stone The more compact grained and heavier a stone the harder it is Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 3040% Being dry stones allow more crushing strength than when wet It is the ability of a stone to endure and maintain its essential and distinctive characteristics ie resistance to decay, strength andEngineering Properties of Stones and Tests on Stones Stones tests for durability of natural building stones At least three test pieces, each 50 mm cubes or 50 mm dia cylinders of 50 mm height shall he dried for Stones Tests:weathering,durability,water absorption

Tests on Building Stones Strength and Properties of
