The broad definition of a pozzolan imparts no bearing on the origin of the material, only on its capability of reacting with calcium hydroxide and water.... The general definition of a pozzolan embraces a large number of materials which vary widely in terms of origin, composition and properties. - http://en.wikipedia.org/wiki/Pozzolanhttp://inspire.ec.europa.eu/codelist/CommodityCodeValue/pumice2015-08-18 18:07 PM CEST2015-08-18 18:07 PM CESTpumiceA volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. It is typically light colored. Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles and thicker vesicle walls and being dark colored and denser. - http://en.wikipedia.org/wiki/Pumicehttp://inspire.ec.europa.eu/codelist/CommodityCodeValue/shellGrit2015-08-18 18:07 PM CEST2015-08-18 18:07 PM CESTshell gritShell grit is coarsely ground or broken seashells.

Included in this category are limestone, dolomite, dolomitic limestone, and travertine, which is a calcitic rock that is precipitated from hot springs. http://minerals.usgs.gov/minerals/pubs/commodity/stone_dimension/myb1-2007-stond.pdfhttp://inspire.ec.europa.eu/codelist/CommodityCodeValue/marble2015-08-18 18:07 PM CEST2015-08-18 18:07 PM CESTmarbleCommercial marble includes metamorphosed limestones and serpentine rocks, all of which are capable of taking a polish. An important member of this classification is serpentine marble, which is also known as verde antique, and comprises green-to-black serpentine, which is a hydrous magnesium silicate mineral that is crisscrossed by veins of lighter minerals, such as calcite or dolomite. http://minerals.usgs.gov/minerals/pubs/commodity/stone_dimension/myb1-2007-stond.pdf
