Limestone is a Sedimentary Rock Made up of the shells of millennia-old dead sea creatures Layers of these built up over millions of years and were squashed together until they formed Limestone. Limestone makes up about 10% of the total volume of Sedimentary Rocks The solubility of limestone in water and weak acid leads to a karst landscape, in which water erodes the limestone over the millions of years, most cave systems are through limestone bedrock The great pyramids of Egypt are, one of the seven wonders of the ancient world, its outside cover is made from limestone

Limestone : A sedimentary rock consisting primarily of calcium carbonate, often in the form of the minerals calcite or aragonite, and sometimes with magnesium carbonate in the form of dolomite. Minor amounts of silica, feldspar, pyrite, and clay may also be present. Limestone can occur in many colors but is usually white, gray, or black. It forms either through the accumulation and compaction of fossil shells or other calcium-carbonate based marine organisms, such as coral, or through the chemical precipitation of calcium carbonate out of sea water: used as a building stone and in the manufacture of cement, lime, etc.
CEMI 42.5 N Portland cement is used for ordinary purposes, as it is suitable for all uses that do not require certain properties, such as those available in other types, and it can be used in ordinary and reinforced concrete that is not exposed to certain effects such as sulfate salts found in soil and water, and it is a well-known and famous product around the world. This product is mainly made from grinding clinker and gypsum in compliance with Egyptian standards ES 4756-1/2013 and European EN 197-1/2011. Properties Cement produced according to Egyptian specifications ES 4756/1-2013 and European specifications EN 197/1-2011.
