Reinforced concrete was invented 1849 by Joseph Monier who received a patent in 1867 Joseph Monier was a Parisian gardener who made garden pots and tubs of concrete reinforced with an iron mesh Reinforced concrete combines the tensile or bendable strength of metal and the compressional strength of concrete to withstand heavy loads
Named after the strong building stones found in Portland England Portland cement was a revolutionary form of building material Its invention dates back to 1300 BC when builders in the Middle East discovered that coating the exterior of their fortresses with crushed clay and the walls of their houses with a thin wet layer of burnt limestone created a hard

Aspdin is credited with the invention of Portland Cement named after the Isle of Portland in Dorset where the limestone was quarried Gaining a patent in 1824 he went on to further innovate with his sons with their plant in operation until 1900 when it closed The key to their unique modification was the burning together of clay and
4 Portland cement is made up of four main compounds tricalcium silicate 3CaO · SiO2 dicalcium silicate 2CaO · SiO2 tricalcium aluminate 3CaO · Al2O3 and a tetra calcium aluminoferrite 4CaO · Al2O3Fe2O3 Cement Is Made Up Of Cement is a fine soft powder used as a binder because it hardens after contact with water
Cement is the sticky binding agent that s mixed with aggregates like sand and rock to create concrete So if concrete is like bread cement would be akin to flour How Is Portland Cement Made Portland cement is the most widely used basic component of concrete made by heating and cooling raw materials into a marble sized aggregate called
Egyptians in 2600 2500 BCE used gypsum based mortars These mortars cemented the Great Pyramids limestone blocks showcasing durability and precision Opus caementicium contains a natural cement created from volcanic ash mixed with lime which hardened upon setting Mesopotamians though less renowned made significant contributions too
A Concrete was used by the Romans but Roman concrete was made from lime pozzolan and aggregate John Smeaton also used such materials in 1756 to rebuild the Eddystone Lighthouse off the coast of Cornwall England and a number of others independently discovered the usefulness of such materials to make concrete during the ensuing 70 years or so
They were made out of the earliest form of concrete composed of mud straw and sticks Modern arch bridges made of concrete generally span up to a maximum of 800 feet What is concrete made from To make concrete a mixture of portland cement 10 15% and water 15 20% make a paste This paste is then mixed with aggregates 65 75% such as
