·Autoclaved Aerated Concrete as a building material exists and has been industrially produced since the beginning of 20th century AAC stands for Autoclaved Aerated Concrete otherwise known as Aerated Cellular Concrete or Aircrete Early history of autoclaved aerated concrete is based on a series of process patents In 1880 a German
·Aspdin managed to invent his own cement mixture named Portland cement after Isle of Portland Like the term Roman cement the name Portland cement became a marketing scheme But Joseph Aspdin s son William was the con man Young William left Leeds to find his own way in London During this time there was a common
·The real breakthrough however came in 1824 when Joseph Aspdin a bricklayer from Leeds invented Portland cement Aspdin heated a mixture of finely ground limestone and clay until the carbon dioxide was removed The resulting product when mixed with water hardened into a substance as strong as Portland stone a popular building
Joseph Aspdin of England invented portland cement by burning finely ground chalk with finely divided clay in a lime kiln until carbon dioxide was driven off The sintered product was then ground and he called it portland cement named after the high quality building stones quarried at Portland England
·Concrete history is captivating and its role in modern society cannot be understated From its humble beginnings in ancient Egypt and Rome to the development of Portland cement in the 19th century and the advancements in reinforced precast and prestressed concrete in the 20th century concrete has evolved into a versatile and
The invention of Portland cement revolutionized the construction industry allowing for the creation of structures that were much stronger and more durable than those that had been built before This new cement was used to build structures such as the Hoover Dam the Panama Canal and the Empire State Building which still stand today as a
·Modern concrete is due to the invention of Portland Cement in 1824 by Joseph Aspdin Joseph called the product Portland cement because he believed set mortar made from it resembled the best Portland stone and Portland stone was the most prestigious building stone in use in England at the time says Stuart Galloway President

·1 Introduction Self healing is a well established and well known property of concrete due to its innate autogenous healing properties [] After a period of time fissures may mend due to the ongoing hydration of clinker minerals or carbonation of calcium hydroxide Ca OH 2 Autogenous healing on the other hand is restricted to minor
·A History of Cinder Block Invention The history of cinder block invention dates back to the late 19th century The first patent for a cinder block was issued in 1875 to George E Green of New York Green s patent was for a molded block of cement sand and other materials that could be used as a building material
·Reinforced concrete was invented during the second half of the 19th Century Besides the need to substitute wood for gardening and recreational use the main driver was the need for an economic and fireproof building material The development of modern cement
·In 1824 an Englishman named Joseph Aspdin invented Portland cement by burning chalk and finely ground clay in a kiln until carbon dioxide was removed He named cement after high quality building stones mined in Portland England This invention gave concrete a new life as it was now possible to reinforce it with iron or steel rods
·After Harmon Palmer invented the first commercially successful concrete block machine in 1900 the industry expanded rapidly with multiple manufacturers producing the blocks with their stone like surface created through either a mold or the use of special aggregates in the concrete mix The use of concrete to imitate stone started with its
