	Joseph Aspdin Summary
		Aspdin discovered that the key to making hydraulic cement (cement that would harden when mixed with water) was roasting a mixture of clay and limestone powder in a furnace.
		Joseph Aspdin (1788 – 20 March 1855) was a British mason, bricklayer and inventor who patented Portland cement on 21 October 1824.
		In 1853 William Aspdin fled his creditors and went to Germany where he was involved with several cement works of which the last one developed as the foundation for the Alsen Group which was a large exporter to USA and also Australia prior to 1900.

	Illumination \| Spring 2005
		When Englishman Joseph Aspdin patented his breakthrough cement mix in 1824, he proudly dubbed it "portland" because the color of the concrete it produced reminded him of beautiful stone quarried on the Isle of Portland, a limestone peninsula in the English Channel.
		Joseph Aspdin, a mason and brick layer by trade, made his mark on this distinguished history by "rediscovering" what the Romans knew: that pulverizing a controlled portion of limestone and clay together changed the chemical properties of both.
		Aspdin jealously guarded the details of his process, even to the point of building 20-foot-high walls around his Wakefield, England, plant.

		Aspdin, whose son worked with him, in fact had little scientific or chemical knowledge and used rule-of-thumb methods.
		Be that as it may, Aspdin was granted a patent for "Portland cement" - so called because its colour resembled that of Portland stone.
		Aspdin's 'Beehive' kiln, used to make the first genuine Portland Cement, can still be seen at Northfleet.

	Portland Cement -- Monday, Oct. 27, 1924 -- Page 1 -- TIME
		It was in Leeds, England, 100 years ago, that Joseph Aspdin discovered that a new building material could be produced by mixing pulverized lime and clay in correct proportions and driving out the carbonic acid gas with heat.
		Aspdin was not a chemist or scientist; and his momentous discovery was made by accidental experimentation.
		Aspdin named his material "Portland cement" because of its resemblance to a type of building stone then commonly quarried on the Isle of Portland.

		The inventor heated a mixture of finely ground limestone and clay in his kitchen and ground the mixture into a powder creating a hydraulic cement â“ one that hardens with the addition of water.
		With this invention, Aspdin laid the foundation for today's portland cement industry.
		The first large use of this modern-day portland cement, and its first engineering use, was in a tunnel under the Thames River in 1828.

	Cement Industry

		The portland is consolidated today, as Aspdin it predetermined and carefully it provided the chemical combination of calcium, silicon, iron and aluminum.
		Other research is transforming Joseph Aspdin's "artificial stone" into wholly new products with properties that rival plastic, aluminum, and ceramics.

	WHAT IS CEMENT
		Because the ingredients of natural cement were mixed by nature, its properties varied as widely as the natural resources from which it was made.
		Portland cement today, as in Aspdin's day, is a predetermined and carefully proportioned chemical combination of calcium, silicon, iron, and aluminum.
		But it was almost 20 years later when J. White and Sons set up a prosperous factory in Kent that the portland cement industry saw its greatest period of early expansion, not only in England, but also in Belgium and Germany.

		John Smeaton, who was assigned to rebuild the Eddystone Lighthouse in 1756, is known to be the first one to realize the chemical properties of lime.
		The subsequent development was the invention of the binder called the “Roman Cement", by Joseph Parker.
		Although the binder improved extensively in the following years, the “Portland” name was maintained as is. Since the binder invented by Joseph Aspdin was not baked at adequately high temperatures, it never reached the properties of today’s Portland cement.

		The British furthered the evolution of concrete in 1824, when a Leeds bricklayer, Joseph Aspdin, invented Portland cement, so called because the resulting concrete looked to him like stone quarried on the Isle of Portland.

		Portland cement was invented in 1824 by British mason Joseph Aspdin.It stands in contrast to " Roman " cement.
		When water is added, they rearrange their structure and interact chemically to form interlocking crystals of calcium - aluminum - silicates that bind together the particles of sand or stone.

	CONCRETE (Site not responding. Last check: 2007-10-15)
		The first major concrete users were the Egyptians in around 2,500 BC and the Romans from 300 BC The Romans found that by mixing a pink sand-like material which they obtained from Pozzuoli with their normal lime-based concretes they obtained a far stronger material.
		Lime and Pozzolana concretes continued to be used intermittently for nearly two millennia before the next major development occurred in 1824 when Joseph Aspdin of Leeds took out a patent for the manufacture of Portland cement, so named because of its close resemblance to Portland stone.
		The use of burning lime and pozzolan (admixture) was lost, but reintroduced in the 1300's.

		The origins of hydraulic cements go back to classical Greece and Rome, when lime and volcanic ash were mixed to form a hard monolithic mass.
		However, the invention of Portland cement is widely credited to Joseph Aspdin, an English mason.
		Aspdin patented it in 1824 and named his product Portland cement because its gray color resembled the color of limestone quarried on the Isle of Portland in Great Britain.
