Who invented Vicat apparatus?
The company was established in 1853 by Joseph Vicat (1821-1902), son of Louis Vicat, who invented artificial cement in 1817. His cement plant was at Genevrey-de-Vif south of Grenoble (Isère). It used an argillaceous limestone that Joseph Vicat had established as suitable by chemical analysis.
Who invented the artificial cement?
Louis Vicat
Louis Vicat, a graduate of École Polytechnique and École des Ponts, invented artificial cement in 1817. This discovery came at a time when he was faced with the challenge of building, at low cost, the Souillac bridge in Dordogne, the first bridge constructed using artificial hydraulic lime.

What is Vicat apparatus?
Definition of Vicat apparatus : a device for determining the normal consistency and time of setting of portland cements that consists of a rod weighing 300 grams, having a needle in each end, and supported in a frame with a graduated scale to measure the distance to which the needle penetrates the cement.
Who invented cement in India?
The common cement or Portland cement was prepared and Patented by Joseph Aspdin in 1824. In the later part of 19th century, cement production was taken up by many countries many decades after the first patent was taken by Aspdin in England.
Who is the father of concrete?

Why is Vicat apparatus used?
Vicat apparatus is generally used to determine the required quantity of water to produce a cement paste of normal or standard consistency. It is also used in the tests for initial setting time of cement or concrete and final setting time of cement or concrete.
What is Vicat needle?
The Vicat test is used for testing materials that have no real melting points. The main principle is that it measures the temperature at which a flat ended needle is able to penetrate the sample. This is known as the softening point of the material.
Why is called Portland cement?
The inventor Joseph Aspdin, of England, patented the basic process in 1824, naming it for the resemblance of the cement when set to portland stone, a limestone from the Isle of Portland.
When was cement first discovered?
1824
The precursor to modern-day cement was created in 1824 by Joseph Aspdin, a British bricklayer and builder, who experimented with heating limestone and clay until the mixture calcined, grinding it and then mixing it with water.

What is Vicat apparatus in civil engineering?
Vicat apparatus is a penetration device used in testing of hydraulic cements and similar materials to determine their normal or standard consistency. It is also used to determine the initial setting time and final setting time of hydraulic cements and similar materials.
What is Vicat used for?
Standard Vicat Apparatus has a reversible stainless steel plunger and needle assembly for 300g total weight. It is used to determine consistency and initial/final set times of cements and mortar pastes. This unit can be modified for testing to determine a false set.
What did Louis Vicat discover about cement?
Louis Vicat revealed the secrets of artificial cement in 1817 while building a bridge over the Dordogne River, between Souillac and Lanzac, in southwest France. He filed no patent and freely give advice to the architects and contractors of his time. His discoveries led to the development of the industrial manufacture of cement in the 19th century.
Who founded the company Vicat?
His son, Joseph Vicat, founded the company Vicat. Louis Vicat died. In 1889, he was one of the 72 scientists, engineers, and industrialists whose names were inscribed on the Eiffel Tower in recognition of their work or discoveries that honored France between 1789 and 1889.
What did Louis Vicat do?
Louis Vicat was awarded the title Knight of the Legion of Honor. His life’s devotion to the science of cement received national and international recognition. He entered the prestigious French Academy of Science in 1833.
Where did Louis Vicat go to school?
Louis Vicat enrolled at the École Polytechnique engineering school and graduated as an engineer of the Ponts et Chaussées school in 1809. Louis Vicat was assigned a mission in Souillac, in southwest France: building a bridge over the Dordogne River.
