Louis Joseph Vicat , born the March 31st 1786 with Nevers, dead the April 10th 1861 with Grenoble, French, inventive engineer of the artificial cement.
Between with the Polytechnic school in 1804, then with the School of the Highways Departments in 1806.
He studies the mechanism of catch of natural limes and discovers their principles of hydraulicity on the building site of the bridge of Souillac. That allows the manufacture of artificial hydraulic lime and the natural cement as from 1817. He discovers the clinker, component of slow cement, and allows the artificial manufacture of the Portland cement (" white gold ") as from 1840.
He also invents the Aiguille Vicat which makes it possible to determine the time of catch.
Vicat did not take any patent, published a list of the careers to exploit cements, refused an armchair with the Academy of Science of Paris in order to continue his research; what was worth an international recognition to him.
