Vicat Prompt natural fast-setting Roman cement
Vicat Prompt Roman cement can be placed between natural hydraulic lime NHL 5 and Portland cement in terms of strength and hydraulic properties.
Thanks to the special composition of the clinker, it is a fast-setting cement that also hardens under water. In order to ensure the appropriate workability time, it requires a variable amount of natural setting retarder, e.g. citric acid.
The English engineer Smeaton first experienced in 1756 that burning limestone with a certain amount of clay and sand results in lime with increased strength, setting under water, and special properties, which he called Roman or Romanian cement.
The first practical application is attributed to Louis Vicat, who in 1822 used this material to build a bridge called "Pont Angouleme" over the Dordogne River in France according to a modified recipe, which was considered a technical feat at the time. Shortly afterwards, in the 1840s, the first building based on this technology was completed in Hungary, which was none other than the pillars of the Chain Bridge.
The use of Roman cement in Hungary reached its peak between 1870 and 1910.

The Vicat Prompt type Roman cement is made from natural, additive-free rock from a mine near Grenoble, which is provided with its unique properties by the firing temperature range between 600 and 1200 °C, which does not reach shrinkage (sintering).
Advantages of Vicat Prompt Roman cement:
- Natural, pure and additive-free fast-setting clinker.
Corrosion resistance and life capacity exceeding Portland cement, therefore it can also be used in sea water. - It has low shrinkage and, when mixed with natural lime, provides excellent vapor diffusion. • It has high adhesion to metals and natural stone, making it a suitable binder for the repair of monuments.
- It has a European-wide technical approval (ETA) for the repair of monuments.
- An indispensable cement in natural and organic architecture. Application: Masonry, adhesive and repair mortar, leveling and waterproofing mortar, screed based on natural binders, hemp concrete.
Application: Masonry, adhesive and repair mortar, leveling and waterproofing mortar, screed based on natural binders, hemp concrete.
Packaging: 25 kg bags on 1,500 kg pallets or 1,500 kg Big Bags.
