Properties ofPROMPT NATURAL CEMENT
High resistance in aggressive environments
The mineralogical composition and low porosity of PROMPT natural cement give it durability properties such as long-term strength development, waterproofing, and resistance to aggressive water, seawater, and marine environments. It is therefore an ideal solution for water and sanitation sectors and marine environments.
In fact, Vicat PROMPT natural cement has the ability to resist acidic and pure waters, and sulfated water with a pH higher than 4. Furthermore, the physical and mineralogical properties provide mortars and concretes made with PROMPT natural cement excellent durability when in contact with seawater. It complies with the NF P15-314 standard "cement for marine works," achieved after tests spanning over 50 years.
This proven resistance to seawater, combined with its waterproofing properties, rapid setting, and hardening, makes it the ideal binder for work between tides or in total immersion. The work can even be performed in difficult or aggressive environments such as dykes, seawalls, boat ramps, and any other construction exposed to the sea, even in urgent situations, thanks to its quick setting time. It is also suitable for tall structures and emergency works in hazardous environments.
Furthermore, Vicat PROMPT natural cement has the ability to adapt to various water and sanitation structures, such as crack sealing, installation of watertight partitions, plugging of waterways, etc., thanks to its rapid setting and high strength. It can also be used for the repair of gutters, drains, inspection chambers, canals, cofferdams, as well as for the repair of mortar or concrete in sewers and wastewater treatment plants. These structures can be subject to physical and chemical aggressions that damage the concrete of pipelines and water treatment basins. It is therefore important to protect the concrete with a coating capable of withstanding these various aggressions and can be applied in a humid environment. Natural cement PROMPT is a suitable solution for these types of works due to its low permeability.
More information
Yes. Natural Prompt cement complies with the French standard NF P 15-317 "cement for marine works", validated after over 50 years of testing in real immersion. Its low porosity and mineralogical composition give it excellent resistance to sea water, sea spray and immersion cycles. It is suitable for dykes, revetments, slipways and any structure exposed to the marine environment.
Yes, this is even one of its historical fields of use. Sewers and wastewater treatment plants subject concrete to chemical aggressions (organic acids, sulphates, sulphides) and physical aggressions (abrasion). Natural Prompt cement is used for the repair and protective lining of these structures thanks to its low permeability and resistance to acidic waters. For very aggressive industrial wastewater, the compatibility with the pH must be checked on a case-by-case basis.
Natural Prompt cement resists acidic, pure and sulphate waters with a pH above 4. Below this threshold, the environment becomes too aggressive for its mineralogical characteristics. For structures exposed to waters with a pH below 4, specific technical solutions must be considered. For any precise assessment on a particular case, contact the Vicat technical department.
Yes, this is one of its reference applications. The combination of its rapid setting, hardening in a few minutes and resistance to sea water makes it possible to intervene in the narrow window between two tides. Mortar or pure paste can be implemented, harden and resist the next submersion without degradation. This capacity makes it the reference binder for marine projects in the intertidal zone.
