A liquid admixture that, when added to water during the preparation of concrete and mortars, and depending on the dose, acts as a plasticizer or a highly active agent reducing the amount of mixing water, ensuring high fluidity and improving the mechanical resistance of concrete and mortars.
Features
- does not contain chloride
- added directly to the mixing water or to the truck mixer on site
- ensures consistency of the mass, preventing the component from separating
- provides a reduction of the water / cement ratio, improving the properties of concrete and mortars
- improves the mechanical resistance of concrete and mortars
- improves concrete pouring, facilitates pumping and vibration
Application
- liquid concrete and mortars
- high-quality mortars and concrete for construction, for any type of application
- mortars and concrete that require a minimum water / cement ratio
- prefabricated and prestressed reinforced concrete elements
- pouring concrete in hot weather
