NEORETARD - Retardante de fraguado para morteros y hormigones

Neoquim Neoretard is a setting-retarder additive for mortars and concretes designed to extend the time available between mixing and the onset of hardening. Its use is particularly beneficial when longer working times are needed, when ambient temperature causes setting to proceed too rapidly, or when the job requires transporting, spreading, or placing the mixture for longer periods than usual.

The main advantage of Neoretard is the extended working time, allowing suitable working conditions to be maintained for a longer period. It can be particularly beneficial for large-scale concrete pours, pre-mixed mortars, work carried out during hot weather, or applications where it is necessary to coordinate multiple phases before initial hardening begins. Neoquim also specifies that its use does not alter the material’s final strength when applied correctly.

It must be added during mixing and distributed evenly throughout the entire mixture. The required amount depends on the desired delay time, the type of cement, the temperature, and the specific site conditions; therefore, the dosage must be adjusted according to Neoquim’s technical instructions.

An excess of retarder can unnecessarily prolong setting, so it is important to adhere to the prescribed dosage. Neoretard complements other additives in the Neoquim line—designed to control the behavior of concrete during placement—particularly well.
