Concentrated liquid additive formulated for reducing shrinkage in cement mortar plastic phases. Reduces shrinkage by over 50% compared to the same mixture without additive, especially when conditions for curing are not possible in a humid environment. Excellent in combination with anti-shrinkage and structural fibres for the realization of works with high structural performances. It can be used in some thixotropic and castable structural mortars of the REPAR and GROUT families according to the quantities reported in the respective technical data sheets.

Add 4 to 6 kg of FLUID SRA for each cubic metre of mixture to be made (0.05 - 0.07 kg for each 25 kg bag of cement mortars of the REPAR and GROUT families).
For high volumetric stability mortars. Reduces cracking caused by shrinkage in cement mortar plastic phases. Reduction of free air shrinkage of some structural mortars of the REPAR and GROUT families (particularly useful when wet curing conditions of structural mortars are not possible).
FLUID SRA must be added to the mortar, after adding the mixing water to the cement mixer. After addition, mix appropriately before casting. The dosage of normal use is indicatively 1% with respect to the weight of the binders.
- To be added to other components
- Cement-based or lime-based mortars
Under normal conditions, use of the shrinkage reduction additive may lead to a reduction in the mechanical strength of the mixture up to a maximum of 10%. Use of the additive must, therefore, be approved by designer and mixture corrected according to required residual resistances.
