What it does
Polycarboxylate ether superplasticiser — the third-generation water-reducing admixture for concrete, mortars and self-compacting systems. Powder grade for dry-mix lines; allows 25–40% water reduction at constant workability.

Serica execution notes
- Water-reduction performance verified in a third-party lab on a reference mortar mix before container release.
- Grade matched to the buyer's existing PCE backbone (ether vs ester) so it slots into the current formulation without recalibration.
- DDP to gate · single European invoice.
- Verified per lot: solid content, chloride content, water-reduction / slump-flow performance, moisture.
