Credibility in admixtures is earned batch by batch. CemBond tests to IS 9103:1999, ships a Certificate of Analysis with every dispatch, and conforms to ASTM C494 Type F.
Indian Standard for concrete admixtures. Every batch passes the uniformity test before dispatch.
High-range water-reducing admixture conformance for international and export specifications.
A Certificate of Analysis accompanies each dispatch, with batch coding for full traceability.
Incoming materials verified against specification before they enter the line.
Formulated and finished to grade recipe under controlled conditions.
Uniformity test: density, chloride, pH, solids and strength checks.
Batch-coded Certificate of Analysis issued and shipped with the order.
Compressive strength as a percentage of control concrete. All three grades exceed IS 9103 minimum requirements.

Figures from internal IS 9103:1999 uniformity testing. Site performance depends on cement, SCMs, aggregates and conditions, so always confirm by mix-design trial.
PCE and SNF do not mix. Cross-contamination of polycarboxylate-ether with residual naphthalene-based (SNF) admixture in shared mixer trucks, pumps or dosing lines can trigger flash set or severe slump loss.
We recommend dedicated or thoroughly flushed dosing equipment when switching admixture chemistries. It is the kind of non-obvious detail that protects a pour, and your relationship with the site.
Send us your grade, cement and site conditions. We will recommend the right PCE and arrange a trial sample.
