About — Quality AssuranceThe batch either passes
or it doesn't ship.
CFC runs in-house quality testing on every production batch. There is no grey zone: a batch that meets specification ships; one that doesn't is held. This is not a policy position — it's the only way to have customers who come back.
In-house testing.
No third-party delays.
The QA laboratory at Sadat City is part of the production facility — not a separate building or a contracted service. This matters. When we test a batch, the result comes back the same day. If there's a problem, production can investigate and re-batch without waiting for an external lab to post a report.
The lab handles testing for both the construction chemicals and metallurgical chemicals divisions. Construction products are tested against physical and chemical parameters — specific gravity, pH, chloride content, setting time, compressive strength development, and consistency. Metallurgical products are tested for chemical composition, granulometry, and, where applicable, activity in simulated foundry conditions.
Specific parameters,
not general impressions.
Every product at CFC has a defined specification — a set of measurable parameters with pass/fail thresholds. QA testing is not a general inspection; it's measurement against those thresholds. If a liquid admixture falls outside its specification range, that batch is held — not shipped with a note.
Testing isn't only at the end of the line. Incoming raw materials are checked against their own acceptance criteria before they enter a blend, so a problem is caught at intake rather than after a batch is made. The list below is representative of the parameters applied across the range; individual products carry their own complete specification documents, available on request.
Construction and
metallurgical products.
-
SG
Specific gravity (liquid admixtures) Measured by calibrated hydrometer on every batch — the primary indicator of correct dilution and ingredient ratio. Tolerance is held to ± 0.005 from the specification value.
-
pH
pH (liquid admixtures & waterproofing systems) Relevant to compatibility with cementitious mixes and to storage stability. Measured on each batch before packaging.
-
Cl⁻
Chloride content Chloride-free formulations are tested to confirm zero detectable chloride — critical for reinforced concrete where rebar corrosion is a risk.
-
ST
Setting time (cementitious products) Initial and final set are checked so the batch behaves as the datasheet states under working conditions.
-
CS
Compressive strength (cementitious products) Cube samples are cast at the time of each batch and tested at 24 h, 3 d, and 7 d, then compared against the product's strength-development curve.
-
BD
Bulk density (dry powder products) Measured by tared container for flux powders, dry admixtures, and repair mortars. Indicates correct blend density and the absence of segregation.
-
GS
Granulometry (metallurgical flux & inoculants) Particle size distribution is measured by sieve analysis for products where size affects performance in the furnace or mould.
-
CA
Chemical activity (foundry products) Selected metallurgical products are trialled in controlled melt conditions to verify degassing performance, flux action, or coating behaviour before release.
A batch that doesn't pass doesn't ship. That's not a difficult policy to describe — it's a difficult one to hold to when an order is late.
Batch records kept.
Every one.
Every CFC batch carries a batch number that links it to a production record. The record includes the date of production, the raw-material lot numbers used, the test results, the QA sign-off, and the despatch date. If a customer reports a problem on site, we can trace the batch within minutes — not because we expect problems, but because traceability is what makes investigation possible.
That same discipline is what keeps quality consistent batch to batch: the same inputs, the same checks, the same thresholds, every run. Batch records are retained for a minimum of five years. Technical datasheets — stating the specification, application guidance, and safety information — are issued with every order and can be downloaded from the product pages on this site.
We don't hide the numbers.
Technical datasheets are available for every product in the CFC catalogue. If you need a batch-specific test report for a project, ask us — it's part of the order.
