Guaranteed Assay Parameters

Parameter	Guaranteed Range	Test Method	Significance
Tricalcium Silicate (C3S / Alite)	55.0% – 66.0%	Bogue Calculation / XRD	Dictates 28-day hydraulic compressive strength and early strength development.
Dicalcium Silicate (C2S / Belite)	12.0% – 20.0%	Bogue Calculation / XRD	Governs late-stage strength development (after 28 days) and hydration heat.
Tricalcium Aluminate (C3A)	7.0% – 11.0% (Grey) / <4.5% (Sulfate Resistant)	Bogue Calculation	Controls initial setting time and chemical resistance against sulfate attack.
Tetracalcium Aluminoferrite (C4AF)	9.0% – 14.0%	Bogue Calculation	Fluxing agent and source of grey coloration; lower in white clinker.
Free Calcium Oxide (Free Lime)	< 1.50% (Typically 0.8% – 1.2%)	Ethylene Glycol Extraction	Vital for volumetric stability and sound expansion (prevents autoclave expansion).
Loss on Ignition (LOI)	< 0.80% (Max 1.0%)	EN 196-2 / ASTM C114	Confirms complete calcination and minimal moisture uptake during voyage.
Liter Weight (Bulk Liter Density)	1,180 – 1,350 g/L	Standard Funnel Volumetric	Key indicator of burning degree and raw meal reactivity in the kiln.
Total Alkali Equivalent (Na2O + 0.658 K2O)	< 0.85%	Flame Photometry / XRF	Prevents damaging alkali-silica reactivity (ASR) in concrete aggregates.
