Dong Son is a provider of Clinker Vietnam products to the Asia market with years of experience. To replicate that success, Dong Son Resources Co., Ltd will provide Clinker products with guaranteed quality meeting the needs of cement production as well as the needs of export to demanding markets where the company is implementing.
These minerals have different crystal structures and this determines the nature of the clinker. The quality of clinker will determine the nature of the cement.
With the advantage of the high-quality materials, Dong Son believes that they will provide the best meeting the ASTM (America) standard to produce types of cement with perfect quality.
Clinker to China: 3 day strength 30 by ASTM method

| SO3 | % | Max 1.0 | 0.30 | |
| Loss on Lgnition, (LOI) | % | Max 1.5 | 0.75 | |
| Free lime (F.CaO) | % | Max 1.5 | 1.4 | |
| Insoluble Residue | % | Max 0.75 | 0.42 | |
| Total alkalies (Na2O+0.658K2O) | % | Max 0.6 | 0.55 | |
| C3S | % | Min 55.0 | 63.18 | ASTM C150-11 |
| C2S | % | Max 21.5 | 15.18 | Calculated |
| C3A | % | Max 12.0 | 8.28 | |
| C4AF | % | Max 13.0 | 10.44 | |
| Lime Saturation Factor – LSF | % | Min 92 | 95.15 | |
| Moisture | % | Max 1.0 | 0.01 | Refer ASTM C136 |
| Particle Size: -Below 1mm | % | Max 10.0 | 7.82 | Sieve |
| – Above 30 mm | % | Max 10.0 | 6.50 | |
| Remark: C3S to be calculated based on gross CaO content. | ||||
| C3S = (4.071x %CaO) – (7.60x %SiO2) – (6.718 x Al2O3)- (1.43 x %Fe2O3)-(2.852xSO3) | ||||
| C2S = (2.867x% SiO2) – (0.7544x % C3S) | ||||
| C3A = (2.650x %Al2O3)-(1.692x Fe2O3); C4AF= 3.043 x % Fe2O3 | ||||
| LSF = (100 x % CaO) / (2.8 x %SiO2 + 1.18 x %Al2O3 + 0.65 x % Fe2O3) | ||||
