Cement clinker Type 1 , Type 2 and Type 3 Crown Portland Composite Cement is CEM-II/A-M which is a cement consisting of Clinker, Gypsum, Pulverized Fuel Ash (PFA), Blast Furnance Slag and Limestone designated by the specifications of BDS EN 197-1: 2003; CEM -II/A-M (V-S-L), 42.5 N. PCC is the most suitable cement for constructions in Bangladesh. CEM â?? II /A-M contains 80-94% Clinker, which is substantially higher than CEM â?? II/B-M containing 65 â?? 79% Clinker that provide us extra advantage in strength development and increase concrete performance. Both slag & fly ash (PFA) are used in PCC. Percentage of SiO2 in PFA is higher than slag which is advantageous to gain more long-term strength and ensure durable concrete. This type of cement is used for large constructions all around the world and it has been used during the last few decades. The hydration process of normal cement produces Calcium Silicate Hydrate CHS & Calcium Hydroxide Ca(OH)2. Calcium Hydroxide Ca(OH)2 does not contribute to gain strength and it is the weak part of reaction which is not suitable for concrete. Since PFA contains higher portion of reactive silica and slag contains alumina, it helps to convert Ca(OH)2 into CSH to gain further strength.
We can provide Clinker from Iran/UAE. We can show COA and BOL of current vessel performed this March 2020. If of interest and for further details, please as the DIRECT Buyer/End user, please send full details as per below, quantity required per month, etc. We will work on further details, on knowing the following: 1- Quantity per month? 2- FOB or if CFR, which discharge Port? 3- Discharge Rate? 4- Desired Laycan? 5- Payment Terms? Many thanks and look forward to your reply, having further discussions with you and assist you further with your next purchase. Regards Durgesh Dubey
We provide our clients Type-I Fresh Clinker directly from the manufacturer. Percentage composition of CaO & C3S in our clinker is as high as 65.90% & 59.72% respectively. In addition to this, we offer industrial cement clinkers which are checked strategically to ensure its compliance with the international quality norms and standards.z
In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter, produced by sintering (fused together without melting to the point of liquefaction) limestone and alumino-silicate materials such as clay during the cement kiln stage.

Product Description: Clinker, if stored in dry conditions, can be kept for several months without appreciable loss of quality. Because of this, and because it can easily be handled by ordinary mineral handling equipment, Clinker is also shipped to grinding plants in areas where cement-making raw materials are not available. Product Specification: Whiteness (Y Value): 77 - 78.5 Whiteness: 89 - 91 W.L.: 1160 - 1260 Free Lime: 0.8 - 1.5% LSF: 89.9 - 91 SIM: 3.5 - 3.9"
