Clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker is ground to a fine powder and used as the binder in many cement products.
Clinker, in the manufacture of Portland Cement, is a granular substance that occurs as lumps or nodules, usually in the diameter of 3 to 25 millimeters. Clinker is available in grey, powdered, or lumps. Clinker with years of experience in providing the raw materials of cement Clinker, serving our customers from leading Cement factories. We have long-lasting, trusted relationships with our customers to supply various types of clinkers required for the production of Cement. Applications * The primary use of Clinker is in the production of cement. In the cement industry, the Clinker is also known as the Portland Cement Clinker.

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.

Cement clinker is a solid material produced in the manufacture of portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage
SRC is a type of cement where its clinker is blended with specific proportions of gypsum and bypass materials. This combination not only makes it durable against sulfate-induced damage but also provides a strong and reliable construction material.
SRC distinguishes itself by its minimal Tri Calcium Aluminate (C3A) content, a crucial characteristic. C3A is a chemical reaction with sulfate ions found in soil and water, which can lead to concrete expansion and cracking. As sulfate attack progresses, the affected concrete's strength and durability can significantly decrease. Sulfate attack can also manifest as surface scaling and deterioration of the concrete.
The concrete may become discolored, pitted, and crumbly. If sulfate attack continues unabated, it can lead to structural issues, including reduced loadbearing capacity, which can compromise the safety and integrity of the concrete structure. This unique property of SRC plays a vital role in inhibiting such expansion and cracking, strength and durability deterioration, especially in areas where the soil has elevated sulfate levels.
SRC is employed in a wide range of construction endeavors, including the infrastructure in sulphate-rich soils, construction of dams, coastal and marine structures like ports and platforms, sewage and Water treatment plants, repair and rehabilitation, underground Structures, and foundational work.
