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.
