Ordinary Portland Cement (OPC)
Ordinary Portland Cement (OPC) is a commonly used cement in the construction industry and is classified into grades 43 and 53, depending on strength and application. While Grade 43 OPC is mainly used for residential buildings and commercial construction, Grade 53 OPC happens to be a prime choice for high-strength structures such as bridges, high-rise buildings and highways.
Widely known for its quick setting time and high early strength, OPC is considered perfect for fast-tracked construction projects. The versatility and consistent quality of this cements make it one of the most reliable choices for a variety of construction applications with the assurance of the concrete remaining durable and strong under various conditions.
