  Rapid hardening cement is a type of   grey cement   designed to achieve high early strength, which makes it suitable for quick construction projects. Unlike ordinary concrete cement, which takes longer to gain strength, rapid hardening cement achieves similar compressive strength in a much shorter time. This feature is achieved through modifications in the cement’s composition, which also enhances its durability and resistance. Construction projects, where time is of the essence, for example – road repairs, precast concrete, or emergency repairs benefit from this type of cement. Composition of Rapid Hardening Cement Rapid hardening cement contains specific ingredients that enhance its early strength and durability. They include: High Tricalcium Silicate (C3S): Approximately 60% of C3S promotes faster hydration and allows the cement to achieve high early strength within a short time. Lower Dicalcium Silicate (C2S): At around 15%, the reduced amount of C2S contributes to ...

  Types of Cement and Their Uses Cement can be categorised into two main types – hydraulic and non-hydraulic cement.  Hydraulic cement is formed by the reaction of powdered cement with water. You can use it for all types of construction, including underwater construction projects. Non-hydraulic cement sets and becomes adhesive due to carbonation. You can use it for various construction projects, except underwater construction projects.  Hydraulic cement is the most commonly used cement. Portland cement is a type of hydraulic cement that’s been a preferred choice for architects, engineers, and constructors. The primary reason behind its popularity is its ability to harden quickly.   Per the Bureau of Indian Standards (BIS), the different types of Portland cement are as follows: Ordinary Portland Cement (OPC) When Portland cement clinker is mixed with gypsum, it forms OPC. OPC is further divided into three types, depending on their grade. The grade of ...
