Type III cement is generally preferred for High strength development, and are usually finer than the OPC/Type I cement. In India, which type of cement is classified under Type III?! Whether OPC 53 grade belong to this category?
Type III is a high early strength cement. It is ground finer and reacts faster than Type I, so the early strength gains are greater. However, the ultimate strength is not higher than Type I. Concrete made with Type III will have slightly higher 28 day strengths than concrete made with Type I, all else being equal. Type III is available in white or gray, but white Type III is difficult to find in small (less than pallet) quantities.
I dont think so that OPC 53 grade belongs to this category.
Please compare the properties / specifications of Type III cements with BIS specifications of different Indian cements and make a decision. One can conduct comparative studies on Type III and Indian cements to come to some practical conclusions
The ASTM has designated five types of portland cement, designated Types I-V. Physically and chemically, these cement types differ primarily in their content of C3A and in their fineness. In terms of performance, they differ primarily in the rate of early hydration and in their ability to resist sulfate attack.
