Rapid Hardening Portland Cement often referred to as RHPC, stands out as a remarkable type of cement renowned for its rapid strength development and quick hardening properties, surpassing the pace of conventional Portland cement. Its production involves finely grinding a material called clinker, derived from the high-temperature treatment of a mixture of limestone and clay, along with a small addition of gypsum.

It finds utility across a spectrum of construction applications, including repair tasks, the creation of concrete items within molds, and scenarios necessitating the prompt removal of molds.
