It’s the calcium aluminate in Rapid Set Cement that makes for rapid hardening. The fast-setting, low shrinkage product, manufactured by Lafarge Cement – part of the Aggregate Industries business – is designed for use in screeds and renders to prepare wall and floor surfaces prior to installing most tile types. It’s suitable for dry and wet installations, including swimming pools, and can be pumped for fast application. Setting in just one hour, its rapid strength development means screeds can accept foot traffic after three hours and bonded screeds and renders can be tiled with ceramic tiles after four hours.
