Abstract:
Cement compositions for use in subterranean wellbores that include a monophase amorphous hydraulic binder material (MAHBM). The MAHBM may include a plurality of particles having a silica core and an amorphous coating substantially surrounding the silica core. The coating may comprise a plurality of amorphous particles, such as α-dicalcium silicate hydrate nanoparticles or microparticles. The MAHBM may be used as a strength retrogression mitigating additive in a cement composition or used as a high temperature cement.
