Products, including treatment compositions, and methods for improving cement performance are provided. More specifically, products and methods for improving cement hydration, and thus cement performance, using vegetation are provided. The vegetation may be processed into a vegetative extract that may be used to create a treatment composition. The treatment composition may be used to enhance hydration of cement. The products and methods disclosed herein may be used to create a stronger, lower cost, and longer-lasting cementitious product.

Expansive 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, for example, a plurality of amorphous α-dicalcium silicate hydrate nanoparticles or microparticles. The MAHBM may be used as an expansion agent in a cement composition or used as an expansive cement by itself.
