    摘要: Binder compositions are provided which are principally composed of a lime-containing flyash, and optionally hydratable gypsum, with a small amount of a property improving additive. The compositions are capable of setting when mixed with sufficient water to form a hardened material having a high degree of compressive strength after only about 1 hour following set. In selected embodiments, compositions are provided for floor underlayment, road patch and exterior statuary applications. Compressive strengths starting at about 600 psi can be achieved within 1 hour after set with adequate working time for construction applications.
