CONTROLLED LOW STRENGTH FLOWABLE FILL COMPOSITION

摘要

A rapid setting, controlled low strength composition of Class C fly ash is provided having a quantity of hydrated lime in an amount sufficient to accelerate the hydration and set time of the fly ash. In some examples, a filler material is added. A method for acceleration of the hydration and set time of a cementitious mixture is provided wherein hydrated lime is added to the cementitious mixture in an amount in the range of 0.1% to 5% by weight of the cementitious material. Further, a calcium source may be added to a Class C fly ash to accelerate the hydration and set time of the ash.
