Abstract

Claims (17)

1. A method of filling a void with a quick set flowable fill composition comprising:

(a) mixing a quick set flowable fill composition comprising:

between 70% and 85% aggregate by weight of the composition;

between 5% and 15% Portland cement by weight of the composition;

between 1% and 5% sodium bicarbonate by weight of the composition;

between 8% and 15% water by weight of the composition; and

an air entraining agent;

the composition having a compressive strength of between 10 psi and 75 psi after 2 hours, a compressive strength of between 40 psi and 140 psi after 4 hours, a compressive strength of between 200 psi and 500 psi after 28 days, and a spread of 8 inches or greater; and

(b) filling the void with the composition.

2. The method of claim 1 , wherein the aggregate comprises sand.

3. The method of claim 2 , wherein the sand comprises a fine aggregate.
