Abstract
Trona-accelerated composition for backfilling trenches are described. The compositions consist of aggregate (e.g., sand), Portland cement, Trona, water and sometimes air. The compositions may have a compressive strength of between 10 psi and 100 psi after 4 hours, a compressive strength of between 75 psi and 500 psi after 28 days, and a penetration resistance of between 4.5 tsf and 200 tsf after 4 hours. Also disclosed are methods of filling a trench with fast-setting flowable fill.

A composition using Trona for accelerating set times of the composition comprising:
- between 60% and 90% aggregate by weight of the composition, the percent aggregate by weight of the composition does not include Trona;
- between 3% and 25% Portland cement by weight of the composition;
- between 0.25% and 8% Trona by weight of the composition;
- and
- between 8% and 35% water by weight of the composition;
- the composition having a time to set of less than 1 hour, a compressive strength of between 10 psi and 100 psi after 4 hours, a compressive strength of between 75 psi and 600 psi after 28 days, and a penetration resistance of between 4.5 tsf and 200 tsf after 4 hours.
