Slag-Lime Stabilization: When Lime Alone Makes the Ground Rise

Field notes

The proposed workflow begins with sulfate and plasticity-index data, then limits lime to the amount needed to activate the slag reaction. The page gives a concrete comparison from College Station clay at 20,000 ppm sulfate: 5% slag cement plus 1% lime is listed at 7% swell, versus 42% for 6% lime alone. It also names field examples from TxDOT districts in Dallas and Laredo and provides a phone-based route for sending job details.
