Dallas-Fort Worth is the largest concrete market in Texas and the place where TxDOT's sulfate-heave research began. Neither fact changes where slag cement comes from: every grinder in the state is in Houston. Hasten loads there and delivers to DFW by truck or rail, priced delivered, for concrete producers and for the stabilization contractors working the Eagle Ford belt.
Same-day turnaround during business hours.
Replacement of 35 to 50 percent portland under TxDOT Item 421, up to 70 percent in mass concrete. Lower heat, higher late strength, better durability. DFW producers run slag every day; the question is freight, and rail to a terminal answers it for standing volume.
TxDOT's own guidance puts the most severe sulfate heaves from Dallas-Fort Worth down Interstate 35 on the Eagle Ford formation. Lime alone heaves those soils. Five percent slag cement with 1 percent lime does not. This is the market where slag is a necessity, not a cost play.
Field sections from TxDOT project 0-4240, all in the Dallas District.
| Site | Sulfate | What happened |
|---|---|---|
| SH 161, Dallas County | 21,000 to 27,000 ppm | Six percent lime swelled 40 percent, four times the untreated soil. Slag-lime swelled 4 percent below untreated |
| SH 183, Dallas County | 20,000 to 30,000 ppm | Six percent lime swelled 35 percent. Slag-lime swelled 6 percent below untreated |
| US 67 west of Midlothian, Ellis County | Selenitic Eagle Ford | Documented heave failure; formation flagged in the Geologic Atlas before construction |
| US 82 near Sherman, Grayson County | 4,160 ppm at surface, 27,840 at 41 inches | Gypsum concentrates at depth; test again after the site is at grade |
What this means on a DFW bid: if the geotech shows sulfate above about 7,000 ppm anywhere on the alignment, lime alone is the wrong answer and the district knows it. Slag cement with 1 percent lime is the researched fix, and the placement sequence is on slaglimestabilization.com.
| Detail | What to expect |
|---|---|
| Source | Houston producer on the TxDOT DMS-4620 list, Grade 100 or better |
| Truck | Bulk pneumatic tanker, about 25 tons, two to three days from order |
| Rail | To a DFW terminal for standing weekly volume; ask and we will price it |
| Minimum | Full loads; under 20 tons is a shortload with a shortload fee |
| Paperwork | Mill certificate with fineness and SO3, producer code for the district, SDS |
| Quote | Same business day, delivered to your city |
Freight is the price in DFW. The material costs the same in Dallas as in Houston. A standing order by rail cuts the delivered cost meaningfully for a plant that runs slag every week. Call 832-655-7763 with your volume.

Truck and rail from Houston to the whole Metroplex and north to Sherman.
No. Every slag cement grinder and import terminal in Texas is in Houston. Slag sold in DFW arrives by truck or rail from Houston, or by rail from out of state. Hasten loads in Houston and quotes delivered.
Two to three days by truck for a standard 25-ton load. Rail to a local terminal for standing weekly volume, priced per job.
Clay along the Eagle Ford formation carries gypsum. Lime alone reacts with it to form ettringite and heaves the ground, which is what happened on SH 161 and SH 183. TxDOT research found 5 percent slag cement with 1 percent lime controlled swell where lime alone failed.
Yes. We supply from a Houston producer on the TxDOT Slag Cement Material Producer List, DMS-4620, with the producer code on every quote.
Full pneumatic tanker loads of about 25 tons. Under 20 tons is a shortload with a shortload fee.
