A price per ton of slag cement tells a batch plant almost nothing. What matters is the cementitious cost per cubic yard after replacement, and what the concrete does at 7 and 28 days. This page does that math in the open and quotes bulk loads delivered anywhere in Texas from the Houston grinding hub.
Same-day turnaround during business hours.
Assume 564 lb of cementitious per cubic yard, a common six-sack equivalent. Here is how much slag one 25-ton load covers at each replacement rate, and what that does to the portland line.
| Replacement rate | Slag per yard | Yards per 25-ton load | Portland saved per yard |
|---|---|---|---|
| 30% | 169 lb | ~295 | 169 lb |
| 40% | 226 lb | ~220 | 226 lb |
| 50% | 282 lb | ~175 | 282 lb |
| 70% (mass concrete only) | 395 lb | ~125 | 395 lb |
Slag cement generally prices below portland per ton in Houston because it is ground from a byproduct. Where it prices above, freight or a tight grinder is the reason. Either way the per-yard number is what decides, and we will run it with your actual mix.
Hasten supplies both, so there is no reason to oversell either. They are different tools.
About 1 to 2 percent retained on the No. 325 sieve. Higher 28 and 56 day strength, better sulfate and chloride resistance, lower permeability, lighter color, lower heat. Slightly slower set. Usually the better choice for durability specs, marine and below-grade work, and mass pours.
Carries its own calcium, so it sets without help and dries wet material. Usually the lowest cost per ton. Coal-plant supply is tightening as plants retire. The better choice for fast-turn platform work and where early strength drives the schedule.
Portland, slag and fly ash in one mix is common and TxDOT Item 421 Option 3 allows it. Slag brings durability, ash brings workability and cost. Many Texas producers run this way.
High replacement slows early strength, especially below 60 degrees. Finishing, stripping and cold-weather placement need to account for it. We will tell you where the line is for your mix rather than let you find it on a pour.
| Detail | What to expect |
|---|---|
| Load size | About 25 tons, bulk pneumatic tanker |
| Minimum | Full loads; under 20 tons is a shortload with a shortload fee |
| Houston metro | Next-day, subject to producer availability |
| DFW, Austin, San Antonio | Two to three days by truck; rail to a terminal for steady volume |
| South and West Texas | Quoted per job |
| Paperwork | Mill certificate with fineness and SO3, TxDOT producer code, SDS |
| Terms | Standard commercial terms |
Freight is the price outside Houston. The material costs the same in Dallas as in Houston. The difference is the truck. Standing volume by rail to a local terminal can cut that substantially for a plant that runs slag every week.
On high-sulfate clay, 5 percent slag cement with 1 percent lime replaces a 6 percent lime job and stops the heave. Different dosage, different economics, own page.
Loaded in Houston, delivered statewide by truck or rail.
At 564 lb of cementitious per yard: about 295 yards at 30 percent replacement, 220 at 40 percent, 175 at 50 percent. Send your mix and we will run the exact number.
Usually, per ton, in Houston. Outside Houston freight narrows the gap. The number that matters is cost per cubic yard after replacement, and we quote it that way.
Slag for durability, late strength, sulfate and chloride resistance, and mass concrete. Class C fly ash for fast set, workability, and lowest cost per ton. Many mixes use both. We supply both and will say which fits.
Full pneumatic tanker loads of about 25 tons. Under 20 tons is a shortload with a shortload fee.
Yes. We supply from a Houston producer on the TxDOT Slag Cement Material Producer List, DMS-4620, Grade 100 or better, with the producer code on every quote.
