A slag-lime job needs two deliveries that land in the right order, slag cement dry to the grade, then lime within four hours. Hasten supplies both from Houston to any Texas jobsite and quotes the whole system, so the comparison to a lime job is one number.
Any Texas county.
| Material | Dose | How it arrives | Timing on site |
|---|---|---|---|
| Slag cement (GGBFS Grade 100) | 5% of dry soil weight | Bulk pneumatic tanker, about 25 tons, spread dry | First. Mixed until homogeneous |
| Lime | 1% (2% on fat clay, two-step) | Quicklime or hydrated lime, spread dry by pneumatic truck | Within four hours of finishing the slag mix; compact within two hours after |
| Water | To 2 points of optimum | Jobsite | With the lime, per the spec |
The four-hour window is the whole job. Slag placed and not activated in time is filler. We schedule the slag and the lime deliveries together, and we will not send the slag until the lime is confirmed.
Swell and strength numbers, four field sites, the ratio logic and the FM 3338 construction sequence, on one page.
Loaded in Houston, staged at Elgin, delivered to any Texas county.
Yes. Slag cement from a Houston producer on the TxDOT list, and lime as quicklime or hydrated lime, spread dry. We schedule them together so the four-hour window is met.
We quote the whole job from your acreage, depth and dosage. It is the only number that compares fairly to a lime job, because the dosages differ.
The slag is a qualified material under DMS-4620 and TxDOT has written a special provision for slag-lime stabilization on FM 3338. Acceptance under a given item is the district materials engineer's call.
County, square yards, depth, and the geotech. We will quote the whole job.
