Get a QuotationUnderground, sprayed concrete has to grip overhead rock and gain strength fast enough to support ground that will not wait. Accelerators and admixtures make that possible.
Set accelerators dosed at the nozzle flash-set the sprayed concrete so layers build overhead without sloughing, and early strength develops on the schedule ground support demands. The base mix uses superplasticizers for pumpability, and dosing balances build thickness against final strength, verified through the panel tests standard in tunnelling work.

Modern alkali-free grades protect crews and long-term strength compared with older chemistry. The TDS states dosage windows and strength effects.
Panel sprays and penetration or stud tests against the required strength-time curve. We can point your team to the standard procedure.
High dosages trade some final strength for speed, which is why dosing stays inside the TDS window and the mix design accounts for it.
