Fosroc Auramix 300 — Mid PC Polycarboxylate Superplasticizer Concrete Admixture (200 kg)

Concrete mix design decisions rarely sit at the extremes — most structural work lands somewhere in the middle, where the right superplasticizer is neither the entry-level option nor the most aggressive high-PC system, but the mid-range grade that matches the actual performance demand without over-specifying or under-delivering. Fosroc Auramix 300 is exactly that product — the mid PC polycarboxylate superplasticizer in Fosroc's Auramix range, stepping up from Auramix 200 to deliver higher water reduction efficiency, better slump retention, and improved workability for concrete grades and applications that a low PC system doesn't fully cover.

The "300" grade in the Auramix range reflects a mid polycarboxylate concentration that brings real performance gains over low PC chemistry without the dosage sensitivity that comes with fully concentrated high PC systems. It's the grade that works well for M30 to M40 concrete, for pours where extended placement time is needed, for ready-mix batches covering longer transit routes in hot weather, and for any structural application where the workability window matters as much as the final strength figure. Concrete bleeding stays controlled, concrete segregation is minimised, and the concrete that lands on site is in the right condition to be placed correctly.

For contractors and ready-mix producers already using Auramix 200 for standard grades and needing a clear step up for more demanding mixes — Auramix 300 is the natural next specification within the same trusted product family. The consistency of working within one range matters practically too: similar handling, similar compatibility profile, similar dosage methodology, just calibrated for higher performance.

Backed by Fosroc's globally trusted construction chemical expertise and the Auramix range's position as Fosroc's dedicated polycarboxylate admixture family for Indian concrete — Auramix 300 gives concrete professionals the mid-range PC performance they need with the Fosroc quality assurance they rely on.
