{"product_id":"auramix-400","title":"Fosroc Auramix 400 — High-Performance Mid PC Polycarboxylate Superplasticizer | Fosroc India (250 kg)","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eEvery admixture range has a flagship — the grade that defines the ceiling of what the product family can do before stepping into a different chemistry tier entirely. In Fosroc's Auramix polycarboxylate \u003cstrong\u003esuperplasticizer\u003c\/strong\u003e range, Auramix 400 is that product. It's the highest-performing grade in the Auramix mid PC family, pushing the water reduction capability, slump retention, and workability enhancement of polycarboxylate chemistry to the upper limit of what mid PC concentration delivers — and for the concrete applications it's designed for, that ceiling is exactly where the specification needs to sit.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe concrete work that genuinely needs Auramix 400 is the kind where getting workability wrong isn't a quality inconvenience — it's a structural risk. Very high-grade concrete (M50 and above), self-compacting concrete formulations, heavily reinforced elements where the mix has to flow around congested steel without vibration assistance, large-volume infrastructure pours where placement windows are extended by necessity — these are the applications where Auramix 400 earns its place in the mix design. The \u003cstrong\u003eadmixture\u003c\/strong\u003e delivers water-cement ratios that high-strength design targets require while maintaining the fluidity that makes placement on real sites actually achievable.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eConcrete bleeding\u003c\/strong\u003e is controlled even at high workability levels, \u003cstrong\u003econcrete segregation\u003c\/strong\u003e stays in check, and the mix retains workability long enough to be placed correctly without reverting to water addition — which at M50 grades would be disastrous for the structural outcome. The polycarboxylate chemistry at this concentration disperses cement particles thoroughly enough to achieve all of this simultaneously, something SNF chemistry at equivalent dosage simply cannot match.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFor ready-mix producers, infrastructure contractors, and precast manufacturers working at the demanding end of the concrete grade spectrum — Auramix 400 is the \u003cstrong\u003econstruction chemical\u003c\/strong\u003e specification that closes the gap between what mix design theory requires and what site conditions can practically deliver. Backed by Fosroc's globally trusted expertise and the Auramix range's established track record on Indian construction projects.\u003c\/p\u003e","brand":"Fosroc Chemicals India Pvt.
