12mm Aggregate (12mm Jelly) is one of the most commonly used coarse aggregates in Tamil Nadu construction. Ideal for concrete slabs, beams, columns, and foundations where the standard concrete mix design calls for a 12mm nominal maximum size. Produced from crushed granite and graded per ISI:383, it offers an excellent balance between workability, strength, and surface finish — the go-to aggregate for residential RCC works.
Available in bulk supply across Chennai, Chengalpattu, Kanchipuram, Thiruvallur, and all of Tamil Nadu. Delivered directly to your construction site in 24–48 hours. GST invoice provided on every order.
