Use jalli 20mm as per your engineer’s mix design. For concrete, mix the aggregate with cement, sand and water in recommended ratios. For foundations and road sub-base, spread evenly, then compact using a vibrator or roller. Always store on a clean, dry surface and avoid mixing with soil or debris.

20mm jalli is mainly used as a coarse aggregate in concrete mixes, foundations and road work. Its size makes it ideal for RCC slabs, beams, columns, floor concreting and pavement sub-base layers. It provides strength, stability and proper drainage, making it suitable for both residential and commercial construction projects.

Both 12mm and 20mm aggregates are used in concrete, but 20mm jalli is generally preferred for structural members like beams, slabs and foundations because it gives better load distribution and reduces cement consumption. 12mm aggregate is often used for thinner sections or where a smoother finish and tighter reinforcement spacing are required.

For most standard structural concrete, 20mm aggregate is considered the best size because it offers a good balance between workability, strength and economy. Jalli 20mm allows proper compaction and reduces voids. However, specific projects may use 10mm or 12mm aggregate where thinner sections or intricate reinforcement detailing are involved.

Yes, 20mm jalli is commonly used in road construction as a base or sub-base material. Its angular shape and graded size provide excellent interlocking and load-bearing capacity. When properly compacted, 20mm aggregate helps create a stable foundation layer, improving road durability, drainage and resistance to rutting under traffic loads.

One ton of 20mm aggregate generally covers around 10–12 square feet at a 6-inch thickness, but coverage varies with compaction and layer thickness. For accurate estimation, calculate volume by length × breadth × thickness, then convert to cubic meters and match with the density of jalli 20mm provided by your supplier.
