Engineered for Excellence

Our 20mm aggregates are designed to meet the highest standards for construction and infrastructure requirements. Featuring a rough, angular form and consistent particle size, these aggregates ensure strong mechanical interlock and enhanced durability in concrete mixes. Each batch undergoes strict quality control, guaranteeing compliance with industry benchmarks and reliable performance on site.

Versatile Applications

These aggregates serve as an essential component in construction, roadwork, and concrete manufacturing. Their optimal fineness modulus (6.5-7) delivers the right balance for mixing, while low silt and moisture content maintain the integrity of the final product. Suitable for projects ranging from residential buildings to expansive highways, they deliver robust, long-lasting results where strength and reliability are crucial.

FAQs of 20mm Aggregates:

Q: How should 20mm aggregates be stored and handled at the construction site?

A: Store 20mm aggregates on a clean, raised surface in a well-drained area to prevent contamination from soil, silt, or moisture. Covering with a waterproof sheet is recommended to limit excess moisture absorption and maintain their 1% moisture content.

Q: What are the benefits of using 20mm aggregates with angular shape and rough surface texture?

A: Angular aggregates with rough surfaces provide superior mechanical interlock and better bonding with cement mortar, resulting in higher concrete strength and durability compared to smooth or rounded aggregates.

Q: Where are these 20mm coarse aggregates typically used?

A: These aggregates are used mainly in concrete manufacturing, road construction, and general civil engineering projects in India. Their high compressive strength and durability make them ideal for structural applications requiring robust, long-term performance.

Q: When should I choose 20mm aggregates over finer sizes?

A: Select 20mm aggregates when you need coarse material ensuring proper load distribution in concrete. Theyre the standard choice for structural members, foundation work, and pavements, providing enhanced mechanical strength and reduced surface shrinkage.

Q: What quality standards do these aggregates meet?

A: Our 20mm aggregates are manufactured in compliance with IS: 383 1970, ensuring all properties like silt content, flakiness index, moisture, and particle size distribution meet the industrys stringent requirements for concrete and construction uses.

Q: How does low porosity and minimal water absorption impact concrete performance?

A: Low porosity (1-2%) and water absorption rates under 2% minimize internal voids and prevent excessive water demand in concrete mixes. This leads to higher density, reduced drying shrinkage, and extended working life of the finished structure.
