Aggregates Testing

CIVILTECH QUALITY CONTROL LAB PRIVATE LIMITED provides comprehensive testing of both Coarse Aggregates and Fine Aggregates to ensure compliance with Indian Standard (IS) codes. Aggregates are a vital component of concrete, bitumen, and road works. Proper testing ensures they meet quality standards for strength, durability, and performance in all construction applications.

Services

Our aggregate testing services include:

Sieve Analysis / Grading Test: Determines particle size distribution for proper mix design.
Specific Gravity & Water Absorption: Helps predict concrete workability and durability.
Aggregate Crushing Value (ACV) & Aggregate Impact Value (AIV): Measures resistance to crushing and impact loads.
Los Angeles Abrasion Test (LAA): Determines wear resistance of aggregates in pavements and roads.
Flakiness & Elongation Index: Evaluates aggregate shape for strength and workability.
Material Finer than 75µ: Checks fine content for mix quality control.
Organic Impurities: Detects harmful substances affecting concrete performance.
Soundness Loss Test: Evaluates durability under weathering and chemical attack.
Petrographic Test & Potential Alkali Silica Reactivity (ASR) Test: Ensures long-term concrete stability.

Importance of Aggregates Testing

Aggregates form the bulk of concrete and asphalt (70-75% by volume). High-quality aggregates ensure strength, durability, and consistency of construction materials. Proper testing allows engineers and contractors to:

Design stronger and long-lasting concrete and bitumen mixes.
Prevent premature failure of roads, pavements, and structures.
Ensure compliance with Indian Standard (IS) codes.
Optimize material usage and reduce project costs.
Maintain construction quality and safety for infrastructure projects.

Laboratory & Field Testing

Testing is conducted both in the laboratory and on-site to provide complete reliability. Laboratory tests assess physical and mechanical properties, while field tests ensure performance under actual construction conditions. This combination guarantees accurate, actionable results for all projects.
