SHAPE INDEX CALIPER AZA0974
The AZA0974 Shape Index Caliper is a precision hand-held measuring instrument designed to evaluate the shape index of coarse aggregates by measuring their flakiness and elongation values. It is an essential tool in construction material testing, helping laboratories and site engineers ensure that aggregates meet dimensional and performance standards as per IS 2386 (Part I).
Key Features
-
Evaluates shape index of coarse aggregates
-
Measures both flakiness and elongation characteristics
-
Durable stainless steel / hardened steel construction
-
Precision engraved measuring scale
-
Ergonomic, easy-to-handle manual design
-
Suitable for laboratory and on-site field use
-
Fully compliant with IS 2386 (Part I)
Description
Importance of Shape Index Testing
The shape index determines whether aggregate particles fall within acceptable geometric limits. Excessively flaky or elongated particles can:
-
Reduce packing density
-
Increase voids
-
Decrease compaction quality
-
Lower strength and durability of concrete and asphalt
By using AZA0974, engineers can quickly verify aggregate quality before use in structural and pavement works.
Working Principle
The AZA0974 operates through a dual-arm caliper mechanism with an engraved scale:
-
Measures the least dimension to evaluate flakiness (when thickness < 0.6 × mean size)
-
Measures the largest dimension to evaluate elongation (when length > 1.8 × mean size)
It requires no power, no complex calibration, and delivers instant results.
Applications
-
Road and highway construction projects
-
Bridge and infrastructure works
-
Concrete and asphalt mix design laboratories
-
Aggregate manufacturing and crushing plants
-
Academic and research institutions
