Hand Mixer Testing

A sample of cement, aggregates & water is manually mixed to check workability, consistency & bonding.

Ensures compatibility before batching

Sieve Analysis

Aggregates & M-Sand are passed through graded sieves to ensure proper particle size distribution.

Guarantees strong packing & smooth finish

Slump Cone Test

Fresh concrete is tested to measure workability & water control for easy placement at site.

Ensures proper water–cement ratio

Compression Strength Test

Concrete cubes are tested under load to confirm grade strength like M20 / M25 / M30 / M40.

Confirms grade performance

Flexural Strength Test

Concrete beams are loaded until bending failure to measure tensile & slab load resistance.

Shows slab & bending resistance

Rebound Hammer Test

Non-destructive test for surface hardness without damaging the concrete structure.

Strength check without damage

Weighing & Proportioning

All raw materials are weighed using digital weighers for precise mix ratios.

Maintains grade consistency

Specific Gravity Test

Determines density & water absorption of aggregates to prevent cracking or shrinkage.

Avoids moisture-related failures
