Comprehensive Aggregate Testing Portfolio
We deploy high-precision digital sieves, crushing machines, and physical testing apparatus to verify particle gradation and mechanical durability.
Fine Aggregate Testing
Evaluating sand quality, silt content, organic impurities, and grading zones to ensure optimal mortar and concrete bonding properties.
Coarse Aggregate Testing
Analyzing crushed stone and gravel properties to verify soundness, shape indices, and load-bearing performance for high-grade concrete.
Sieve Analysis Test
Determining particle size distribution and fineness modulus for both fine and coarse aggregates through standardized mechanical sieve shaking.
Aggregate Impact Value Test
Measuring the resistance of coarse aggregates to sudden dynamic shocks or impact loads to gauge overall structural toughness.
Aggregate Crushing Value Test
Quantifying aggregate resistance under gradually applied compressive loads to determine suitability for heavy-duty pavement and structural applications.
Specific Gravity of Aggregate
Calculating the ratio of aggregate weight to water weight to evaluate material density and porosity for concrete mix design calculations.
Water Absorption Test
Measuring moisture absorption capacity of aggregate pores after soaking to control effective water-cement ratios during batching.
Bulk Density Test
Determining loose and compacted weight per unit volume of aggregate fractions to estimate void ratios and batching container sizes.
Flakiness and Elongation Index Test
Evaluating particle shape uniformity to screen out flaky or elongated stones that could compromise concrete workability and strength.
Sand Testing Laboratory
Our specialized sand testing laboratory handles river sand and manufactured sand (M-Sand) evaluations, checking silt factor and chemical purity.
Uncompromising Precision in Aggregate & Sand Quality Assurance
Aggregates constitute nearly 75% of a concrete mix, making their physical and mechanical properties vital to structural longevity. At Jacob Engineers, our dedicated Sand Testing Laboratory and aggregate divisions execute precise evaluations to eliminate sub-standard materials from your supply chain. Whether performing a routine Sieve Analysis Test for grading control or executing an Aggregate Impact Value Test and Aggregate Crushing Value Test to measure load resilience, our facility delivers uncompromised data.
From screening particle shape variations via the Flakiness and Elongation Index Test to evaluating density and absorption characteristics through the Specific Gravity of Aggregate, Water Absorption Test, and Bulk Density Test, our NABL accredited protocols cover every specification. By thoroughly verifying both Fine Aggregate Testing and Coarse Aggregate Testing parameters, we ensure your structural concrete and pavement sub-bases achieve maximum durability.

Frequently Asked Questions
Technical answers for civil engineers, procurement managers, and quality control specialists.
The sieve analysis test determines the particle size distribution (gradation) of fine and coarse aggregates, ensuring optimal void filling, workability, and cohesive strength in concrete.
These values measure the mechanical strength and resistance of coarse aggregates against sudden shock loads and continuous compressive weight, ensuring pavement and structural durability.
Aggregates absorb water from the mix if dry or contribute excess water if wet. Knowing the water absorption percentage allows engineers to precisely adjust water-cement ratios for target strength.
Flaky or elongated particles reduce workability, increase cement paste requirements, and create planes of weakness that lower the overall structural integrity of concrete.
