Test Methods & Laboratory Work Orders
ASTM / BS / AASHTO standardized calculation templates, apparatus calibration metadata, and active technician assignments.
Direct Shear Test of Soils under Consolidated Drained Conditions
Determines consolidated drained shear strength parameters: internal friction angle (φ) and apparent cohesion (c) under multi-stage normal stresses.
Standard Proctor Compaction Test (Laboratory Compaction Characteristics)
Determines the relationship between molding water content and dry unit weight of soils to obtain Maximum Dry Density (MDD) and Optimum Moisture Content (OMC).
Sieve Analysis of Fine and Coarse Aggregates
Determines particle size distribution of fine and coarse aggregates by sieving, calculating gradation curve, D10, D30, D60, and Fineness Modulus.
Liquid Limit, Plastic Limit, and Plasticity Index of Soils (Atterberg)
Determines liquid limit, plastic limit, and plasticity index of soils, classifying soils on the Casagrande Plasticity Chart (A-line USCS classification).
Compressive Strength of Cylindrical Concrete Specimens
Measures compressive strength of 150×300 mm or 100×200 mm concrete test cylinders at 7, 14, and 28 days with automatic fracture pattern recording.
One-Dimensional Consolidation Properties of Soils (Oedometer)
Determines rate and magnitude of consolidation of soil when restrained laterally and drained axially (Cc, av, mv, and e–log P curve).
Mohr Circle Stress & Failure Envelope Analysis
Parametric circle stress solver, principal stresses (σ1, σ3), and tangent Mohr-Coulomb failure envelope (c, φ).
