The AZA0921 Pocket Vane Shear Apparatus is a compact, field-ready geotechnical instrument designed for the rapid determination of undrained shear strength of cohesive soils. It enables engineers, geologists, and field technicians to obtain immediate strength data directly at site, avoiding delays and sample disturbance associated with laboratory testing.

Lightweight and mechanically operated, AZA0921 is especially suited for preliminary site investigations, construction quality checks, slope stability assessments, and quick decision-making in remote locations.

The AZA0904 Pore Pressure Apparatus from Azalab is a precision laboratory instrument designed for accurate measurement of pore water pressure in saturated soil specimens during advanced geotechnical testing. It is an essential accessory for Consolidated Undrained (CU) and Consolidated Drained (CD) triaxial shear tests, where correct interpretation of effective stress and soil stability depends directly on reliable pore pressure data.

Engineered for seamless integration with triaxial cells, the AZA0904 enables real-time monitoring of pore pressure generation and dissipation as axial and confining loads are applied. Its rugged construction, calibrated pressure gauge, and leak-proof valve system ensure dependable performance in routine laboratory testing as well as research-grade applications.

The AZA0883 Pycnometer Apparatus from Azalab is a precision laboratory instrument designed for determining the specific gravity (particle density) of soils and aggregates smaller than 10 mm, including clay, sand, and fine gravel. Manufactured in compliance with BS 812, this apparatus delivers accurate, repeatable, and standards-compliant results essential for civil engineering, geotechnical investigations, and construction material testing.

The pycnometer method is widely recognized for its simplicity, reliability, and suitability across a broad range of fine-grained materials used in concrete mix design, pavement construction, and soil characterization.

The AZA0874 Rapid Moisture Meter from Azalab is a compact, reliable, and field-proven instrument designed for quick determination of moisture content in soils, aggregates, sand, and other granular or fine materials. It is especially suited for on-site quality control in civil engineering, road construction, earthwork compaction, and geotechnical investigations, where timely moisture data is critical for effective decision-making.

Based on the well-established calcium carbide gas pressure method, the AZA0874 delivers accurate results within minutes, eliminating delays associated with laboratory oven-drying methods. Its portable, self-contained design makes it ideal for use at remote and demanding job sites.

The AZA0881 Sand Density Cone Apparatus from Azalab is a precision field-testing solution for determining the in-situ density (dry unit weight) of soils using the Sand Density Cone Method. It is widely used by civil engineers, geotechnical consultants, and construction quality teams to verify soil compaction directly at site conditions, providing a realistic and reliable assessment compared to laboratory-based methods on disturbed samples.

This apparatus is essential for earthworks, road construction, pavement layers, embankments, and foundation backfills, where achieving and confirming specified compaction levels is critical to long-term structural performance and safety.

The AZA0859 Sand Equivalent Test Set from AZA Lab is a standardized laboratory and field testing apparatus used to determine the relative proportion of sand versus clay-like or plastic fines in fine aggregates and granular soils. This test is critical in construction quality control where aggregate cleanliness directly affects the performance of asphalt pavements, concrete mixes, and base course layers. The test set conforms to ASTM D2419, IS 2720 (Part 37), and AASHTO T176, ensuring accurate, repeatable, and specification-compliant results. The Sand Equivalent Value (SEV) provides a simple numerical indication of aggregate quality by comparing the height of settled sand to the height of clay suspension after sedimentation. Working Principle A prepared fine aggregate sample is placed in a graduated cylinder and mixed with a standard calcium chloride-based solution. After agitation and a controlled settling period, heavier sand particles settle at the bottom while lighter clay and silt particles remain in suspension. The Sand Equivalent Value (SEV) is calculated as: SEV = (Height of Sand / Height of Clay Suspension) × 100 Higher SEV values indicate cleaner aggregates with lower clay contamination, which are preferred for structural and pavement applications.
