LIQUID LIMIT DEVICE (MOTORISED) AZA0854

LIQUID LIMIT DEVICE WITH COUNTER AZA0853

The AZA0853 Liquid Limit Device with Counter from AZALAB is a precision-engineered instrument used for determining the liquid limit of soils in accordance with the Casagrande method. This test is a fundamental component of soil classification and geotechnical investigation, providing critical insight into the plasticity, compressibility, and shear strength of fine-grained soils.

Designed for reliable, repeatable, and standardized testing, the AZA0853 is widely used in geotechnical laboratories, civil engineering departments, construction quality control labs, and academic institutions.

Principle of Liquid Limit Test (Casagrande Method)

The liquid limit is defined as the water content at which soil transitions from a plastic state to a liquid state. In practice, it is determined as the moisture content at which a standard groove cut in the soil sample closes over a length of 12.5 mm under 25 blows of the liquid limit apparatus.

The AZA0853 consists of a polished brass cup mounted on an adjustable bracket. The cup is repeatedly raised and dropped from a fixed height of 1 cm onto a hard rubber base by means of a manually operated cam mechanism. A built-in mechanical counter accurately records the number of blows, ensuring compliance with testing standards and reducing operator error.

    MOTORISED SAND EQUIVALENT SHAKER AZA0861

    The AZA0861 Motorised Sand Equivalent Shaker is a precision-engineered laboratory instrument designed to automate the agitation phase of the Sand Equivalent Test. It ensures uniform, repeatable shaking in full compliance with ASTM D2419, AASHTO T176, and IS 2720 (Part 37), eliminating operator variability associated with manual shaking. This shaker is an essential accessory for soil, aggregate, and construction material testing laboratories where accurate assessment of sand cleanliness and clay-like fines is critical.
    Purpose & Function The Sand Equivalent Test evaluates the relative proportion of sand versus clay-sized or plastic fines in fine aggregates. During testing, the sample and calcium chloride solution must be agitated for a defined stroke length and rate. The AZA0861 automates this process using a controlled reciprocating motion, delivering consistent agitation that improves repeatability, reduces operator fatigue, and enhances overall test reliability.

    PARTICLE SIZE SEDIMENTATION (HYDROMETER METHOD) AZA0857

    AZA0857 – Particle Size Sedimentation Apparatus (Hydrometer Method) The AZA0857 Particle Size Sedimentation Apparatus (Hydrometer Method) from AZA Lab is designed for determining the particle size distribution of fine-grained soils, particularly silts and clays smaller than 75 microns. This method is widely adopted in soil mechanics, geotechnical engineering, civil construction quality control, and academic laboratories where accurate characterization of cohesive soils is essential. The hydrometer method is based on the sedimentation principle governed by Stokes’ Law, measuring changes in the density of a soil–water suspension over time. By recording hydrometer readings at defined intervals, the percentage of soil particles remaining in suspension is calculated, enabling precise determination of grain size distribution for fine soils beyond the practical limits of sieve analysis.

    SAND EQUIVALENT TEST SET AZA0859

    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.
