Description

Description

Principle of Operation

The AZA0931 operates on the principle of elastic deformation:

  1. A precisely machined alloy steel ring is subjected to a known compressive or tensile load.

  2. The applied force causes a small, proportional elastic deflection of the ring.

  3. This deflection is measured using an integrally mounted dial gauge or electronic transducer.

  4. A unique calibration factor or calibration curve, supplied with each ring, directly correlates deflection to applied force (kN or kgf).

The “Integral” design ensures that the measuring device is permanently mounted within the ring body, providing compactness, robustness, and repeatable accuracy.

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.

SEMI AUTOMATIC CONE PENETROMETER AZA0852

The AZA0852 Semi Automatic Cone Penetrometer from AZALAB is a precision-engineered laboratory instrument used for determining the liquid limit and consistency characteristics of fine-grained soils. Designed to eliminate operator-dependent errors, this semi-automatic model ensures uniform cone release and repeatable penetration results, making it an ideal choice for geotechnical, civil engineering, and construction material testing laboratories. The apparatus conforms to IS 2720 (Part 5) and BS 1377 standards and is widely used for soil classification, foundation assessment, and settlement analysis. Its semi-automatic clutch-based drop mechanism allows the cone to penetrate the soil sample under controlled conditions for a fixed duration of 5 seconds, ensuring consistent and reliable test outcomes.

Principle of Operation

A soil paste prepared at known moisture content is placed in the sample cup. The standardized cone, attached to a calibrated weight, is released using the semi-automatic clutch mechanism, allowing free fall penetration into the soil. After the specified time (typically 5 seconds), the penetration depth is measured using a high-precision dial gauge. The moisture content corresponding to a penetration of 20 mm is considered the liquid limit of the soil, as defined in IS and BS standards.
