DYNAMIC CONE PENETROMETER AZA0872

The AZA0872 Dynamic Cone Penetrometer (DCP) from Azalab is a robust, field-proven instrument designed for rapid in-situ evaluation of soil strength, stiffness, and compaction. It is extensively used by civil engineers, geotechnical consultants, and construction teams for pavement design, quality control, and site investigation works.

The DCP test provides a fast and economical method to assess the strength of subgrades, sub-bases, and granular base course layers, with results that can be directly correlated to California Bearing Ratio (CBR) values. This eliminates the need for time-consuming laboratory testing or undisturbed soil sampling, enabling immediate decision-making at site.

Description

Description

Principle of Operation

The AZA0872 operates on a simple and well-established impact penetration principle. A hardened steel cone attached to a drive rod is driven into the ground by repeatedly dropping a standard weight hammer from a fixed height. The penetration per blow is measured and recorded, providing a direct indication of soil resistance.

By plotting penetration versus depth, a continuous strength profile of the pavement or soil layer is obtained, clearly identifying weak zones, variability, or insufficient compaction.

GRAIN SIZE ANALYSIS (PIPETTE METHOD) AZA0856

The AZA0856 Grain Size Analysis (Pipette Method) Apparatus from AZA Lab is a precision testing setup used for determining the distribution of fine soil particles such as silt and clay. It is widely used in geotechnical engineering, civil construction quality control, soil mechanics research, and academic laboratories, particularly where conventional sieve analysis is ineffective for particles finer than 75 microns. This apparatus is designed for the mechanical analysis of sub-sieve soil particles, expressing quantitatively the proportion by weight of various particle sizes present in a soil sample. The pipette method, based on sedimentation principles and Stokes’ Law, provides accurate and repeatable results for fine-grained soils. The system consists of a sliding vertical panel operated by a precision screw mechanism, allowing an Anderson pipette to be raised or lowered accurately. A sedimentation tube is held securely below the pipette using a laboratory clamp. The depth of immersion is measured using a millimeter-graduated scale mounted alongside the sliding panel. The apparatus is supplied complete with a 10 ml Anderson pipette, a 500 ml glass sedimentation tube, and test form pads, conforming to standard laboratory practices.
