GILLMORE NEEDLE APPARATUS AZA0790

Description

Gillmore Needle Apparatus is a precision testing device used to determine the initial and final setting times of cement and gypsum-based materials. The model AZA0790, available from Azalab, is designed for reliable and standardized use in laboratories, particularly in civil engineering and materials testing applications.

Product Overview:

The Gillmore Needle Apparatus AZA0790 follows the ASTM C266 standard method, which specifies the procedures for measuring the setting times of hydraulic cement. This apparatus consists of two weighted needles mounted on a support frame, each designed to evaluate either the initial set or the final set.

• The initial setting needle has a 1/4 lb (113.4 g) weight with a 1/12 inch (2.12 mm) diameter tip.
• The final setting needle has a 1 lb (453.6 g) weight with a 1/24 inch (1.06 mm) diameter tip.

These needles are suspended vertically from a sliding collar, enabling them to freely fall onto the surface of the cement paste placed in a mold. This process helps determine the resistance offered by the cement paste, indicating the progression of hydration and setting.

Build and Materials:

Manufactured with corrosion-resistant brass and stainless steel, the AZA0790 is built for long-term use in demanding lab environments. The polished needle shafts and weights ensure precise penetration and accurate readings. The base frame is sturdy and balanced, allowing easy vertical positioning without compromising the setup.

Applications:

This apparatus is widely used in:

• Cement testing laboratories
• Educational institutions (civil engineering labs)
• R&D departments in the construction industry
• Quality control in cement manufacturing units

How It Works:

1. A cement paste is placed in a standard mold.
2. The needle is released from a specific height.
3. Observations are taken at fixed time intervals.
4. Initial set is identified when the initial needle fails to penetrate.
5. Final set is noted when the final needle no longer makes an impression.

Compliance:

The Gillmore Needle Apparatus from Azalab is designed to meet international standards. Its accuracy and repeatability make it an essential part of a materials testing lab’s equipment.
