About Alkali Aggregate Reaction Bath

Specification:

An alkali aggregate reaction (AAR) bath is a lab device that maintains specimens in a solution (often

) at a controlled temperature, typically between ambient and

100C100 raised to the composed with power cap C

100

. Key specifications include stainless steel construction, digital temperature control with accuracy of about

1C1 raised to the composed with power cap C

, a capacity for multiple specimens, and the ability to hold samples that are

Purpose: Used for accelerated testing of the potential alkali reactivity of cement-aggregate combinations.

Advanced Temperature Control and Safety Features

Equipped with a digital PID temperature controller, this bath ensures highly accurate monitoring and adjustment, with a temperature range from 0C to 80C and a fine resolution of 0.1C. Over-temperature protection and a leak-proof construction ensure user and sample safety during continuous testing, while high-density insulation preserves thermal stability for reliable results.

Practical Design for Efficient Laboratory Use

Engineered for convenience, the stainless steel chamber is corrosion-resistant, and the transparent borosilicate lid allows unobstructed observation of up to six specimens simultaneously. The magnetic pump offers uninterrupted water circulation, vital for even temperature distribution, and the device's compact floor-standing structure fits seamlessly into laboratory environments.

Comprehensive Compliance and Support

This equipment strictly conforms to IS: 2386 (Part 7) and ASTM C1260 standards, essential for credible aggregate reactivity studies. Delivered with specimen holders, a detailed instruction manual, and optional on-site installation, users receive strong operational guidance and service support. Available through various dealer networks in India, it caters to suppliers, manufacturers, and research institutions.

FAQ's of Alkali Aggregate Reaction Bath:

Q: How does the Alkali Aggregate Reaction Bath maintain precise temperature control?

A: The bath uses a digital PID temperature controller that keeps the water temperature accurate within 1C, covering a range from ambient up to 80C. Immediate response to changes ensures stable and consistent conditions throughout testing sessions.

Q: What is the process for conducting alkali aggregate reactivity tests using this bath?

A: Specimens are held in supplied holders and immersed in the circulating water bath. The digital controller sets the required temperature, while the transparent lid aids specimen observation. The bath provides even heat distribution, essential for conducting standardized tests as per IS: 2386 (Part 7) and ASTM C1260.

Q: When should the bath's over-temperature protection be used?

A: The over-temperature protection is automatically activated when the bath detects temperatures exceeding preset safety thresholds, safeguarding specimens, users, and equipment during extended or unattended operations.

Q: Where is this bath typically installed and used?

A: It is designed for laboratory environments, particularly in research institutions, concrete testing facilities, and construction material testing labs. Its floor-standing compact structure allows easy integration into most laboratory layouts.

Q: What are the main benefits of the high-density insulation and stainless steel construction?

A: High-density chamber insulation preserves thermal stability and improves energy efficiency during tests. The stainless steel chamber resists corrosion and supports long-term durability, making the equipment both reliable and low-maintenance.

Q: How many specimens can be tested at one time and what are the size limitations?

A: The bath can accommodate up to six specimens at once, each with a maximum diameter of 75 mm and length of 450 mm, providing sufficient capacity for batch testing in laboratory workflows.
