Alkali Silica Reactivity (ASR) Detection Kit

ASR Detect Kit: Rapid Alkali Silica Reactivity Testing for Hardened Concrete

The ASR Detect Kit provides a fast, field-friendly method for identifying Alkali Silica Reactivity (ASR) in hardened concrete. Developed and patented by Los Alamos National Laboratories, this innovative kit allows field personnel with minimal training to accurately assess ASR simply by testing a freshly-broken concrete surface. This significantly reduces the need for expensive and time-consuming petrographic analyses in diagnosing concrete deterioration.

How it Works:

The kit utilizes two specialized reagents that deliver clear color indications for both early and advanced stages of ASR. The process is straightforward:

1. Surface Preparation: Begin with a clean, freshly-broken surface of the concrete sample.
2. Reagent 1 Application: Apply the first reagent to the concrete surface. If initial stages of ASR degradation are present, a distinct bright yellow precipitate will appear.
3. Rinsing: Rinse the surface thoroughly with distilled water.
4. Reagent 2 Application: Apply the second reagent. If the degradation is more advanced, a bright pink stain will develop. Concrete unaffected by ASR will show no color change.

The entire test takes less than five minutes to complete, providing immediate results. Furthermore, the reaction stains are permanent, eliminating the need for retesting and allowing for clear documentation.

Key Features & Benefits:

• Rapid & Simple Detection: Quickly identify ASR in hardened concrete, saving time and resources.
• User-Friendly: Requires minimal training for field personnel, making it accessible for a wide range of users.
• Clear Visual Indicators: Distinguish between early (yellow) and advanced (pink) stages of ASR degradation with distinct color changes.
• Cost-Effective: Significantly reduces reliance on costly petrographic lab analyses.
