Organic Impurities Test Set with Sodium Hydroxide Pellets

Comprehensive Organic Impurities Test Set with Sodium Hydroxide Pellets

Ensure the integrity and performance of your concrete and construction materials with our Organic Impurities Test Set. This essential kit provides a straightforward, widely-adopted method for detecting deleterious organic materials in fine aggregates. Organic impurities, if present in aggregates, can significantly hinder cement hydration, delay setting times, and ultimately compromise the strength and durability of concrete structures. Identifying these contaminants early is crucial for maintaining construction quality and preventing costly failures.

How it Works: The testing process is simple yet effective. Aggregate samples are mixed with a 3% sodium hydroxide (NaOH) solution in specially designed, graduated colorless glass bottles. After a crucial 24-hour standing period, the color of the supernatant liquid is compared against a circular Color Reference Disc. If the liquid's color is darker than the standard reference, it indicates the probable presence of harmful organic compounds. This result necessitates further investigation or rejection of the aggregate before use, safeguarding your project's longevity.

Complete Set Contents: Our comprehensive set is meticulously assembled to equip you for immediate testing:

• Six 8oz (240mL) Graduated Impurities Test Bottles with Lids: Durable, clear glass bottles featuring both ounce and milliliter graduations for precise measurements. Each comes with a watertight screw-on cap to prevent spillage and ensure sample integrity during the 24-hour standing period.
• 1lb (454g) of High-Quality Sodium Hydroxide (NaOH) Pellets: This generous supply of pellets is sufficient to prepare a 3% sodium hydroxide solution for over 150 individual tests, offering long-lasting value and convenience. For applications requiring the highest level of purity and strict adherence to specific standards, Reagent Grade Sodium Hydroxide Pellets are available for separate purchase.
• Circular Color Reference Disc with Five Reference Colors: Designed for easy and accurate visual comparison, this disc provides a clear standard for assessing the presence and concentration of organic impurities.

Key Features & Benefits:

• Meets Industry Standards: Fully compliant with AASHTO T21 and ASTM C 40/40M, ensuring your tests meet recognized quality and safety benchmarks.
• Essential for Quality Control: A critical tool for quality assurance in concrete production, helping to prevent material defects caused by organic contaminants.
• User-Friendly Design: Simple procedure and clear components make the test accessible for technicians of all experience levels.
• Versatile Availability: The set can be ordered with or without sodium hydroxide pellets, catering to regions with specific shipping restrictions on chemical compounds.
• Individual Component Purchase: All elements of the set, including additional bottles or reference discs, can be acquired separately as needed for replenishment or expansion.
