Paragon 4x8-inch Concrete Test Cylinders (36 per Case, Yellow)

4x8 Concrete Test Cylinders (36 per Case, Yellow) – The Standard for Concrete Strength Testing

Ensure the quality and integrity of your concrete with our premium 4x8 Concrete Test Cylinders. As a fundamental tool in the construction industry, these cylinder molds are essential for verifying the compressive strength and durability of fresh concrete, providing the data you need to build with confidence.

Our 4x8 concrete cylinders are the industry standard for creating uniform test specimens. Each mold is a single, non-absorbent piece of injected plastic, ensuring they won’t deform or lose their precise dimensions under job site conditions. The vibrant yellow color enhances visibility on site, improving safety and efficiency during the crucial testing process.

Key Features & Specifications:

• Standardized Dimensions: Each cylinder measures 8 inches (203mm) in height and 4 inches (102mm) in diameter, adhering to the standard 4x8 size required for consistent concrete testing.
• Durable Construction: Made from high-quality, non-absorbent injected plastic, these molds are weather-resistant and built to withstand harsh environmental conditions across the USA. This robust material gives them an unlimited shelf life and allows for multiple reuses without compromising integrity.
• Secure Packaging: Cylinders are shipped in cases of 36, with 30 cases per pallet. Each case includes a tight-fitting domed lid, designed to maintain optimal moisture levels for proper curing and protect specimens during transport and storage.
• Flat Lid Option: For applications requiring a different closure, durable, non-absorbent flat lids are also available. These lids provide excellent protection and ensure specimen integrity.
• Full Compliance: Our molds meet a comprehensive range of industry standards, including AASHTO M205, T22, T23, T126, T198 and ASTM C31, C39, C192, C470, C496. This ensures their suitability for a wide variety of approved concrete testing methods.

Applications:

These cylinders are indispensable for:

• Compressive strength testing of fresh concrete.
• Quality control and assurance programs on construction projects.
• Research and development in material science labs.
• Verifying mix proportions for structures like buildings, bridges, and water storage tanks.

Please Note: Compressive strength data obtained from these standard field-cured cylinders indicates the potential strength of the concrete mix as discharged from the truck, not the in-place strength of the cured structure.

Achieve Accurate Results with Proper Procedure:

1. Sampling: Obtain a representative sample of fresh concrete according to ASTM C172 standards.
2. Molding: Place the concrete in the cylinder mold in layers, rodding each layer with a tamping rod to consolidate the specimen and remove air voids.
3. Curing: For the initial 48 hours, cylinders must be stored in a controlled environment (60-80°F) to ensure proper initial curing. Protect them from direct sunlight, wind, and freezing temperatures.
4. Stripping & Transport: After initial curing, carefully remove the specimen from the mold using a stripping tool. Transport the cured cylinders to a testing laboratory, ensuring they are protected from damage.
5. Testing: A certified lab will perform a compression test by applying a gradual axial load until the cylinder fails. This failure point determines the concrete's compressive strength (psi).
