Paragon 3x6-inch Concrete Sample Cylinders (Case of 80)

3x6in Concrete Sample Cylinders (Case of 80)

Ensure the quality and strength of your concrete with our 3x6in (76 x 152mm) Concrete Test Cylinder Molds. Sold in a case of 80, these single-piece, non-absorbent plastic units provide consistent shape and precise dimensional tolerance for every sample. Engineered for accuracy and durability, they are the industry standard for creating concrete test specimens to determine compressive strength in accordance with ASTM C31, C39, and other key standards.

Ideal for both field and lab use, these molds are the go-to choice for quality control managers, civil engineers, and construction professionals who demand reliable results.

Key Features & Specifications

Dimensions and Specs:

• Cylinder Size: 3in (76mm) diameter x 6in (152mm) height
• Weight (per case): 45 lbs (20.4 kg)
• Packaging: 80 cylinders per case
• Pallet Quantity: 30 cases per pallet
• Lid Style: Attached domed plastic lid for a secure seal

Product Features:

• Uniform Design: Each mold is a single, seamless piece of injected plastic, ensuring uniformity and consistency across all your samples.
• Non-Absorbent Surface: The smooth molded plastic acts as a moisture barrier, preventing water loss from the sample and ensuring the concrete cures properly for accurate strength testing.
• Easy Stripping: The smooth interior surface facilitates quick and effortless removal of cured specimens, improving testing efficiency.
• Secure & Protective Lid: The attached domed lid seals tightly to protect the sample from contamination, damage, and moisture loss during transport and initial curing. The flat top surface allows for easy labeling and stable stacking.
• Climate Resistant: Made from durable, multi-layered plastic, these molds are weather-resistant and have no expiration date, allowing for long-term storage.
• Made in the USA: Proudly manufactured in the USA, our molds meet the highest quality standards of the American construction and testing industries.

Compliance with Industry Standards

Our 3x6in plastic cylinder molds are designed to meet a comprehensive range of testing standards. Following the procedures outlined in these standards is critical for producing valid, repeatable results and ensuring project compliance.

Supported Test Methods:

• AASHTO: M205, T22, T23, T126, T198
• ASTM: C31 (Standard Practice for Making and Curing Concrete Test Specimens in the Field), C39 (Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens), C192, C470, C496

The Importance of Proper Curing and Handling

Accurate strength test results begin the moment a sample is taken. Adhering to standard procedures for curing, handling, and transportation is essential to avoid low-strength readings, which can lead to costly project delays.

• Initial Curing (ASTM C31): For the first 24 to 48 hours, cylinders must be stored in conditions that minimize moisture loss and maintain a specified temperature range. Our molds with secure lids are designed to support this critical phase.
• Final Curing: After initial curing, specimens are moved to a controlled environment, such as a moist room or water storage tank, to achieve their full design strength.
• Handling & Transportation: Cylinders must be protected from jarring, extreme temperatures, and moisture loss. Transport time from the jobsite to the lab should not exceed 4 hours to maintain sample integrity.

Recommended Accessories for a Complete Testing Workflow

Enhance your testing process with our range of compatible tools and accessories:

• Tamping Rods: Features a hemispherical tip for proper consolidation of concrete in the mold.
• Concrete Strike-Off Bar: Used for removing excess material to create a level specimen surface.
• Easy Stripping Tools: Quickly and cleanly remove cured samples from molds with our Screw-Driver style stripping tool.
• Rubber Mallet: A 2.25in hard rubber face mallet for various consolidation and de-molding tasks.
• Cooling & Curing Devices: We offer thermostatically controlled water tanks and other solutions to maintain proper curing temperatures.

Why Choose Our 3x6in Concrete Test Cylinders?

Whether you're in construction, materials engineering, or academia, the integrity of your structures depends on accurate data. Our 3x6in test cylinders are the essential tool for verifying that ready-mixed concrete meets project specifications.

The 3x6in size is ideal for projects where smaller samples are specified, or when job site space is limited. While offering the same precision as larger 4x8in or 6x12in molds, this compact size is easier to handle and transport.

With 80 cylinders per case, you’ll be well-equipped for extensive project testing. Trust our molds to provide the consistent, reliable results needed to ensure the safety, quality, and longevity of your structural work.
