Concrete Cylinder Mould, Plastic

Ø150x300 mm Heavy Duty Plastic Cylinder Mould, Ø100x200 mm Plastic Splitting Cylinder Mould, Ø150x 300mm ABS Plastic Splitting Cylinder Mould.

Concrete Plastic Cylinder Mould is used to create standardized concrete Cylinder samples for testing purposes. These moulds are made from a combination of plastic materials, for easy use and carried on-site or in the testing lab. The purpose of a Concrete Plastic Cylinder Mould is to accurately shape and contain freshly mixed concrete samples in the form of cylinders. These cylinders are then allowed to cure and harden under controlled conditions, usually in a laboratory setting or on-site, to determine the compressive strength of the concrete.

We provide a wide range of high-quality concrete specimen moulds such as cylinders & beams of different kinds of sizes. Mould materials such as HEAVY DUTY ABS PLASTIC, HIGH-DENSITY PLASTIC, CAST IRON & MILD STEEL are available.

Feature of Concrete Plastic Cylinder Mould

• With a one-piece design and no need for assembly
• Resistant to vibrations, shocks, and wear, they maintain accuracy and shape integrity through multiple tests.
• Suitable for lab or on-site use, making concrete testing convenient and efficient.

Standards

• EN 12390-1: European standard for testing concrete strength, covering procedures for casting, curing, and testing concrete specimens.
• ASTM C39/C192: American standards detailing testing procedures for compressive strength of concrete cylinders (C39) and guidelines for specimen preparation and testing in laboratories (C192).
• AASHTO T23/T126: Standards from the American Association of State Highway and Transportation Officials, specifying procedures for preparing and testing concrete specimens for compressive strength.
• BS 1881:108: British standard outlining methods for making, curing, and testing concrete compressive strength, ensuring consistent testing practices.

Test Procedure of Concrete Plastic Cylinder Mould

1. Preparation of Mould: Ensure the mould is clean and free from any debris or previous residues and check for any damages. Apply a thin layer of mold release agent to facilitate easy removal of cylinders.

2. Mix Design Preparation: Prepare concrete mix as per the desired specifications and proportions. 

3. Cylinder Casting: Fill the mould with freshly mixed concrete in layers, compacting each layer thoroughly to remove air voids. 

4. Curing: Cover the filled mould with a damp cloth or plastic sheet to prevent moisture loss. Allow the concrete to cure undisturbed for the specified duration, typically 24 hours in a controlled environment with regulated temperature and humidity.

5. Demolding: After the curing period, carefully remove the mould from the concrete cylinder. Use a rubber mallet or similar tool to tap around the sides of the mould to loosen it from the concrete. 

6. Initial Measurements: Measure the dimensions (length, width, and height) of the concrete cylinder using a calibrated measuring device such as a caliper or ruler. Record the measurements accurately.

7. Testing: Perform compression testing on the cylinder using a compression testing machine. Record the maximum load applied and the corresponding deformation or strain.

8. Analysis:  Calculate the compressive strength of the concrete cylinder using the maximum load and the cross-sectional area. Compare the obtained strength with the specified requirements or standards. 

9. Reporting: Document the test results, including dimensions, compressive strength, and any relevant observations. Report any deviations from expected performance and provide recommendations for improvement if necessary.

10. Cleanup: Clean the mould thoroughly after use to remove any residual concrete or contaminants. Store the mould in a dry and safe location to prevent damage or deterioration.
