Product Description and Features

Concrete test cylinders are a crucial tool in the construction industry used to determine the strength and durability of concrete in various projects. These cylinders are used for concrete strength testing as per ASTM C31. The purpose of test cylinder molds is to create standardized specimens that represent the concrete strength of the composite sample taken from the construction site. The selection of the cylinder mold depends on the maximum size of the aggregate in the concrete mix as per ASTM standards. The diameter of the cylinder mold should be at least three times the nominal maximum size of the coarse aggregate to ensure accurate strength testing. Made from smooth molded plastic, steel or other rigid materials, these molds are designed to hold fresh concrete while it cures, to get consistent and reliable test results. Forming concrete test cylinders involves pouring into the cylinder mold in layers, with each layer being properly filled and consolidated to remove air pockets, as per ASTM procedures for accurate and representative specimens.

Our concrete test cylinders are designed to meet the exacting requirements of ASTM C31 to form concrete test cylinders. The design of the cylinders makes them easy to handle during transportation and testing. Available in various sizes including 6 inches by 12 inches or 4 inches diameter by 8 inches height, these cylinders cater to different project needs. Proper molding of concrete cylinders is critical to avoid air pockets or inconsistencies that can affect the test results. With our high quality molds you can ensure your concrete cylinders are formed with precision and integrity. The smooth molded plastic design allows for easy stripping of the concrete specimens after curing. The entire quantity of test cylinders required for your project can be accommodated with our case and pallet options.

Handling and Storage

To ensure accuracy and reliability of test results, concrete samples including test cylinders should be handled and stored with care. These cylinders should be kept in a dry, weather resistant location, away from direct sunlight and extreme temperatures. Proper storage helps prevent damage and minimizes job site storage problems so your test cylinders remain in optimal condition for testing.

During the initial curing process, wet burlap can be used to cover cylinders to prevent moisture loss and maintain a stable curing environment.

Field cured cylinders are stored on site to reflect actual in-place curing conditions, as opposed to standard cured cylinders which are stored in controlled laboratory environments.

Common Uses for Concrete Test Cylinders

Concrete test cylinders are a crucial tool in the construction industry, particularly in quality control and acceptance testing of structural concrete. Concrete test cylinders are used to test the compressive strength of ready mixed concrete in construction projects. They are used to test the strength and durability in various applications including building foundations, bridges and highways. Also used for unit weight tests and other tests to verify the concrete mix meets the project specifications. The same equipment is used for weight tests and other tests such as slump and air content tests. By using these cylinders construction professionals can ensure their structures are built to last and meet all requirements. Only cylinder sizes and types permitted by ASTM specification should be used for compliance. Standard curing in a laboratory environment is required for accurate results and compliance with specification requirements.

The standard test method is important in concrete testing, to comply with established procedures like ASTM C39 and ASTM C31 to ensure the quality, strength and safety of concrete structures.

4x8 In Concrete Test Cylinder Molds are a gray, single piece, non-absorbent, injected plastic unit for a consistent shape and dimensional tolerance. The 4x8in Concrete Test Cylinder Molds are climate resistant and have an unlimited shelf life. Initial curing is important for concrete cylinders, as maintaining moisture and stable temperature conditions during the first 24 to 48 hours is critical to develop the desired strength. You can find these molds and everything else you need for concrete testing at Certified MTP. Browse everything available including a profoscope, concrete thermometer stick, the NR Hammer and more.

Our most popular 4x8 Concrete Test Cylinders come in either 36 per case or 96 per case and can be purchased in either gray or yellow. All of our plastic concrete test cylinders are made from a non-absorbent, single-piece injected plastic mold for a consistent shape and dimensional integrity. These concrete test cylinders are climate resistant and have no expiration. We also offer the 2x4 concrete test cylinders, 3x6 concrete test cylinders, and the 6x12 concrete test cylinders. Not only do we offer concrete test cylinders, but we also carry quality graduated tamping rods and domed lid.
