Product Overview
Our 3x6in Concrete Sample Cylinders are the essential tool for anyone in the construction industry. These cylinders are for testing the compressive strength of concrete. Compact size for when space is limited or smaller samples are required. Each cylinder is one piece for uniformity across all samples. Smooth non-absorbent surface for a moisture barrier for accurate test results. Concrete cylinders are environment friendly so they can be used in any testing environment.
3x6in Concrete Sample Cylinders Introduction
Concrete sample cylinders are the backbone of the construction industry for testing concrete strength. The 3x6in concrete sample cylinder is a smaller version of the 6x12in cylinder, perfect for testing smaller concrete samples. This size is great for when space is limited or smaller samples are required. Despite the smaller size these cylinders have the same accuracy and reliability as the larger ones so your concrete meets the required strength standards.
3x6in Concrete Sample Concrete Cylinders Product Description
Concrete test cylinder molds are the tools to create cylindrical concrete specimens astm that represent a composite sample taken from a construction site. These cylinder molds are made from high quality plastic, steel or other rigid materials to hold fresh concrete while it cures. The process of molding concrete cylinders must be done precisely to avoid air pockets or inconsistencies that can affect the test results. Available in various sizes including 4in diameter x 8in height or 6in x 12in these cylinder molds meet ASTM C31 and project specifications for consistent and repeatable results. Standard cured cylinders are required to verify the concrete mix meets project specifications.
Curing Cylindrical Concrete Specimens ASTM
Curing concrete test specimens is a critical step in the testing process as it allows the concrete to develop the strength and durability designed. Proper curing is maintaining the required moisture and temperature conditions to prevent moisture loss which can weaken the concrete. According to ASTM C31 there are two types of curing: initial curing and final curing. Initial curing is 24 to 48 hours where the test cylinders are kept in conditions that minimize moisture loss and temperature fluctuations. Final curing is placing the concrete cylinders in a controlled environment such as a moist room or water storage tank to maintain consistent moisture and temperature conditions so the concrete can reach its designed strength. Field cured cylinders on the other hand are kept in the same environment as the concrete structure and are required to determine if construction can proceed.
Concrete Cylinder Molds and Molding
Concrete cylinder molds are required for forming concrete test cylinders. These molds that are forming concrete test cylinders are designed to meet ASTM C470, C31, C192, AASHTO M 205, R 39 and T 23 test standards. Available in 3x6in, 4x8in and 6x12in sizes these molds are made from durable materials like plastic, steel and cast iron. The high quality of these molds ensures they can withstand the construction process and provide a reliable way to create cylindrical concrete specimens for testing.
Handling and Storage of Concrete Test Cylinders
Proper handling and storage of concrete test cylinders is important to prevent damage and get accurate test results. During transport the concrete cylinders must be cushioned against jarring and protected from freezing and moisture loss. Keeping the cylinders in their cylinder molds during transport provides extra protection. Upon arrival at the testing lab the concrete cylinders should be logged into the lab’s concrete sample registry, removed from their cylinder molds and placed in the final curing environment. Leaving the cylinders in the open air can cause moisture loss and physical damage which can affect the test results.
Acceptance Testing and Quality Control for 3x6in Concrete Sample Cylinders
Concrete test cylinders are used in acceptance testing and quality control to verify the ready mixed concrete meets the project’s strength requirements. These cylinders are tested at specified intervals, usually 7 days, 28 days and sometimes beyond depending on the project specifications. The test cylinder is placed in a compression testing machine where pressure is applied until the sample breaks and measures the concrete’s strength. The results of these tests will determine if the structural concrete meets the design strength for the specific structural work being done. Acceptance testing and quality control is a critical step to ensure the quality and reliability of concrete used in construction projects.
Applications and Benefits
Concrete sample cylinders are used in many applications, quality control, acceptance testing and research and development. The benefits are:
-
Accurate Compressive Strength: Ensures the concrete meets the required strength specs.
-
Reliable Results: Provides consistent and repeatable results for quality control.
-
Cost Effective: A cost efficient way to test concrete samples.
-
Easy to Use: Easy to handle and transport, makes testing simple.
-
Versatile: Can be used in many testing environments and conditions.
Concrete sample cylinders are a must have in the construction industry to get accurate and reliable results for quality control and acceptance testing. Their small size and versatility makes them perfect for testing concrete in tight spaces or when a smaller sample is required to ensure your concrete meets the highest strength and durability standards.
Conclusion 3x6in Concrete Sample Cylinders
Concrete test cylinders are the tool for quality control and acceptance testing of structural concrete. They ensure the concrete mix used in construction meets the project specs for strength and durability, when they are forming concrete test cylinders correctly. By following the guidelines for curing, molding and testing in ASTM C31 construction professionals can be sure the concrete used in their projects will perform as expected. Proper handling and storage of concrete test cylinders and rigorous acceptance testing and quality control is part of the testing process. These practices will ensure the quality and reliability of concrete used in construction and the safety and longevity of the structure.
