ASTM C470
Full Name
ASTM C470 – Standard Specification for Molds for Forming Concrete Test Cylinders Vertically
Scope
ASTM C470 provides specifications for molds used to create cylindrical concrete specimens for testing purposes. This standard applies to both single-use and reusable molds and specifies their design, materials, dimensions, and testing requirements.
Key aspects covered by ASTM C470 include:
- Molds types: it covers both reusable molds (intended for multiple uses) and single-use molds (designed for one-time use).
- Material requirements: molds should be made of materials that do not react with concrete containing portland or other hydraulic cements and are watertight.
- Dimensions and tolerances: the standard specifies the required dimensions for the molds, including the inside height and diameter, as well as tolerances for variations.
- Construction: molds should be designed to be strong and durable, capable of withstanding use without tearing, crushing, or deforming.
- Testing: it details the tests that need to be conducted to ensure the molds’ compliance with the standard, such as water leakage tests.
The primary purpose of ASTM C470 is to ensure the consistency and reliability of concrete testing by standardizing the molds used to create the test specimens. By adhering to this standard, laboratories and construction professionals can ensure the quality and comparability of concrete test results.
