ASTM C513
Full Name
ASTM C513 – Standard Test Method for Obtaining and Testing Specimens of Hardened Lightweight Insulating Concrete for Compressive Strength
Scope
ASTM C513 details the procedure for obtaining, preparing, and testing specimens of hardened lightweight insulating concrete to determine their compressive strength. The concrete in question has an oven-dry density not exceeding 800 kg/m³ (50 lb/ft³). This standard is applicable to both concrete made with lightweight aggregate (conforming to ASTM C332) and concrete made with preformed foam (conforming to ASTM C869).
Key points:
- Purpose: the main purpose of this test method is to determine the compressive strength of hardened lightweight insulating concrete specimens taken from the field or existing structures. This data can be used for various purposes, such as:
- Verifying compliance with specifications.
- Assessing the strength properties of existing construction.
- Evaluating the quality of the concrete.
- Specimen types: the test method covers both drilled cores and specimens sawed from existing construction.
- Preparation: it outlines the procedures for preparing the specimens for testing, including end surface preparation and capping.
- Testing: it details the testing procedure, which involves applying a compressive load to the specimen until failure occurs.
- Calculation: it provides the formula for calculating the compressive strength of the specimen based on the maximum load and cross-sectional area.
Limitations:
- This test method is specifically for lightweight insulating concrete and may not be suitable for other types of concrete.
- The results obtained from this test method may not be representative of the entire structure’s strength due to variations in concrete properties throughout the structure.
