ASTM C513/C513M − 11 1 Standard Test Method for Obtaining and Testing Specimens of Hardened Lightweight Insulating Concrete for Compressive Strength

Scope of ASTM C513/C513M − 11 1 Standard Test Method for Obtaining and Testing Specimens of Hardened Lightweight Insulating Concrete for Compressive Strength

1.1 This test method covers obtaining, preparing, and testing specimens of hardened, lightweight, insulating

concrete made with either lightweight aggregate conforming to Specification C332 or using preformed foam

made from a foaming agent conforming to Specification C869 and having an ovendry density not exceeding 800

kg/m3 [50 lb/ft3].

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Combining values from the two systems may result in non-conformance with the standard.

Significance and Use of ASTM C513/C513M − 11 1 Standard Test Method for Obtaining and Testing Specimens of Hardened Lightweight Insulating Concrete for Compressive Strength

4.1 This test method is used to determine the compressive strength of hardened lightweight insulating concrete using samples taken from the field.

The test results can be used to determine specification compliance when results of tests on specimens molded at the time of construction are not available or are defective, and to establish the strength properties of existing construction.
