ASTM C495
Full Name
ASTM C495 – Standard Test Method for Compressive Strength of Lightweight Insulating Concrete
Scope
ASTM C495 outlines the procedures for preparing specimens and determining the compressive strength of lightweight insulating concrete with an oven-dry density not exceeding 50 lb/ft³ (800 kg/m³).
Key aspects of this standard include:
- Specimen preparation: it details the process for molding 3 x 6-inch (75 x 150 mm) cylindrical specimens from lightweight insulating concrete.
- Curing conditions: it specifies the curing conditions for the specimens, including initial moist curing followed by air drying.
- Testing procedure: it describes the method for testing the compressive strength of the specimens using a suitable testing machine.
- Calculation: it provides the formula for calculating the compressive strength of the concrete based on the maximum load and cross-sectional area of the specimens.
- Oven-dry density determination: it outlines the procedure for determining the oven-dry density of the concrete, which is an essential parameter for classifying lightweight insulating concrete.
The primary purpose of ASTM C495 is to provide a standardized method for assessing the compressive strength of lightweight insulating concrete, which is crucial for ensuring the quality and performance of this material in construction applications.
