ASTM C495轻质隔热混凝土抗压强度测试方法标准

ASTM C495 Standard Test Method for Compressive Strength of Lightweight Insulating Concrete
ASTM C495 轻质隔热混凝土抗压强度测试方法标准
This test method provides standardized requirements for sampling, molding, curing, and testing lightweight insulating concretes for the purpose of determining compliance with compressive strength and density specifications.

1. Scope
1.1 This test method covers the preparation of specimens and the determination of the compressive strength of lightweight insulating concrete having an oven-dry density not exceeding 50 lb/ft3 (800 kg/m3) as determined by the procedures described herein. This test method covers the preparation and testing of molded 3 by 6-in. (75 by 150-mm) cylinders.
1.2 The values stated in inch-pound units are to be regarded as the standard.
This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
