| description abstract | This specification covers foaming agents specifically formulated for making preformed foam for use in the production of cellular concrete. The function of this specification is to provide the means for evaluating the performance of a specific foaming agent. The test batch shall conform to the physical requirements prescribed such as density, compressive strength, tensile splitting strength, water absorption and air loss during pumping. The foaming agent being tested shall be used in making test specimens required. | |

| scope | 1.1 This specification covers foaming agents specifically formulated for making preformed foam for use in the production of cellular concrete. 1.2 The function of this specification is to provide the means for evaluating the performance of a specific foaming agent. This is accomplished by using the foaming agent in making a standard cellular concrete test batch (see Test Method C796/C796M) from which test specimens are cast. Then, significant properties of the concrete are determined by tests and compared with the requirements of Section 3. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. | |
