Standard Specification for Foaming Agents Used in Making Preformed Foam for Cellular Concrete

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 C 796) from which test specimens are cast. Then, significant properties of the concrete are determined by tests and compared with the requirements of Section .
1.3 The values stated in inch-pound units are to be regarded as the standard.
