3、tions of concrete-making materials.Performance tests onfresh and early-age properties of mortar mixtures can be usefulindicators of concrete performance using similar materials.Theperformance tests described in this guide include mortar-slump,mortar spread,mortar-workability retention,time ofsetting
4、,air entrainment,and hydration kinetics.1.2 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard.Thevalues stated in each system may not be exact equivalents;therefore,each system shall be used independently of the other.Combining values from the tw
5、o systems may result in non-conformance with this guide.Some values only have SI unitsbecause the inch-pound equivalents are not used in guide.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard t
