Codeofchina.com is in charge of this English translation. In case of any doubt about the English translation, the Chinese original shall be considered authoritative. This standard is developed in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 1596 2005 Fly Ash Used for Cement and Concrete. The following technical changes have been made with respect to GB/T 1596-2005 (the previous edition): ——"Reference sample: in conformity with GSB 14-1510 Standard Cement Sample for Strength Inspection" is replaced by "reference cement: in conformity with GSB 14-1510, or portland cement or ordinary portland cement with strength grade of 42.5 which is in conformity with GB 175 and meets the relevant requirements of this standard" (see 3.2, also 3.2 in Edition 2005); ——In the technical requirements, "total mass fraction and indicators of density and strength activity indexes of SiO2, Al2O3, and Fe2O3" are added in the "fly ash for mixing concrete and mortar"; as for the fineness indicator of Grade II fly ash, "residue on 45μm square hole sieve shall be no greater than 25 % " is replaced by "residue on 45μm square hole sieve shall be no greater than 30%"; the ignition loss of Grade III fly ash is changed from "no greater than 15.0%" to "no greater than 10.0%"(see 6.1, also 6.1 in Edition 2005); ——In the technical requirements, the indicators of "total mass fraction and density of SiO2, Al2O3, and Fe2O3" are added in the "fly ash as active admixture for cement" (see 6.2); ——The radioactive index "accepted" is replaced by "in conformity with the requirements of GB 6566 for materials of major building structure" (see 6.2, also 6.3 in Edition 2005); ——The content of calcium sulfate hemihydrate is required to be detected for fly ash produced with dry or semi-dry desulfurization process, for which the specified indicators and test methods are added (see 6.4 and 7.5); ——The mix ratio of radioactive testing samples is added (see 7.9); ——The mortar fluidity of reference cement in water demand ratio test for fly ash is changed from “130 mm~140 mm” to “145 mm~155 mm”, and the test procedure is modified (see Annexes A.3 and A.5, and also Annexes B.3 and B.5 in Edition 2005). This standard was proposed by China Building Materials Federation. This standard is under the jurisdiction of SAC/TC 184 National Technical Committee on Cements of Standardization Administration of China. The previous editions of the standard replaced by this standard are as follows: ——GB/T 1596-1979, GB/T 1596-1991 and GB/T 1596-2005. Fly Ash Used for Cement and Concrete 1 Scope This standard specifies the terms and definitions, classification, grading, technical requirements, test methods, inspection rules, packaging, marking, transport and storage of fly ash used for cement and concrete. This standard is applicable to fly ash serving as admixture for mixing of mortar and concrete as well as that serving as active admixture in cement production. 2 Normative References The following documents are indispensable for the application of this standard.
