Silica powder and the amount of slag powder were mixed with 150 kg/m 3, 50 kg/m 3, the concrete demould strength up to 49.1 MPa and the compressive strength after autoclave up to 89.0MPa, to achieve requirements of the national standard GB13476 .
2016-9-9 cement began in 1910, and the Japanese national standard for Portland blast-furnace slag cement (JES 29) was formulated in 1926.some of the study has been done in past which summa-rized as: slag powder and blast furnace slag so the recycling of steel slag can bring enormous benefits and environ-mental benefit to whole society.
The slag powder is further ground into GSP in the laboratory. The chemical compositions of raw materials are given in Table 1. The mass coefficient (K = w(CaO + MgO + Al 2 O 3)/w(SiO 2 + MnO + TiO 2)) of the GSP used was 1.97 according to the Chinese national standard (GB/T
2020-9-6 Steel slag as a cement mixture has been listed in the national standard. After grinding, steel slag powder can be used as an excellent cement mixture, partially replacing clinker to reduce cement production costs, and steel slag cement has a late stage compared with Portland cement.
2016-6-1 The content of residual f-CaO in SS is only 1.23%, which meets the specification of Chinese national standard GB/T20491-2006 “Steel slag powder used for cement and concrete” that requires f-CaO content of steel slag shall be no more than 3% when used in the preparation of cement and concrete . The content of residual f-MgO in SS is only 0.81%.

This standard replaces GB 11674-2005 Hygiene Standard of Whey Powder.
Abstract. This specification covers crushed steel slag coarse and fine aggregates suitable for use in bituminous paving mixtures. The coarse and fine aggregates shall consist of hard, tough, durable pieces of steel slag, and shall be processed, as necessary, by crushing or screening, or both, and magnetic separation for the removal of metallics.
2018-1-30 The applications of steel slag powder and steel slag aggregate in ultra-high performance concrete (UHPC) were investigated by determining the fluidity, nonevaporable water content, and pore structure of paste and the compressive strength of concrete and by observing the morphologies of hardened paste and the concrete fracture surface. The results show that the fluidity of the paste

2020-2-10 The amount of free lime, namely, f-CaO, satisfies the requirement (≤3% m%) of the Chinese National Standard GB/T 20491 “Steel slag powder used for cement and concrete.” The f-CaO is mainly derived from the lime that is put into the steelmaking process for the purpose of slagging.
2019-7-30 National Standard GB/T50081-2002 with a loading rate of 1.2MPa/s. Fluidity testing of the paste was conducted according to Chinese National Standard GB/T8077-2012. Pastes werecast in plastic sealed tubes to preventboth water loss and carbonation, and they were cured under the same conditions used with concretes. At testing ages, hardened
