It is known that conventional high slag cement is difficult to be applied to concrete structures due to its inferior performance such as low early-age strength, high drying shrinkage and high carbonation rate. Those performances of the newly developed high slag cement are improved by using higher blain slag and by increasing SO3 content in connection with a newly developed special water-reducing agent for high flowability and high early-age strength. In this paper it is demonstrated that the properties of the concrete using high slag cement and the water-reducing agent are nearly the same with those using normally used slag cement (JIS Type B slag cement) or ordinarily portland cement 000002066 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000002066 653__ $$ahigh slag cement, ground granulated blast-furnace slag, SO3 content, concrete property 000002066 7112_ $$aFirst International Conference on Concrete Sustainability$$cTokyo (JP)$$d2013-05-27 / 2013-05-29$$gICCS13 000002066 720__ $$aTSUJI, Daijiro$$iKANDA, Tetsushi$$iYONEZAWA, Toshio$$iMITSUI, Kenro$$iINOUE, Kazumasa$$iWACHI, Masahiro 000002066 8560_ $$ffischerc@itam.cas.cz 000002066 8564_ $$s2089065$$uhttp://invenio.itam.cas.cz/record/2066/files/S1-2-3.pdf$$y Original version of the author's contribution as presented on CD, . 000002066 962__ $$r2053 000002066 980__ $$aPAPER
