Abstract:

Longdurability concrete is required for the passengerdedicated railway works, which, compared to the ordinary concrete, imposes more strict requirements on the quality of the cements used. On basis of Chinese standards of "Temporary Stipulations on Design of Durability of Concrete Structures of Railway Works" and "Supplementary Standard on Acceptance of Construction Quality of Concrete Structures of Railway Works", the paper presents the major technical requirements on the cement quality imposed by the longdurability concrete.

Key words: passengerdedicated railway longdurability concrete  , raw material  , cement  , technical requirement
