Abstract

Portland cement production dominates a major part of CO2 emission generated from construction materials and its reduction in terms of concrete is of particular significance. As a technical solution, the authors have been developing an HS concrete with a granulated blast furnace slag content as high as 65 percent for underground mass concrete constructions. In this paper, aiming at wider dissemination of massive HS concrete, the standard correction values of concrete compressive strength in structure (28SM91 value) were verified. The correction values of concrete strength in structure 28SM91 is 3N/mm2 through all season examined by statistics study.
