PROPERTIES OF ENVIRONMENT CONSIDERATION CONCRETE USING GROUND GRANULATED BLAST-FURNACE SLAG AS THE MINERAL ADMIXTURES AT REPLACEMENT RATIO

Abstract

It is necessary to reduce greenhouse gases in the construction industry to reduce environmental loading. Therefore, we confirmed the performance of concrete using ground granulated blast-furnace slag, which is expected to reduce carbon dioxide emissions. As a result, the influence of the ground granulated blast-furnace slag usage rate on the strength development and durability could be confirmed. In addition, from the results of the accelerated carbonation test, the durability design strength could be set, and a similar value could be set A and B classes as that of normal concrete.
