<p>PROBLEM TO BE SOLVED: To provide a concrete composition in which alkali-silica reaction is inhibited. SOLUTION: The preparation process of this concrete composition comprises: using ecocement (ecological cement), or preferably ecocement having a <=0.6 wt.% alkali content, as a component of the composition; and using, as a part or all of aggregate in the composition, a slag composition produced as a byproduct in a metal refining process.</p> |
