Slag, slag manufacturing method, and civil engineering materials

摘要

PROBLEM TO BE SOLVED: To provide a slag having excellent boron elution resistance, a method for producing the slag, and a civil engineering material using the slag. SOLUTION: With the glass phase As the crystal phase, at least Ca ₃ Mg (SiO ₄ ) ₂ and B: 0.15% by mass or more, A slag containing Ba: 1.0% by mass or more and less than 2.5% by mass, and / or Sr: 0.40% by mass or more and less than 1.7% by mass. The following Index G obtained by XRD measurement using Cu-Kα ray as a radiation source is 7.0 or more. A slag having an excellent boron elution resistance, having a Ba content of less than 8.0% by mass and an Sr content of less than 7.0% by mass in the glass phase. Index G = I [glass] / (I [27 °] + I [32 °] + I [47 °]) x 100 [Selection diagram] None
