SLUG, PRODUCTION METHOD OF SLUG, AND CIVIL ENGINEERING MATERIAL
To provide a slug having excellent boron elution resistance, a production method of the slug, and a civil engineering material using the slug.SOLUTION: Slug containing a glass phase, and, as a crystal phase, at least CaMg(SiO)and B: 0.15 mass% or larger, Ba: 1.0 mass% or larger and smaller than 2.5 mass%, and/or Sr: 0.40 mass% or larger and smaller than 1.7 mass%, in which the following Index G obtained by XRD measurement with a Cu-Kα line as a radiation source is 7.0 or larger, in the glass phase, a content of Ba is smaller than 8.0 mass%, and a content of Sr is smaller than 7.0 mass%, and has excellent boron elution resistance. Index G=I[glass]/(I[27°]+I[32°]+I[47°])×100.SELECTED DRAWING: None
【課題】耐ホウ素溶出性に優れるスラグ、上記スラグの製造方法、及び、上記スラグを用いた土木用資材を提供する。【解決手段】ガラス相と、結晶相として、少なくともＣａ３Ｍｇ（ＳｉＯ４）２と、Ｂ：０．１５質量％以上と、Ｂａ：１．０質量％以上２．５質量％未満、及び／又は、Ｓｒ：０．４０質量％以上１．７質量％未満と、を含有するスラグであって、Ｃｕ−Ｋα線を線源としたＸＲＤ測定によって得られる下記Ｉｎｄｅｘ Ｇが７．０以上であり、ガラス相中、Ｂａの含有量が８．０質量％未満、且つ、Ｓｒの含有量が７．０質量％未満である、耐ホウ素溶出性に優れるスラグ。Ｉｎｄｅｘ Ｇ＝Ｉ［ｇｌａｓｓ］／（Ｉ［２７°］＋Ｉ［３２°］＋Ｉ［４７°］）×１００【選択図】なし
