摘要
以高炉矿渣为主要原料,用石灰作激活剂,硬石膏、氯化钙作早强剂,通过试验制备一种高炉矿渣基胶凝材料。以铁尾矿、粉煤灰和河砂为骨料,用所制备的胶凝材料和普硅水泥作胶结料进行不同浓度砂浆的应用性能试验。试验表明:相同条件下,试验制备的高炉矿渣基胶凝材料能完全代替水泥用于矿山生产,并具有生产成本低,节能降耗的优点。
In this paper, one new cementation material has been prepared using the blast-furnace slag （BFS） as the main material, lime as activator, anhydrite and calcium chloride as early strength agent, and iron tailings , fly ash and sand as aggregate. The application performance of new material and ordinary Portland cement has been compared using them as binder in mortars with different concentration. The result showed that under the same conditions, the prepared blast-furnace slag cementation material can completely replace cement in mine backfilling, and has the advantages of low cost, saving energy and reducing consumption.
