(1)由于冶金工业废渣的利用率不高,水泥成本不断上涨,酸激发胶凝材料作为一种新型激发手段制得的材料在未来可以得到较好的利用。综合来看,酸激发胶凝材料具有良好的力学性能,在新型建材的应用方面具有很高的研究价值。
(2)酸激发胶凝材料力学性能的影响因素有很多。在研究较多的几种酸性激发剂中,以磷酸和醋酸对胶凝材料力学性能的提升效果最好,且酸的浓度不宜过高。高温度及高湿度有利于胶凝材料强度的提高,掺入一定量外加剂或者富含金属离子的酸性激发剂亦能提高其力学性能。
(3)目前,相比于传统的碱激发胶凝材料,酸激发胶凝材料的研究尚浅,特别是关于激发原理的研究至今尚未形成完整的理论体系,这将是我们未来需要重点探索的方向。
