基于木质素的混合外加剂及其在水泥复合材料 制造中的作用
摘要
氧化铝,设计了一种获得功能性无机-有机杂化材料的技术。Al2O3-木质素和Al2O3-木质素磺酸盐体系采用研钵
研磨机和行星式球磨机的机械方法制备,可以有效地获得足够均匀的产品。这通过使用傅里叶变换红外光谱和热重
分析得到证实。在下一步中,开发的混合材料被用作水泥混合物中的功能性外加剂,从而有助于形成现代、可持续
的建筑材料。本文研究了原始组分和混合材料如何影响所得砂浆的机械性能。生物聚合物,尤其是木质素的混合物,
导致水泥复合材料具有更大的可塑性,而氧化铝则提高了它们的强度性能。经证实,含有0.5 wt.%氧化铝-木质素材
料的体系最适合用作水泥砂浆外加剂。
