水泥行业需要立即采取行动实现碳中和。将生物炭集成到水泥中作为钢筋混凝土的组成部分，通过促进碳封存，在建筑行业减少碳排放方面具有潜力。为了追求环保实践和改善水泥复合材料的物理性能，本研究调查了木质基、微米级生物炭作为非碳酸盐原料的性质，包括其化学成分、形貌和润湿性。木质纤维素微生物炭的表征及其对水泥复合材料力学性能的影响是本研究关注的重点。水泥被部分替代为不同重量百分比的微米级生物炭（1、3和5 wt%），并通过7天和28天后的抗压强度测试进行评估。结果表明，微米级生物炭在替代水泥时仍能保持强度。值得注意的是，28天后，纯水泥样品的抗压强度为29.6 MPa，而3 wt%生物炭替代样品的抗压强度为30.9 MPa，表明强度提高了4.4%。这项研究通过为该行业提供减少碳排放的绿色解决方案，为可持续建筑实践做出了贡献。
