Waste marble powder (WMP) is industrial waste characterized by serious environmental pollution and a low recycling rate. To determine if WMP can be used for partial cement replacement in concrete production, more in-depth and comprehensive research is needed. Moreover, cellular concrete has deficient strength, durability and environmental friendliness, which could be improved by incorporating both silica fume (SF) and WMP. Hence, this study investigated the effects of SF (0%, 2.5%, 5% and 10%) and WMP (0%, 5%, 10%, 15% and 20%) on the mechanical and durability properties of cellular concrete. The slump, density, water absorption and mechanical properties of cellular concrete were discussed. The resistance of cellular concrete containing SF and WMP to MgSO₄ and H₂SO₄ attack was evaluated by changes in compressive strength, splitting tensile strength, mass and microstructure. The cellular concrete with 10% SF and 5–20% WMP exhibited the optimal mechanical and durability properties. After H₂SO₄ attack, this concrete exhibited significantly higher mechanical properties than the control group and substantially less concrete deterioration and mass (0.20–1.49%), compressive strength (27.40–40.20%) and splitting tensile strength (37.26–46.04%) losses. Moreover, scanning electron microscopy (SEM) images showed that specimens containing SF and WMP (especially SF10 and SF10M5) exhibited better resistance to MgSO₄ and H₂SO₄ attack. Overall, appropriate SF and WMP replacements of cement significantly improved the mechanical and durability properties of cellular concrete, especially after sulfate acid attack.

大理石废粉（WMP）是工业废料，其特征是严重的环境污染和低回收率。为了确定WMP是否可用于混凝土生产中的部分水泥替代，需要进行更深入，更全面的研究。此外，多孔混凝土的强度，耐久性和环境友好性不足，可以通过掺入硅粉（SF）和WMP来改善。因此，本研究调查了SF（0％，2.5％，5％和10％）和WMP（0％，5％，10％，15％和20％）对多孔混凝土的机械和耐久性能的影响。讨论了蜂窝混凝土的坍落度，密度，吸水率和力学性能。含SF和WMP的多孔混凝土对MgSO ₄和H ₂ SO ₄的抗性通过抗压强度，劈裂抗张强度，质量和微观结构的变化来评估冲击强度。具有10％SF和​​5-20％WMP的多孔混凝土表现出最佳的机械和耐久性能。在H ₂ SO ₄侵蚀后，该混凝土的机械性能显着高于对照组，混凝土的变质和质量（0.20–1.49％），抗压强度（27.40–40.20％）和抗拉强度（37.26–46.04％）显着降低。损失。此外，扫描电子显微镜（SEM）图像显示，包含SF和WMP（尤其是SF10和SF10M5）的样品表现出对MgSO ₄和H ₂ SO _4的更好耐受性攻击。总体而言，适当地置换SF和WMP水泥可以显着改善多孔混凝土的机械性能和耐久性，特别是在硫酸侵蚀后。
