Present study discusses the role of nano-composite materials to achieve mechanical, durable and corrosion resistance properties of high-strength concrete mixtures. Silicon and calcium-based nano-composite materials such as nano-SiO₂, nano-CaCO₃ and nano-Ca(OH)₂ are replaced in cement in various binary and ternary combinations by varying the dosage 2% and 5% by weight. In addition to the strength performance, specific tests such as water absorption, water sorptivity, permeability, density, coefficient of water absorption, acid penetration, weight loss and the LQR resistance have been further performed to investigate the impact on durability and corrosion resistance. Experimental results showed that the mechanical properties of concrete mixtures have been enhanced (10–45%) due to the presence of nano-materials at their optimum dosage. The optimum dosage of nano-composite materials with cement in the ternary combination was found to be 2% for enhanced mechanical performance and 5% for increased corrosion resistance. However, higher durability results (5% to 60%) were achieved in binary combination with 2% replacement. The improved performance of durability and corrosion resistance was achieved due to the increased surface area of nano-composite materials, which stimulates both pozzolanic reactivity and effective filling of voids in the concrete. The scanning electron microscopy (SEM) and X-ray diffraction (XRD) results have also used to identify the particle distribution in the concrete specimen. The entire investigation shows that the optimum dosage of nano-composite materials gives better performance in concrete specimen.

本研究讨论了纳米复合材料在实现高强度混凝土混合物的机械，耐久和耐腐蚀性能方面的作用。硅和钙基纳米复合材料，例如nano-SiO ₂，nano-CaCO ₃和nano-Ca（OH）₂通过改变2％和5％重量的用量，可以以各种二元和三元组合取代水泥中的二氧化硫。除强度性能外，还进行了诸如吸水率，吸水率，渗透性，密度，吸水率，酸渗透率，重量损失和耐LQR性的特定测试，以研究其对耐久性和耐腐蚀性的影响。实验结果表明，由于纳米材料以最佳剂量存在，混凝土混合物的机械性能得到了提高（10–45％）。发现三元结合物中的纳米复合材料与水泥的最佳用量为2％，以提高机械性能，而5％则是提高耐腐蚀性。然而，二元组合（替代2％）可获得更高的耐久性结果（5％至60％）。由于纳米复合材料表面积的增加，从而提高了耐久性和耐腐蚀性，这既促进了火山灰反应性，又有效地填充了混凝土中的空隙。扫描电子显微镜（SEM）和X射线衍射（XRD）结果也已用于鉴定混凝土试样中的颗粒分布。整个研究表明，纳米复合材料的最佳用量在混凝土试样中具有更好的性能。扫描电子显微镜（SEM）和X射线衍射（XRD）结果也已用于鉴定混凝土试样中的颗粒分布。整个研究表明，纳米复合材料的最佳用量在混凝土试样中具有更好的性能。扫描电子显微镜（SEM）和X射线衍射（XRD）结果也已用于鉴定混凝土试样中的颗粒分布。整个研究表明，纳米复合材料的最佳用量在混凝土试样中具有更好的性能。
