The 1 st International Symposium on Nanotechnology in Construction will deal with bothnanomaterials and nanosensors for concrete construction, which will be beneficial to thecurrent research. Developments in nanotechnology have already enabled bettercharacterization of fiber-reinforced cementitious composites with the use of fiber push-out tests to determine fiber-matrix bond strength, an important factor in the overallperformance of such composites. The use of nanosensors in concrete panels and otherconcrete construction, would increase the understanding of hydration and damageevolution. In a research setting, nanosensors could be used to detect crack initiation inspecimens under loading or to monitor the setting of concrete by detecting thedevelopment of hydration products. The incorporation of nanosensors in concrete panelswould allow for real-time monitoring of the structure, providing information on durabilityand early damage detection. The application of nanotechnology to concrete constructionis still extremely new. Attendance at the 1 st International Symposium onNanotechnology in Construction will allow the researchers to participate in an importantexchange of ideas and learn how best to apply these new ideas in developing theirconcrete panels.

第一届国际建筑纳米技术研讨会将同时讨论纳米材料和纳米传感器在混凝土建筑中的应用，这将有助于当前的研究。纳米技术的发展已经使纤维增强水泥基复合材料的更好的表征与使用的纤维推出测试，以确定纤维基体的粘结强度，在这样的复合材料的overallperformance的一个重要因素。在混凝土面板和其他混凝土结构中使用纳米传感器，将增加对水化和损伤演化的理解。在研究环境中，纳米传感器可用于检测负载下的裂纹萌生检查或通过检测水化产物的发展来监测混凝土的凝固。在混凝土面板中加入纳米传感器将允许对结构进行实时监测，提供有关耐久性和早期损伤检测的信息。纳米技术在混凝土建筑中的应用仍然是非常新的。参加第一届国际研讨会纳米技术在建筑将使研究人员参与一个重要的思想交流，并学习如何最好地应用这些新的想法在发展他们的混凝土面板。
