The durability of building materials, such as stone and concrete, depends on their porosity and permeability; that is, if they are highly porous and permeable, gas and water can penetrate through them, which can lead to different types of deterioration of the material. Through a series of computer animations, it is intended to demonstrate the concept of packing density of materials and its influence on the penetrability characteristics and, the resulting, durability performance, such as corrosion, freeze-thaw scaling and salt-induced disintegration. These computer displays will be accompanied by physical exhibits, to illustrate the usefulness of in situ testing and monitoring the behaviour using embedded sensors. The working principle of sensors will be illustrated using these exhibits, which are intended to stimulate an interest on the physics of material behaviour in undergraduate students in Science and Engineering and an awareness amongst engineers and professionals in the construction industry on how to ensure sustainable and durable construction materials.

石材和混凝土等建筑材料的耐久性取决于它们的孔隙率和渗透性;也就是说，如果它们是高度多孔和可渗透的，气体和水可以渗透其中，这可能导致材料的不同类型的劣化。通过一系列计算机动画，旨在展示材料填充密度的概念及其对渗透性特征的影响，以及由此产生的耐久性性能，例如腐蚀、冻融结垢和盐致崩解。这些计算机展示将伴随着实物展品，以说明使用嵌入式传感器进行现场测试和监测行为的有用性。传感器的工作原理将使用这些展品进行说明，旨在激发科学与工程专业本科生对材料行为物理学的兴趣，以及建筑行业工程师和专业人员对如何确保可持续和耐用建筑材料的认识。
