The global performance of a structure or a system can be improved during the process of its construction or operation or end of life, with multifunction and connected elements. Concrete presents several benefits for being used in this way, in particular with integrated electronic systems. This paper deals with smart concrete through a small size example, a chess game, i.e. board and pawns, to illustrate the potential applications on a larger scale in the field of construction. Different kind of sensors can be used in concrete construction. After comparing the advantages and disadvantages of each, magnetic sensors have been chosen to equip the concrete chessboard, handcrafted in the present work. The concrete used is UHPC (Ultra high performance concrete fiber reinforced or not), a new type of concrete with special properties, for the benefits of its mechanical strength and deformation, self-levelling workability and aesthetic surface rendering. Chess pawns and chess board have been cast with a specific protocol to embed the magnets and the sensor inside the concrete, by taking into account both its flocculation and setting times. Results of the tests show the feasibility to use magnetic sensors in concrete systems and show a good transmission of the magnetic signal through the concrete, which is very promising for further development of new concrete smart systems, that are easy and rentable to implement. The permeability of concrete to magnetic fields, robustness and sensitivity of sensor are the advantages of this application.

智能混凝土:通过智能混凝土国际象棋游戏在建筑 4.0 中的潜在应用说明

结构或系统的整体性能可以在其建造、运行或寿命结束的过程中得到改善,具有多功能和连接元素。以这种方式使用混凝土具有多种好处,尤其是与集成电子系统一起使用时。本文通过一个小尺寸的例子来处理智能混凝土,一个棋局,即棋盘和棋子,以说明在建筑领域更大规模的潜在应用。不同类型的传感器可用于混凝土施工。在比较了各自的优缺点后,选择磁传感器来装备混凝土棋盘,在目前的工作中手工制作。使用的混凝土是UHPC(超高性能混凝土纤维增强或不增强),一种具有特殊性能的新型混凝土,因其机械强度和变形、自流平可加工性和美观的表面渲染等优点。国际象棋棋子和棋盘采用特定协议铸造,通过考虑其絮凝和凝固时间,将磁铁和传感器嵌入混凝土内。测试结果表明,在混凝土系统中使用磁传感器是可行的,并且显示出磁信号通过混凝土的良好传输,这对于进一步开发新的混凝土智能系统非常有希望,这些系统易于实施且可出租。混凝土对磁场的渗透性、传感器的稳健性和灵敏度是该应用的优势。国际象棋棋子和棋盘采用特定协议铸造,通过考虑其絮凝和凝固时间,将磁铁和传感器嵌入混凝土内。测试结果表明,在混凝土系统中使用磁传感器是可行的,并且显示出磁信号通过混凝土的良好传输,这对于进一步开发新的混凝土智能系统非常有希望,这些系统易于实施且可出租。混凝土对磁场的渗透性、传感器的稳健性和灵敏度是该应用的优势。国际象棋棋子和棋盘采用特定协议铸造,通过考虑其絮凝和凝固时间,将磁铁和传感器嵌入混凝土内。测试结果表明,在混凝土系统中使用磁传感器是可行的,并且显示出磁信号通过混凝土的良好传输,这对于进一步开发新的混凝土智能系统非常有希望,这些系统易于实施且可出租。混凝土对磁场的渗透性、传感器的稳健性和灵敏度是该应用的优势。测试结果表明,在混凝土系统中使用磁传感器是可行的,并且显示出磁信号通过混凝土的良好传输,这对于进一步开发新的混凝土智能系统非常有希望,这些系统易于实施且可出租。混凝土对磁场的渗透性、传感器的稳健性和灵敏度是该应用的优势。测试结果表明,在混凝土系统中使用磁传感器是可行的,并且显示出磁信号通过混凝土的良好传输,这对于进一步开发新的混凝土智能系统非常有希望,这些系统易于实施且可出租。混凝土对磁场的渗透性、传感器的稳健性和灵敏度是该应用的优势。
