Development of an innovative sensor-controlled deicing system built with an optimized electrical cementitious composites ECC

虽然城市地区的除雪涉及相当大的成本，但城市的交通效率可能会因事故和维修而严重延误。在气候条件恶劣的地区，目前用于确保冬季流动性的方法主要包括在道路和人行道上使用除冰盐，以及通过机械扫雪机进行清理。虽然使用道路盐除冰是一种有效的除冰方法，但它会对混凝土造成破坏，并会腐蚀战略基础设施系统中的钢筋，如混凝土桥面。因此，除雪是加拿大基础设施治疗效果恶化的主要原因之一。作为替代解决方案，导电混凝土最近在拉瓦尔大学进行了优化，用于快速加热板材，安装和维修成本较低。该项目专注于开发一种高效的基于传感器的ECC路面控制，以在现代智能城市的背景下清除冰雪。通过利用拉瓦尔大学(9)最近开发的ECC混合料设计，该项目的目标有两个：(1)根据电气系统优化ECC路面的设计；(2)开发一种高效ECC路面的传感器控制系统。该项目基于在真实环境条件下对小ECC板和大ECC板进行的实验活动，以优化和验证它们作为除雪系统的能效。

While snow removal in urban areas involves considerable costs, the transport efficiency of a city can bestrongly delayed by accidents and repairs. The methods currently employed for assuring winter mobility inregions with severe climate conditions consist mainly in the application of de-icing salts to roadways andsidewalks, and the clearing by mechanical snowplow. While the use of road salts for de-icing is an effectivemethod for ice removal, it causes damage to concrete and corrosion of reinforcing steel in strategicinfrastructure systems, such as concrete bridge decks. Thus, snow removal is one of the major causes of therapid deterioration of Canadian infrastructures. As alternative solution, Electrical Conductive Concrete hasbeen recently optimized at Université Laval for rapid heating slabs, with low installation and repair cost.This project focuses on the development of an efficient sensor-based control of an ECC pavement to clearsnow and ice in the context of modern intelligent cities. By taking advantage of the recent ECC mix designdeveloped at Université Laval (9), the objective of this project is twofold: (1) optimize the design of the ECCpavement with respect to the electrical system; (2) develop a sensor-control system for an efficient ECCpavement. The project is based on experimental campaign on small ECC slabs and large ECC slab in realenvironmental conditions for optimizing and verifying their energy efficiency as snow removal systems.
