I-Corps: Smart Materials for Next Generation Wastewater Infrastructure Resilience

I-Corps项目更广泛的影响/商业潜力源于新一代水泥配方，这些配方将使关键废水传输系统的维护、运营和(重新)设计比目前更具成本效益。这个i-Corps项目利用工业副产品的成功再利用，修复已就位的腐蚀公用事业管道，以及创建新一代耐腐蚀废水基础设施。以其他方式作为低价值或危险废物丢弃的工业副产品，以一种同时增强混凝土强度的方式进行回收，同时大幅提高其耐腐蚀性。这个i-Corps项目调查了一种竞争性的商业方法，以减少与更换大量混凝土相关的资源消耗和污染，包括但不限于地下公用事业网络。这使得腐蚀控制战略具有可持续性和协同性，并与关键废水基础设施为环境健康提供的保护相结合。这个i-Corps项目利用普通木炭和钢渣的能力，将抗菌性能赋予胶凝材料。推广新一代廉价的抗菌建材是这个i-Corps项目的核心。通过加入少量的颗粒状工业废物，通过探索新的混凝土外加剂的工程应用，在提高强度的同时有效地防止腐蚀，实现了智力上的价值。虽然大多数混凝土管道修复工作都使用耐酸树脂来保护(损坏的)混凝土管道，但i-Corps项目利用了一种预防性材料方法，可以抑制导致混凝土腐蚀过程的微生物。

The broader impact/commercial potential of this I-Corps project stems from a new generation of cement formulations that will enable more cost effective maintenance, operation and (re)design of critical wastewater transport systems than are currently available. This I-Corps project leverages successful reuse of industrial byproducts for rehabilitating corroding utility conduits in place, as well as creating a new generation of corrosion resistant wastewater infrastructure. Industrial by-products that are otherwise discarded as low value, or hazardous wastes, are recycled in a way that concurrently strengthens concrete while substantially increasing its corrosion resistance. This I-Corps project investigates a competitive commercial approach to reduce resource consumption and pollution associated with replacing large masses of concrete, including, but not limited to subterranean utility networks. This enables a corrosion control strategy that is sustainable and synergistic with the protections that critical wastewater infrastructure provides for environmental health.This I-Corps project exploits the ability of common charcoals and steel slags to confer antimicrobial properties into cementitious materials. Forwarding a new generation of inexpensive antimicrobial building materials is the heart of this I-Corps project. By incorporating small amounts of granulated industrial wastes, intellectual merit is realized by exploring engineering applications for new concrete admixtures that are effective against corrosion while conferring increased strength. While most concrete pipe rehabilitation efforts employ acid resistant resins to protect (damaged) concrete pipe, this I-Corps project leverages a preventative materials approach that inhibits the microbes responsible for the concrete corrosion process.
