Durability, evaluation of CO2-injected ready mixed cement

CarbonCure Technologies已经证明，在新鲜或早期水合状态下暴露于CO2生产的混凝土产品（类似于砌块）受益于提高的强度，降低的吸水性，提高的抗氯离子渗透性和提高的冻融性能。最重要的是，二氧化碳吸收到混凝土中永久地隔离二氧化碳，并允许开发具有改进性能的可持续“绿色”建筑产品。 在该项目中，CarbonCure Technologies（CCT）将研究将该技术扩展到预拌混凝土。CCT将在多伦多的特定混凝土工厂地点安排其工艺的工业试验。CCT人员还将与多伦多大学的研究人员合作，为各种耐久性测试铸造特定的测试样本。混凝土样本将被运送到多伦多大学，在那里将使用标准和新的非标准耐久性测试方法对其进行评估和分析。此外，该过程将在实验室中模拟，以铸造小规模的标本，用于一些微观分析。这项研究的结果将有助于CarbonCure Technologies更好地了解其CO2工艺所提供的改进机制，并使他们能够证明其潜力的好处。 工业客户。

CarbonCure Technologies has shown that concrete products (analogous to masonry blocks) produced with exposure to CO2 in the fresh or early hydration state benefit from improved strength, reduced water absorption, improved resistance to chloride permeability, and improved freeze-thaw performance. Most importantly, carbon dioxide absorption into the concrete permanently sequesters CO2 and allows the development of sustainable "green" building products with improved performance. In this project, CarbonCure Technologies (CCT) will investigate extending this technology to ready mixed concrete. CCT will arrange for industrial trials of their process at specific concrete plant locations in Toronto. CCT personnel will also work with University of Toronto researchers to cast specific test specimens for the various durability tests. The concrete specimens will be transported to the University of Toronto where they will be evaluated and analyzed using both standard and new, non-standard durability test methods. In addition, the process will be simulated in the laboratory to cast small scale specimens for use in some of the microscopic analysis. The results of this research will help CarbonCure Technologies better understand the mechanisms of improvements afforded by their CO2 process and allow them to demonstrate the benefits to their potential industrial clients.
