This EAGER award is intended to test the hypothesis that waste materials containing significant amounts of alkali or alkaline earth metal oxides have sufficient carbonation potential to permanently store at least a part of the CO2 generated from industrial process. Industrial alkaline waste materials, viz., cement kiln dust (CKD), high carbon fly ash from fluidized bed coal combustion, fine glass powder from highway glass bead manufacturing, and lime mud from paper manufacturing will be investigated. It is also proposed to investigate the beneficial utilization of the resulting carbonated end products in concrete applications. The specific research objectives for this EAGER study are: (i) To quantify the efficiency of industrial alkaline waste materials in their as-procured condition for CO2 sequestration; and (ii) To evaluate the behavior of the carbonated end products in cement pastes so as to lay the foundation for their potential application in concretes.The waste materials to be evaluated in this study are generated in industrial settings that emit significant quantities of CO2. If successful, this project will provide a pathway for the utilization of the CO2 emitted from a particular industrial process towards the beneficiation of the waste material from this process. Two, the beneficiated (carbonated) waste products will be evaluated in this study for their potential application as binding materials in concrete. If the carbonated products can be utilized in concrete applications, this will contribute towards making the concrete ?greener?.

这个急切的奖项旨在检验这样一个假设，即含有大量碱或碱土金属氧化物的废物具有足够的碳化潜力，可以永久存储至少一部分工业过程产生的二氧化碳。调查对象包括水泥窑灰、高碳飞灰、公路玻璃微珠生产中产生的细玻璃粉、造纸产生的石灰泥等工业碱性废弃物。还建议调查由此产生的碳化最终产品在混凝土应用中的有益利用。这项急切研究的具体研究目标是：(I)量化工业碱性废物在其获得的条件下对二氧化碳的固定效率；以及(Ii)评估碳化最终产物在水泥浆体中的行为，为其在混凝土中的潜在应用奠定基础。本研究评估的废物产生于排放大量二氧化碳的工业环境中。如果成功，该项目将提供一条途径，利用特定工业过程排放的二氧化碳，使该过程产生的废物得到提炼。第二，本研究将对浓缩(碳化)废品作为混凝土粘结材料的潜在应用进行评估。如果碳化产品能够用于混凝土应用，这将有助于使混凝土变得更环保。
