CONTRABASS: zero-CO2 cemeNt ThRough cArBonation of cAlcium Silicates and aluminateS.We live in a world of concrete. According to the Global Cement and Concrete Association (GCCA) cement is consumed at a rate of ~150 tonnes each second, and it accounts for approximately 8% of all CO2 emissions and 7% of industry energy use. In order to mitigate the negative environmental impacts of concrete, Carbon Capture and Utilization (CCU) is the best available strategy: the GCCA estimates that CCU technologies will represent up to 42% of the CO2 reductions necessary to reach the net zero industrial objective in 2050. The CONTRABASS MSCA-DN will act in this framework, in the pathway towards the zero-CO2 cement and concreteproduction, building a high-quality doctorate network (DN) to investigate the fundamental physico-chemical processes governing the Carbonation of the clinker phases and the cement paste, as well as the subsequent formation of Calcium Carbonate Cements (CCCs).The carbonation ability of clinker and cement is well known, yet for a full implementation of CCCs by 2050, there is an urgent need of fundamental knowledge on the carbonation process. In this scenario, the CONTRABASS DN aims to contribute to the global reduction of CO2 emissions by accelerating the implementation of Calcium Carbonate Cements, developing fundamental knowledge, practical know-how, and a generation of well-trained specialists to overcome the main challenges identified by our industrial and academic partners. CONTRABASS has 5 main objectives:1. To identify the carbonation mechanisms of the clinker components, specially calcium aluminates2. To understand the carbonation processes of the C-S-H gel and the cement paste3. To unravel the factors that govern CaCO3 polymorphism, nucleation and growth rates4. To build databases for thermodynamic and reactive-transport modelling of carbonation5. To communicate effectively the benefits of CCCs to society, media and policy maker.s

CONTRABASS：通过硅酸钙和铝酸盐的碳化实现零二氧化碳水泥。我们生活在混凝土的世界中。根据全球水泥和混凝土协会 (GCCA) 的数据，水泥消耗量约为每秒 150 吨，约占所有二氧化碳排放量的 8% 和工业能源使用量的 7%。为了减轻混凝土对环境的负面影响，碳捕获和利用 (CCU) 是最佳可行策略：GCCA 估计，CCU 技术将占 2050 年实现净零工业目标所需二氧化碳减排量的 42% CONTRABASS MSCA-DN 将在此框架内，在实现零二氧化碳水泥和混凝土生产的道路上，建立一个高质量的博士网络 (DN)，以研究控制水泥和混凝土的基本物理化学过程。熟料相和水泥浆体的碳化，以及随后形成碳酸钙水泥（CCC）。熟料和水泥的碳化能力众所周知，但要在 2050 年全面实施 CCC，迫切需要碳酸化过程的基础知识。在这种情况下，CONTRABASS DN 旨在通过加速碳酸钙水泥的实施、开发基础知识、实用技术和培养一代训练有素的专家来克服由碳酸钙水泥确定的主要挑战，为全球减少二氧化碳排放做出贡献。我们的工业和学术合作伙伴。 CONTRABASS 有 5 个主要目标：1．确定熟料成分（特别是铝酸钙）的碳化机制2。了解C-S-H凝胶和水泥净浆的碳化过程3。揭示控制 CaCO3 多态性、成核和生长速率的因素4。建立碳酸化热力学和反应传输模型数据库5。向社会、媒体和政策制定者有效传达 CCC 的好处。
