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

违禁品：通过碳酸钙和铝制的碳酸化零-CO2水泥。我们生活在混凝土世界中。根据全球水泥和混凝土协会（GCCA）水泥的统计，每秒约150吨，它约占所有CO2排放量的8％，占行业能源使用的7％。为了减轻混凝土的负面环境影响，碳捕获和利用（CCU）是最好的策略：GCCA估计，CCU技术将代表2050年达到零净工业目标所需的二氧化碳所需的42％，该co2降低到2050年。高质量的博士学位网络（DN），以调查管理熟料阶段和水泥糊的碳化的基本物理化学过程，以及随后的碳酸钙水泥（CCC）的形成。熟料和水泥的碳化能力是众所周知的，尚不知道CCC的迫切实施，这是一个全面的CCC，是CCC的全面实施。在这种情况下，违禁DN旨在通过加速碳酸钙水泥的实施，发展基本知识，实践知识和一代良好训练的专家来克服我们的工业和学术党所确定的主要挑战，从而为全球减少CO2排放做出贡献。违禁品有5个主要目标：1。确定熟料成分的碳酸化机制，特别是铝钙2。了解C-S-H凝胶和水泥粘贴的碳酸过程。阐明控制CaCO3多态性，成核和生长速率的因素4。构建用于碳化的热力学和反应性传输建模的数据库5。有效地传达CCC对社会，媒体和政策制定者的好处
