1. Interaction of water with supplementary cementitious materials: Hydration mechanism, microstructure and moisture transport
Abstract : Supplementary cementitious materials (SCMs) offer a sustainable solution to reduce carbon emissions from the production of cement and concrete. This dissertation explores the impact of SCMs and the related additives on the hydration process of cementitious materials, which can affect their microstructure and transport properties. READ MORE

2. Mechanical activation of clay : a novel route to sustainable cementitious binders
Abstract : EU Sustainable Development Strategy planned to achieve improvement of life-quality by promoting sustainable production and consumption of raw materials. On November 2018, EU Commission presented a long-term strategy, aiming among others a climate-neutral economy by 2050. Cement production is contributing to 6-10% of the anthropogenic CO2 emissions.

3. Revalorization of poorly reactive sources by mechanochemical activation : An alternative approach for sustainable cementitious binders
Abstract : The latest report from the Intergovernmental Panel on Climate Change made once again clear the urge to take immediate actions to reduce the emissions of carbon dioxide and other greenhouse gases. Among the UN Sustainable Development Goals (SDGs), Nr. READ MORE

4. Water and alkali salts in the hydrating and hardened green cement-based materials: Hydration process, moisture content and transport
Abstract : Reducing CO2 emissions in the production of cementitious binder is the most effective way to decrease the environmental impact of the construction industry, so a large amount of supplementary cementitious materials (SCMs) has been used in the green concrete. Both the SCMs and alkali salts in binders influence the hydration process and the structure in hardened cement-based materials. READ MORE

5. Self-Healing Concrete
Abstract : Concrete is a brittle material prone to cracking due to its low tensile strength. Crack repairs are not only expensive and time-consuming but also increase the carbon footprint. Designing a novel concrete material possessing the ability to self-repair cracks would enhance its sustainability. READ MORE
