    2. Overall Synopsis and Objective of the Project
    Cement and concrete are the most widely used construction materials in the world due to factors such as their strength, durability, and economic benefits. The cement industry is one of the primary producers of CO2, creating up to 5-8% of worldwide man-made emissions. On the other hand, carbonation is a natural phenomenon affecting commonly used cement and concrete materials. The carbonation reaction between carbon dioxide and the calcium compounds in the cement results in the permanent fixation of carbon dioxide as a thermodynamically stable calcium carbonate. This project aims to develop methods to establish high-performance cement and concrete using accelerated carbonation technology and to enhance the CO2 uptake capacity in cement and concrete materials. This project is an interdisciplinary laboratory/engineering investigation focused on the following areas:

    ● Design and test of accelerated carbonation curing for precast concrete
    ● Material design to enhance CO2 uptake capacity in cement and concrete materials
    ● Evaluation of the performance of the carbonated cement and concrete materials

    The work scope of this project is as follows:

    ● Design and test of accelerated carbonation curing for precast concrete: The accelerated carbonation curing chamber to control parameters such as the concentration of CO2, the pressure, and the temperature will be designed and manufactured to assist with the effective uptake of CO2 into cement and concrete materials.
    ● Material design to enhance the CO2 uptake capacity in cement and concrete materials: Material design to enhance the CO2 uptake capacity in cement and concrete materials will be conducted using a monocarbonate formation in Portland cement concrete and using a geopolymer (alkali-activated cementitious materials) concrete. The modeling and a feasibility study will be performed to develop methods for the highperformance establishment of cement and concrete using accelerated carbonation technology.
    ● Evaluation of the performance of the carbonated cement and concrete materials: Reaction mechanisms, results of carbonation and the chemical and physical changes of the hydration products, strength and durability levels will be experimentally tested. In addition, the CO2 uptake level will be analyzed and compared with the existing technologies.
