Description

This course will begin by introducing you to the role of aggregates and how it can be reduced. You will be exposed to how failures occur at the aggregate mortar interface, pores in cement-based materials, and what governs the strength of concrete. You will learn about how recycled aggregates are classified; crushing, grinding of aggregates, and operational energy. This will lead you into pores in cement-based materials, the porosity in the interfacial transition zone, and the porosity in cement. 

Next, you will be introduced to how aggregates are processed and the classification of aggregates. You will gain an understanding of thermal conductivity models in sustainable materials and green building. You will then learn about the factors of enclosed pores against retention fraction, estimation of thermal conductivity, and thermal diffusivity. You will also study the types of brick kilns and carbon balance. This will then lead you to the thermal methods used in sustainable materials. This includes 3D models, steady heat diffusion equation, the conductivity of unit cells, and lambda representation of equivalent conductivity of unit cells. 

Lastly, you will further gain an understanding of the estimation of thermal conductivity. This includes estimated solid conductivity for various kinds of concrete, thermal conductivity against the degree of saturation, Theta degree of saturation, and evaporation condensation. You will learn about the types of brick kilns and carbon balance. You will further gain an understanding of the average specified energy consumption for various kilns, the main source of energy input, environmental performance, and carbon balance.
