Q. How do the aggregate characteristics affect the permeability and shrinkage of concrete? A. The aggregate characteristics are important to permeability in relation to the reduction in w/cm and paste content, which leads to lower permeability. If the water content is reduced or the elastic modulus is increased due to the aggregate characteristics, this should lead to a reduction in drying shrinkage.
