Concrete is the most fundamental building material in the modern construction industry. However, although it has high compressive strength, it has relatively low tensile strength. For this reason, concrete is prone to plastic shrinkage cracksat early ages, and in the long term, to drying cracks, freeze-thaw effects, and reduced resistance to fire.
