Portland Cement Concrete - an overview

Portland cement concrete is a brittle material. The main reason for incorporating fibres into a cement matrix is to improve the cracking deformation characteristics, increasing not only the toughness, impact and tensile strength, but also eliminating temperature and shrinkage cracks.

The Differences Between Cement, Concrete, and Mortar

2021-6-30  You might see cement referred to as Portland cement. This is because it was first made in the 1800s in England by a mason, Joseph Aspdin of Leeds, who likened the color to the stone from the quarries on the island of Portland, off the coast of England. Today, Portland cement remains the most common type of cement used in building materials.

Furthermore, the slopes of the two trend lines are almost comparable. Based on these findings, it seems that the formation of Al-tobermorite does not have a direct impact on the compressive strength.
