Introduction

• Portland cement was developed in the nineteenth
  century.
• It has become one of the most important building
  materials.
• It has complex chemical compositions, but the
  main cementing compound is calcium silicate
  hydrate.
• Ordinary Portland cement can be modified for high
  early strength, for sulfate resistance, for low
  heat production, or for use in masonry.

4
Introduction

• For architectural use, it can be formed white,
  black, or in various colors.
• High-alumina cement and magnesium-oxy-chloride
  cement are different from Portland cement in
  chemical compositions.
