Cementitious Materials Science

With a focus on portland cement, the book systematically illustrates the composition, properties, and applications of different kinds of cementitious materials, and presents their reaction during the hydration and hardening process. The production technique and applied technology are also discussed with examples. Exercises are added in each chapter, making the work an essential textbook for students.
