Design and Control of Concrete Mixtures has been the cement and concrete industry''s primary reference on concrete technology, since PCA published the first U.S. edition in the early 1920s. The current course, based on this industry standard, reflects the latest advances in concrete technology.
Concrete is used for a large variety of constructional purposes. Mixtures of soil and portland cement are used as a base for roads. Portland cement also is used in the manufacture of bricks, tiles, shingles, pipes, beams, railroad ties, and various extruded products. The products are prefabried in factories and supplied ready for installation.
and are, therefore, called hydraulic cement. The name "Portland cement" given originally due to the resemblance of the color and quality of the hardened cement to Portland stone Portland – island in England. Manufacture of Portland cement Raw materials • Calcareous material – such as limestone or chalk, as a source of lime (CaO).
