price on chemical composition of cement

Cement - Cement - History of cement The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of more than 2,000 years ago and of subsequent construction work in western Europe.

    All About Hardie Board and Fiber Cement Siding

    Jul 29, 2019 Fiber cement siding can resemble stucco, wood clapboards, or cedar shingles (e.g., HardieShingle 0.25 inches thick), depending on how the panels are textured during the manufacturing process. Pulverized sand, cement, and wood pulp are mixed with water to make a slurry, which is rolled out and pressed together into sheets.

    The Composition of Fiber Cement Board Siding

    May 27, 2012 Portland cement is the most common type of cement used in the world due to the materials versatility. Cellulose fibers compromise as little as 10-15 percent of the composition of fiber cement. Cellulose fiber prevents the siding from buckling and cracking under environmental stress caused by changes in weather.
