  • BASIC CONCRETE INFORMATION

    Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or concrete mix, will be poured and harden into .

  • Concrete: Scientific Principles

    The other major components of portland cement, tricalcium aluminate and tetracalcium aluminoferrite also react with water. Their hydration chemistry is more complicated as they involve reactions with the gypsum as well. Because these reactions do not contribute significantly to strength, they will be neglected in this discussion.

    Sounds straightforward, right? In fact, there are five major types of Portland cement, as defined by the American Society for Testing and Materials (ASTM): Type I: general purpose, suitable for most buildings, bridges, pavements, etc. Type II: moderate sulfate resistance, suitable for concrete exposed to either soil or water that contains sulfate ions

  • Chemical Compounds in Cement

    Major Chemical Compounds in Cement Main chemical compounds of Portland cement with their chemical formula & their percentages by weight are as follows. Of the all, the silicates C 3 S and C 2 S are the most important compounds, which are responsible for the strength of hydrated cement paste.
