  • Portland Cement A Brief HistoryThe Screed Scientist®

    A standard cement-sand screed mix is constituted of 1 part of Portland cement and 4.5 parts of aggregates, and water. Cement acts as the binding agent that holds the aggregate together, playing a key role in the setting and hardening properties of the screed. CementCementThe major cements composition and properties Portland cement is made up of four main compounds tricalcium silicate (3CaO · SiO2), dicalcium silicate (2CaO · SiO2), tricalcium aluminate (3CaO · Al2O3), and a tetra-calcium aluminoferrite (4CaO · Al2O3Fe2O3). In an abbreviated notation differing from the normal atomic symbols, these compounds are designated as C3S, C2S

  • CIVL 1101Part 3 Properties of Portland Cement

    When Portland cement is mixed with water, it undergoes a chemical reaction which leads to the hardening of the material. This process is called hydration and the results are the hydration products. The hydration process can be quantified by two characteristics The cement bag should not have hardened or started to hardening. Also Read insufficiency in fineness of grinding and thorough mixing of raw materials. If cement is unsound then avoid using that cement because it leads to damage in concrete. You can ask the cement supplier/manufacturer to replace your material as it does not satisfy the
