    particular material ranging in size. The binder that holds the aggregate together is typically cement. For reasons of simplicity this paper will be mostly talking about pervious concrete made of Portland cement as it is the most common cement used in the world. Portland cement is made of around two-thirds calcium silicates with the remainder being made of iron and aluminum clinker. When mixed with water Portland cement begins to undergo a complex chemical reaction whereby it cures and hardens. The underlying

    Cement is a finely ground powder binder, a material that sets and hardens and can bind other materials together, when mixed with water it forms a hardening paste of calcium silicate hydrates and calcium aluminates hydrates. it evokes highly diverse reactions. Cement is used in mortar (a combination of sand and roughly burnt gypsum) and concrete (bulk rock-like building material made from aggregate, sand, and water). By modifying the raw material mix and the temperatures utilized in manufacturing

    PORTLAND CEMENT Chemical composition. Portland Cement is made up of four main compounds: tricalcium silicate (3CaOSiO2), dicalcium silicate (2CaOSiO2), tricalcium aluminate (3CaOAl2O3), and a tetra-calcium aluminoferrite (4CaO Al2O3Fe2O3). In an abbreviated notation differing from the normal atomic symbols, these compounds are designated as C3S, C2S, C3A, and C4AF, where C stands for calcium oxide (lime), S for silica, A for alumina, and F for iron oxide. Small amounts of uncombined lime and magnesia
