Portland cement is the most commonly used type of cement and the primary ingredient in producing concrete and mortar. It is a ground, a stony mixture consisting mainly of calcium oxide (quicklime 65%) and silica (silica fume 21%), as well as e.g. alumina (5.6%) or iron oxide (3.4%), with these substances mainly in the following Water dynamics in cement paste at early age prepared ,Cement and Concrete Research Volume 86,August ,Pages 5562 Water dynamics in cement paste at early age prepared with pozzolanic volcanic ash and Ordinary Portland Cement using quasielastic neutron scatteringEffect of Li2CO3 on the properties of Portland cement ,In order to increase the application of CO2 in cementitious materials and to develop new additives for cementbased materials, the effect of lithium carbonate (Li2CO3) on the properties of Portland cement (PC) paste was investigated. The hydration heat of fresh paste was tested and the hydration products were characterized using XRD,
