Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or iron compounds, which influences its color.

Raw materials for mortar preparations were de-ionized water, standard sand according to EN-196-1, and Portland cement CEM II 42.5 N/AM SLV produced at the Nesher cement works in Israel. Raw material weighing was performed using a Shimadzu scale with a weighing range of 0-3,000 g and an accuracy of 0.1 g.

The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity. The level

Following the last approach, Fantilli et al. have recently introduced a new cement-based mortar in which carbon dioxide, in the form of dry ice pellets, is added to the mixture like a raw material. By means of this addition, the maximum content of CO 2 that is absorbed by the mortar system is equal to 1.6% of the mass of the CEM I binder.
