Determination of calcium oxide and magnesium oxide from silica filtrate its principle
Answers
Answer:
Calcium and Magnesium oxides content in selected cement were determined. The selected cement samples revealed the following: Ashaka Cement – CaO (66.75) and 3.97% (MgO); Sokoto Cement – CaO (63.7%) and MgO; (3.789%)Dangote Cement – CaO (61.9%), MgO (3.69%) and Gboko Cement – CaO (57.45) and MgO (3.62%). Ashaka Cement demonstrated the highest percentage of calcium oxide (CaO) and Magnessium oxide (MgO). The percentage of calcium oxide (CaO) falls within the standard reference value for CaO in cement (i.e. 62.68%) except for Gboko Cement which falls below the reference value. While the MgO content were found to be higher than the standard reference value. The research proffered some recommendations to chemists and construction workers for the betterment of our country now and the future.
