In the present case study the improvement in one day strength in Portland PozzolanavCement (PPC) was done with different methods. PPC were collected from an operating cement plant of UltraTech Cement Ltd. with annual cement capacity of 2.75 million tonnes approximately in eastern India. Cement samples were collected from the plant and also from the other major competitor cement players available in market. The physical properties such as Blaine Surface Area, Setting Time, Normal Consistency and Compressive Strength of 1, 3, 7 & 28 days of all collected cement samples were determined. It was observed that one day strength was having scope for further improvement. Keeping in view the one day strength and its impact on customer satisfaction, the project was taken up and the team was formed to start the project. Brainstorming on the issue was done and number of ideas generated. Each idea was critically studied thoroughly with positive and negative impact on process. Use of mineral gypsum in place of chemical gypsum was found suitable from quality, cost and process point of view.
