LIMESTONE CALCINED CLAY CEMENT.

This paper aims at assessing the return on investment and carbon mitigation potentials of five investment alternatives for the limestone calcined clay cement in a long-term horizon appraisal (15 years). Anticipated growing demand for cement. This research has explored the ,beneficial contribution of a new available technology, LC³ cement, resulting from the combination of clinker, calcined clay and limestone, with a capacity of replacing up to 30% or 40% of clinker in cement. Increasing the production of conventional blended cements instead brings only marginal economic benefits without supporting the needed increase in production capacity. The conducted study also shows that, in spite of the extra capital cost required for the calcination of kaolinite clay, LC³ drops production costs in the range of 15–25% compared to conventional solutions. A coarse sharp sand from sea was gotten with gypsum, calcined clay, limestone, granite and opc was taken to the laboratory for proper research in which 40% and 30% of calcined clay
was being use for the research with gypsum, coarse aggregate, limestone, fine aggregate and
opc using it likewise with coarse aggregate and fine aggregate as control. In this research we are able to obtain the comprehensive strength for 3days,7days, 14days and
28 days. The sieve analysis was gotten, bleeding, workability, setting time, porosity, segregation and water absorption
