This research investigates the application of Life Cycle Cost (LCC) analysis in the construction industry, focusing on reinforced concrete structures. LCC analysis goes beyond initial building costs, encompassing all expenses throughout a structure's service life. Among various service life prediction models, Life-365 and DURACON are noteworthy. Life-365, a specialized computer program, predicts the life cycle cost of reinforced concrete exposed to chlorides. This paper presents a case study using Life-365 to compare the LCC of two concrete mixes, TM1 and TM2, in Mumbai, a location with conditions conducive to chloride exposure. The study uses average monthly temperatures and location-specific input parameters to evaluate the LCC of M70-grade concrete mixes with different compositions, including Fly Ash, GGBS, and Micro Silica as partial cement replacements. Results indicate that quaternary blended M70 grade concrete, incorporating supplementary cementitious materials (SCMs), not only enhance durability but also offers economic benefits, reducing overall life cycle costs. These findings provide valuable insights for engineers and decision-makers, promoting durable, cost-effective, and sustainable concrete structures.
