ABSTRACT

Self-compacting concrete offers significant advantages in infrastructure projects, but its application in specific regions such as Junín has not yet been widely studied. The research evaluates the design of self-compacting concrete with microsilica and plasticizer, focusing on its workability, cost and strength. Using a mix with type I cement, 5-10% silica fume and SikaCem, workability and strength tests are performed. The purpose is to determine the economic feasibility and technical advantages of self-compacting concrete compared to conventional concrete. The results show excellent flowability and passability, with a flow time in the V-funnel of 10.8 seconds and a blocking coefficient of 0.9, complying with regulations. Strength tests reveal values of 407.3, 426.5 and 437.9 kg/cm^² at 7, 15 and 28 days. Although the initial cost is higher ($120/m^³), the cost-benefit analysis highlights a 17% reduction in construction time, with savings in labor and maintenance, and greater durability. The cost/benefit ratio of 1.2061 indicates that self-compacting concrete is economically favorable and efficient for complex construction. The conclusions highlight that, although the initial cost of self-compacting concrete is higher, the long-term savings and advantages in terms of quality and durability justify its adoption. It presents a better understanding of the economic and technical impacts of self-compacting concrete, providing a solid basis for its implementation in infrastructure projects in the region by considering local variables in the analysis, which offers a contextualized perspective relevant to the specific conditions of the area. This study underscores the importance of innovating in construction materials to improve efficiency and sustainability in the industry.
