Concrete plays a fundamental role in civil construction, where its durability and strength are critical factors in ensuring the safety and longevity of structures. In the context of Lima, a coastal city with unique environmental conditions, the choice of cement type takes on special importance due to constant exposure to aggressive agents such as salinity and humidity. This thesis focuses on comparing two categories of cement: traditional Portland cements, widely used in construction, and blended cements, which incorporate additives designed to enhance their properties. The main objective of this research is to evaluate the impact of these two cement categories on the strength and durability of concrete in the coastal context of Lima. Additionally, the study analyzes the results of tests conducted on traditional cements, including Types I and V, and blended cement HS, both in their fresh and hardened states. In the fresh state, the slump test was performed, while in the hardened state, tests for concrete strength and coefficient of permeability were conducted. Furthermore, bibliographic information on compression resistance tests under exposure to sulfates was reviewed. The findings reveal that in the slump test, there is an inverse relationship between the water-to-cement ratio and the slump value, where a higher water-to-cement ratio results in a decreased slump. Regarding the compression resistance test, it is observed that Type I cement exhibits the best strength due to the significant presence of C3a. In the coefficient of permeability test, concrete with HS cement demonstrates greater durability, as it is a blended cement. Finally, based on the literature review, it is concluded that blended concrete is more resistant to sulfate exposure compared to pure cements. In summary, this thesis focuses on the comparative evaluation of pure and blended Portland cements in terms of their ability to withstand adverse environmental conditions in the Lima coastal region. The goal is to provide a solid foundation for making informed decisions in the selection of construction materials in this critical region.
