Studies Carried Out on Concretes produced with LC3 According to Cuban Standard NC 120: 2014

摘要

In order to implement the low carbon cement (LC3) as part of the Cuban regulations, a study of durability in concretes manufactured with this cement was developed, in different conditions of aggressiveness according to the performance parameters established in the NC 120: 2014 "Hydraulic Hydraulic-Specifications", the taking of witnesses of the HI, H2, and H4 concretes elaborated in 2016 was carried out. Carbonation depth tests, air permeability, chloride ion migration, were carried out. electrical resistivity, effective to determine the changes experienced by the series 1.5 years versus the series 6 months and the concretes made with cement under carbon LC3 compared to those made with Ordinary Portland Cement (CPO). Subsequent to the analysis of the results, it can be verified that the concretes made with LC3 showed to be in a range of 11-16 times superior in their behavior to the electrical resistivity that those made with Portland cement and 15-22 times more resistant to the chloride ion penetration that those made with CPO, also show a more favorable performance with the passage of time.
