Comparative analysis of the mechanical properties of concrete block masonry used in constructions within Argentina and Ecuador

Abstract:

A comparative analysis is presented between the mechanical properties of concrete blocks masonry that are used in the construction of houses in Argentina (city of Mendoza) and Ecuador (Chillos Valley). This allowed to evaluate the control applied in the elaboration of such materials. Therefore, the corresponding tests have been conducted to determine the absorption and compressive strength of the specimens. These tests are established in the current regulations of Argentina (IRAM-11561) and Ecuador (INEN 3066). In Ecuador, the study has been performed between 2014 and 2017 by means of a statistical analysis. Samples have been taken from 15 constructions in the Chillos Valley. Later in 2017, in the city of Mendoza the characteristics of the mechanical properties of 15 concrete blocks were determined. The yielded results demonstrated, that 100% of the blocks analyzed in Mendoza meet the requirements, while in Ecuador only 45% are accepted. With respect to the compression resistance, there is a great difference in the quality of the blocks between each studied country. Ecuador obtained only 2.7% acceptance in comparison with Argentina where it reached 72.73%. Regarding the economic cost, the block marketed in Ecuador have been cheaper by approximately 80%.
