Comparative analysis of stone aggregates for the manufacture of concrete in the construction of civil works

Abstract:

This research is a comparative analysis between aggregates from the Picoazá-Megarok Basaltic quarry in Portoviejo and from the Ahon Mine in Quevedo, the purpose is to analyze and characterize the stone aggregates from the Picoazá Basaltic quarry and from the Ahon Mine to design concrete mixes and their impact on the performance for construction; an experimental methodology was applied. Samples were tested at the Soil Mechanics Laboratory of the Technical University of Manabi. Among the tests used were: angels machine, coarse granulometry, fine granulometry, specific weights, loose unit weights, unit weights, rodded unit weight, sulfate test, abrasion test, as well as the preparation of specimens to be tested to simple compression and to verify the resistances at ages of 7, 14, 21, 21, 28 days. Obtaining differentiated results, it is concluded that the aggregates of the Picoaza Megarok Basaltic quarry have greater resistance to compression in concretes than the Ahon Mine that come from a riverbed, these resistance drops of approximately 15% with respect
