Análisis comparativo del concreto de una resistencia a la compresión f’c=240 kg/cm2, en base a cuatro cementos comerciales tipo GU para las fuentes mineras SOMIGU y ROOKAAZUL del Ecuador

Abstract

The study compares the behavior of concrete with compressive strength f'c = 240 kg/cm2, using four brands of GU cement (Atenas, Guapan, Holcim, Chimborazo) and aggregates from two Ecuadorian mining sources (SOMIGU and RooKaazul). Physical-mechanical properties of the concrete were evaluated following NTE INEN, ACI and ASTM standards. The results show that Atenas and Holcim cements exceed the designed strength, while Guapan and Chimborazo meet the specification.
