Caracterización de los agregados de las canteras megarok, (cantón portoviejo) y chorrillo (cantón montecristi), utilizados para mezclas de hormigón

Abstract

The purpose of this study was to investigate degree in both quarries Portoviejo and Montecristi, characterization and unlike the aggregates used for concrete mixes. Megarok (Portoviejo) and Chorrillo (Montecristi) was selected quarries. The guidelines of ASTM C136, ASTM C29 standards were followed. AASHTO T85, for testing aggregates, we also rely on the AC1 318 standards for the design of concrete and ASTM C39M for compressive strength of concrete. The wear test sulphate coarse aggregate of the two quarries above was further performed is an important parameter since many sulphates present in soil and water can attack and destroy the concrete was not well designed, we are governed us ASTM C88 standard.
