Rapid chloride permeability test as durability index of the concrete structure

Abstract

From the RCPT publication, this test has been frequently used in the concrete structures durability assessment. This test it could be determined in a relatively short time the material permeability, within a rank or quality level that allows comparing concretes as far as their characteristics. In this document, is present an intense investigation to evaluate mix designs with the principal objective to measure the participation and contribution of the components that take part in the concrete manufacture. A detailed review of the components contribution is applied to know specifically the properties in the product during any state: fresh or hard path. In this paper, are identified and included the most influence variables in the concrete properties modification.
