Concrete durability index testing manual

This version of the Durability Index Testing Procedure Manual contains a number of new aspects. The most important is that Parts 1, 2, and 4 have been formalised as SANS Test Methods: SANS CO, SANS CO, and SANS CO, respectively. Part 3, the Water Sorptivity and Porosity Test Procedure must still be formalised . CONCRETE DURABILITY INDEX TESTING MANUAL PART 2: STANDARD PROCEDURE FOR OXYGEN PERMEABILITY TEST SCOPE This test method sets out the procedure for determining the oxygen permeability index as originally described by Alexander, Ballim and Mackechnie(1). The method described herein supersedes the version in ref. 1. the concrete durability index tests as originally described by Alexander, Ballim and Mackechnie (1). Where durability index results are required for concrete mix acceptance and mix design purposes, representative samples can be prepared from concrete cubes, cast in the laboratory. Where durability index results are required for.

This version of the Durability Index Testing Procedure Manual contains a number of new aspects. The most important is that Parts 1, 2, and 4 have been formalised as SANS Test Methods: SANS CO, SANS CO, and SANS CO, respectively. Part 3, the Water Sorptivity and Porosity Test Procedure must still be formalised through the SABS processes. Indexes from the DI tests are chloride conductivity index (CCI), oxygen permeability index (OPI) and water sorptivity index (WSI). The DI tests are described in detail by Alexander et al. [ 11 ]. Standard samples are 70 mm diameter, 30 mm thick concrete discs preconditioned in a 50°C drying oven for 7 days. CONCRETE DURABILITY INDEX TESTING PART 1: STANDARD PROCEDURE FOR PREPARATION OF TEST SPECIMENS SCOPE This test method describes how to cut and prepare test specimens to perform the concrete durability index tests as originally described by Alexander, Ballim and Mackechnie (1). Where durability index results are required for concrete mix acceptance and.

Summary: Durability of reinforced concrete structures is often dependent on the corrosion of reinforcement due to ingress of aggressive ions and fluids. This method describes how to cut and prepare test specimens to perform the concrete durability index tests, as originally described by Alexander, Ballim and. strength concrete in durability tests is limited.
