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).
13 May 2014 mechanical, and durability tests were conducted in the laboratory to characterize the properties of the local cementitious mineral admixtures, cement mortar and portland cement concrete mixtures containing these admixtures. The results from this study indicated that the sulfate resistance of concrete was

Four international durability testing procedures have been eva- luated in this study. It has been shown that durability performance of existing structure is different than the performance of concrete prepared in test samples whether these samples are prepared at site or at the lab due to the differences between the preparation
various replacement level of manufactured sand were studied and the optimum replacement level was found to be the concrete containing 70% manufactured sand blending with 30% natural sand. So in this chapter the following tests are carried out for assessing the durability properties of mortar and concrete with 100%
Experimental techniques for measuring progressive deterioration of concrete were investigated. Specimens of pastes, mortars, and concretes were subjected to alternate wetting and drying in sodium sulfate solutions and plain water as well as freezing and thawing. The methods used to assess the effects included: changes
(2004) established a testing regime to optimize the strengths and durability characteristics of a wide range of high-performance concrete mixes. The intent of the selected designs was to present multiple solutions for creating a highly durable and effective structural material that would be implemented on Pennsylvania bridge
production of durable concrete through materials selection, proportioning, construction practices, specifications, and testing. Also included is a section of case studies, providing examples of problems encountered in the field that involve concrete pavement and bridges, along with the proposed solutions by the authors of the
