Evaluation of Chloride Diffusion in Concrete Using Bulk Diffusion Test and Scanning Electron Microscopy
… implemented which involved the preparation and testing of 31 different concrete mixes, each incorporating varying proportions of SCMs and w/cm ratios. Concrete samples were mixed, poured, and cured according to ASTM standards and then subjected to exposure in an extremely aggressive environment …

Evaluation of surface treatments for RC structures failing to meet South African durability index requirements
… was not possible since modified and custom tests differing from the standard bulk diffusion test were used to evaluate performance. Chloride resistance was improved due to the pure silane however service life improvements could not be quantified. Unexpected failures occurred during the …

Assessment and prediction of chloride ingress and carbonation in patch repair mortars
… conductivity (Chloride Conductivity Index test) and rate of chloride-ion diffusion (bulk diffusion test), and (ii) gas permeability (Oxygen Permeability Index test) and rate of carbonation (accelerated carbonation test) in patch repair mortars. Eight mortar mixes were used in the …

Properties of Western Cape concrete with metakaolin
… analysis, ii) pozzolanic reactivity using three tests; strength activity index test, heat of hydration test (semi-adiabatic and isothermal calorimetry tests), and thermogravimetric analysis (TGA), iii) fresh properties of concrete assessed by setting time and workability, iv) hardened properties …

Service life extension of reinforced concrete structures using hydrophobic impregnation
… rate of 400 g/m2 . Several experimental tests were performed on untreated and silane treated concrete. Compressive strength and Durability Index (DI) tests were carried out to characterise the concrete mixes. Accelerated carbonation and moisture profiling tests were undertaken to assess …
