Cracks influence the durability of reinforced concrete (RC) structures in aggressive environments by accelerating ingress corrosive agents to embedded steel. This study investigated crack width (0·7 mm, 0·4 mm and incipient cracks), binder type (100% CEM I (ordinary Portland cement – OPC) 50/50 OPC/Corex slag blend), water-to-binder (w/b) ratio (0·40 0·55) reopening on chloride-induced corrosion RC specimens with constant cover 40 mm. Over period (31 weeks), rates varied from passive values...
Africa is urgently in need of adequate basic infrastructure and housing, it one the continents where massive construction activities are on rise. There a vast variety potentially viable resources for sustainable continents, consequently, continent can bring innovative, greener technologies based local sources effectively into practice. However, unlike established concrete constituents from industrialised countries global North, most innovation potentials African have not yet been focus...

The chloride conductivity index (CCI) is a quality control parameter used to assess the resistanc of concrete ingress. It determined from (CC) test which has been in use South Africa for close two decades. During this time, it undergone number changes improve on its robustness, reproducibility, and repeatability. Plans are now under way incorporate other durability tests (oxygen permeability water sorptivity) into SANS standards, important that end user aware why they were made....
The splash and spray tidal zones are generally assumed to be the most severe marine exposure environments with respect steel reinforcement corrosion in concrete structures. However, it has been observed several aged structures along Southern African coastlines, that there is usually relatively insignificant damage zone, despite very high (above-threshold) chloride contents. To develop a full understanding of severity conditions regard actual deterioration, imperative other factors directly...
