Types and Causes of Concrete Deterioration
Corrosion is an electrochemical process involving the flow of charges (electrons and ions). Fig. 3 shows a corroding steel bar embedded in concrete. At active sites on the bar called anodes iron atoms lose electrons and move into the surround-ing concrete as ferrous ions. This process is called a Types and Causes of Concrete Deterioration

Rapid Sand Filtration SSWMFind tools for sustainable
Rapid sand filtration in contrast to slow sand filtration is a purely physical treatment process. As the water flows through several layers of coarse-grained sand and gravel relatively large particles are held back safely (DIJK OOMEN 1978). However RSFs never provide safe drinking water without adequate pre-treatment and final disinfection.
