Coating concrete secondary containment structures exposed , swaziland reinforced concrete tank chemical volume

Concrete has traditionally been the material of choice for building secondary containment structures because it is relatively inexpensive and has structural properties which make it ideal for supporting the loads of vehicles and large tanks. However, concrete`s chemical properties make it susceptible to corrosion by some common fertilizers.AGGRESSIVE INFLUENCES OF WATER FROM reinforced concrete members is studied. Structural members exposed to wastewater environment are susceptible to different forms of chemical attack. Usually, concrete is resistant to most natural environments and many chemicals. Concrete is virtually the Septic Tank Guidelines - BVSDE Desarrollo Sostenible1. The walls of the tank can be made of poured, reinforced concrete, stone masonry, brick or concrete blocks. The tank should be made water tight with a 25mm coating of cement plaster, applied in two coats, in order to avoid infiltration around the tank and maintain and anaerobic space. For small tanks the floor need not be reinforced.
