CONSTRUCTION OF WIRE-REINFORCED CEMENT MORTAR TANKS

The mix generally used for concrete works in water retaining structures is 1 : 1.5 : 3 (20mm). However for the floor concrete in these tanks 1:2:4 (20mm) concrete would suffice. This is possible as all internal facets of the tanks are being rendered and finished water tight using neat cement finish.
