Concrete cover for steel bar is much necessary to protect the steel against corrosion (rusting) and to provide resistance against fire. If fire occurs in the building, the steel might lose so much strength to impair its reinforcing effect and the beams might collapse. For Slab, the cover should be 15 mm.

Oct 10, 2017· Durability of concrete can be achieved by the use of proper quality of cement and aggregate and it can be made water tight by reducing the extent of pores in it. This is achieved by proper compaction. The quantity of water required for chemical action with cement is about 30% by weight. The extra water used is evaporated leaving pores in the concrete.

ROLLER COMPACTED CONCRETE DAM AND UTILIZATION OF FLY ASH IN JAPAN Kimitaka UJI1 SUMMARY RCC Dams have been constructed in order to reduce the construction period and construction cost due to the decrease of cementitious materials. Fly ash is important material for RCC Dam, and usually replaced from 20 to 30 % for cement.

Dec 04, 2013· The ABCs of RCC. Compressive strength, at the age of 28 days, as high as 40 MPa (6,000 psi) is common, and the 28day flexural strength can be MPa (800 psi) or greater. It's been shown that RCC pavement compacted to 96 percent of maximum density is more than twice as strong as the same mix compacted to 86 percent.
