CE Quiz 32

The main reinforcement of an RC slab consists of 10 mm bars at 10 cm spacing. If it is desired to replace 10 mm bars by 12 mm bars, then the spacing of 12 mm bars should be

The purpose of transverse reinforcement in a slab is to

The overall thickness of RCC slab is 75 mm. The maximum diameter of the reinforcement bar that can be used is:

 A one-way RCC slab of 5 m span is provided with 10 mm diameter tensile steel bars at 100 mm c/c spacing. At what spacing should the bar be spaced if 12 mm diameter bars are used?

An RCC slab simply supported at two ends has a clear span of 3 m. The width of the support is 300 mm and the effective depth of the slab is 100 mm. As per IS 456:2000, the effective span of slab is:

The position of main reinforcement in a simply supported lintel has to be:

Shrinkage In concrete slab causes

For slabs spanning in two directions for calculating the span to effective depth ratio

The effective width of a column strip of a flat slab is

The minimum clear covers (in mm) to the main still bars in slab, beam, column and footing are respectively (consider slab, beam, column and footing are subjected to mild condition)
