CORROSION OF REINFORCEMENT

The co-operation of concrete and steel is based partly on the fact that concrete gives the reinforcement both chemical and physical protection against corrosion. The chemical effect of concrete is attributed to its alkalinity, which causes an oxide layer to form on the steel surface. This phenomenon is called passivation, as the oxide layer prevents propagation of corrosion. The concrete also provides the steel with a physical barrier against agents that promote corrosion, such as water, oxygen and chlorides. Read this topic

    Pdf 32 BSNL JTO 2006 Previous Year Solved Question Paper

    Q.1 A house served by a 220V supply light, is protected by a
    9-Ampere fuse. The maximum number of 60 W bulbs in parallel
    that can be turned on is
    (a) 11 (b) 33
    (c) 22 (d) 44

    Q.2 An n-channel JFET has IDSS = 1 μA & VP =5V. The maximum
    transconductance is
    (a) gm = 0.4 milli mho (b) gm = 0.04milli mho
    (c) gm = 0.04 mho (d) gm = 0.4 millimilli mho

    Q.3 The base to base resistance of a UJT is 6 K Ohm when the emitter
    current is zero. If B1 R = 3.6 K Ohm, the intrinsic stand off ratio is
    (a) n = 0.66 (b) n = 0.6
    (c) n = 6.0 (d) n = 3.6
