Things Site Engineer Must Know about Reinforcement and Steel Bars

There are some important things site Engineers must know about reinforcement and Steel Bars are as follows;

       THINGS SITE ENGINEERS MUST KNOW            ABOUT REINFORCEMENT AND STEEL BARS

● Hooks for stirrups is 9D for one side.
● No.of stirrups = (clear span/spacing ) + 1
● For cantilever Anchorage length for main steel is 69D.
● 'L' for column main bar in footing is minimum length 300mm.
● For chairs in footing minimum 12mm dia with 1m spacing should be used.
● Lapping of steel bar should not be used for larger than 36mm.
● In steel Reinforcement binding wire required 8kg per MT.
● Weight of rod per meter = D^2/162, (D=dia of bar).
● Main bar in the slab shall not be less than 8mm (HYSD) or 10mm (plain bar).
● Distribution bar in the slab shall not be less than 8mm and not more than 1/8 of the slab thicknes.
● All reinforcement shall be free from loose rust, oil or any other substances.

How to calculate quantity of Cement and Sand in Plaster

How to calculate quantity of Cement and Sand in Plaster? Ex:    Area of plaster = 100 ft × 100 ft    Thickness of plaster = 12mm Step 1) find out volume of plaster:  (Need to all units that is "ft" and "mm" convert into "m" )                   1000mm = 1m So that;        12mm = 0.012m                      3.28ft = 1m So that;        100ft = 30.49m     Volume of plaster = 30.49 × 30.49 × 0.012                                      = 11.15 m³ Step 2) Convert plaster volume wet to dry:              Take 33%     Dry vol = 11.15 × 1.33                   = 14.83 m³ Step 3) Consider wastage:               Take 5%      Total dry vol = 14.83 × 1.05                             = 15.57 m³ Step 4) find out Cement and sand required:               Take;                    Cement : sand                               1 : 6     Cement req = 1/(1+6) × 15.57                           = 2.22 m³             Need to cement in bags
