Calculation of bricks in 1 brass

Image
In this article you will get "How to calculate bricks in 1 brass"                       BRICKS IN 1 BRASS 1 brass = 2.83 cubic meter How it's come?       1m³ = 1 m x 1 m x 1 m                = 3.28084 x 3.28084 x 3.28084                = 35.315 cft               (1 meter = 3.28084 feet) As we know,       1 brass = 10 ft x 10 ft x 1 ft = 100 cft Therefore,       1 brass = 100/35.315                     = 2.83 cubic meter ( proved) We take standard size of brick;            10 cm x 10 cm x 20 cm Now convert "cm" in to "m",  we get,             0.1 m x 0.1 m x 0.2 m = 0.002 cubic meter Now calculate no.of ...

Things Site Engineer Must Know about Reinforcement and Steel Bars

Image
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.
