1) As per IS: 456 - 1978, the pH value of water shall be not less than 6 . 2) Spacing of stirrups in beams of effective depth’d’ should not be more than 0.75d or 300 mm , whichever is less. 3) In a singly reinforced beam, the effective depth is measured from its compression edge to the centroid of the tension reinforcement . 4) An R.C.C. roof slab is designed as a two-way slab if the ratio of longer span to shorter span is less than 2 . 5) The value of the maximum strain in concrete under bending compression in outermost fibre, as per IS 456:2000 (Limit State Method), is 0.0035 . 6) The minimum headroom over a stair must be 2.2 meters . 7) An R.C.C. column is treated as long if its slenderness ratio is greater than 12 . 8) The toe projection of foundation slabs is taken as minimum 150 mm or 1/5th of the depth of foundation , whichever is more (depends on site conditions, often approx. 1/3rd to 1/5th of...
