Calculation of Lap length in Reinforced Concrete

Nov 13, 2017Lap length for concrete of 1:2:4 Nominal mix: The Lapping length in tension (MS bar – mild steel bar) including anchorage value is 58d. So eliminating the anchorage value, the lap length = 58d – 2*9d = 40d. (Where 9d = hook allowance up to 25 mm and k=2) Lap length for M20 concrete: Columns – 45d; Beams – 60d; Slabs – 60d Get price

How Much Should Concrete Fall?

But the reason for including any fall, rather than making the surface level, is to allow the concrete surface to drain. Generally, using 1/8-inch fall—which is 1-1/4 inch per 10 feet—works well on larger surfaces like driveways and patios, but it requires good screed, bullfloat, and finishing operations to minimize water puddling (birdbaths).

Water–cement ratio

The water–cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. A lower ratio leads to higher strength and durability, but may make the mix difficult to work with and form. Workability can be resolved with the use of plasticizers or super-plasticizers.. Often, the ratio refers to the ratio of water to cementitious materials, w/cm. Cementitious Get price
