Most Important Practical Knowledge for Civil Engineer

There are some Useful points-

Least thickness of slab is 125 mm.
The dimension tolerance for cubes + – 2 mm.
Minimum compressive strength of Bricks is 3.5 N /mm2
Maximum Free fall of concrete allowed from the height of 1.50 m.
In soil filling as per IS code for every 100 sq-m 3 sample for core cutting test should be taken for experiment.
Electrical conduits shall not run in column for any structure.
Earth work excavation for basement above 3 m should be ventured frame.
Any inlaying will be compacted 95% of dry thickness at the ideal dampness content and in layers not more than 200 mm for filling above structure and 300 mm for no structure.
A set of 3D square tests will be done for every 30 cum of cement/every dimension of throwing/each cluster of bond.
Water bond proportion for various evaluations of cement will not surpass 0.45 for M20 or more and 0.50 For M10/M15 contractual worker.
For solid evaluations M20 or more affirmed admixture will be utilized according to blend structure necessities.
Cement will be put away in dry places on a raised stage about 200mm above floor level and 300mm far from dividers. Packs to be stacked not in excess of 10 sacks high in such a way, to the point that it is enough shielded from dampness and sullying.
Samples from crisp cement will be taken and no less than a lot of 6 solid shapes of 150mm will be arranged and relieved. 3 Cubes each at 7 days and 28 days will be tried for compressive quality. The test outcomes ought to be submitted to build for endorsement. On the off chance that outcomes are inadmissible important activity/amendment/healing measures must be worked out.
Water utilized for both blending and restoring will be spotless and free from harmful measures of oils, acids, alkalies, salts, sugar and natural materials or different substances that might be malicious to cement or steel. The ph will be for the most part somewhere in the range of 6 and 8.
