Checklist before Laying Cement Concrete

There are many precautionary measures before you lay cement concrete for any good construction. Make sure form work /shuttering for line, level and its strength. Steel bars and their placing should be checked. Ensure that there is proper cover to steel bars and adequate numbers of sports/chairs under crank bars. The planks or plates provided for walking over reinforcement are not disturbed during working.



Electrical pipes, fan boxes etc. are laid before lying cements concrete. The gap in shuttering plates is sealed properly by jute bags /mortar /rubber etc. and shuttering plates are properly oiled. Proper curing must be ensured after laying RCC slab. Raw materials should be of good quality and sufficient in quantity. The arrangements are taken in advance in case of rains etc.

Precautions for Steel Bars in RCC Work

All finished steel bars for reinforced work are neatly rolled to the dimension and weights as specified. They are sound, free from cracks, surface flaws, laminations, rough, jagged and imperfect edges and other defects. The bars are clear, free from loose mil scales, dust and loose rust coats of paints, oil or other coatings which may destroy or reduce bond strength.

They are stored in such a way as to avoid distortion and to prevent deterioration and corrosion. The steel bars are not cleaned by oily substance to remove the rust. The bar is bent correctly and accurately to the size and shape as shown in drawings. If possible, the bar of full length is used.

Quality of Finished Medium Tensile Steel

The finished medium tensile steel should be fine and be rolled cleanly to the dimension and should have weight as specified by BIS subject to permissible tolerance.

The finished material should be free from cracks, surface flaws laminations, rough and imperfect edges and other harmful defects. Steel section should be freeing from excessive rust, scaling and tilting and be well protected. Let’s find out more tips on specification of steel.
