viii) Clause 5.4.7 This clause is deleted along with its sub-clauses ix) Clause 7.1.3.4
Replace this clause by clause as under: Sufficient spacers shall be provided as shall in the opinion of the Engineer be necessary to maintain specified concrete cover to the reinforcement and preventing displacement before and during the placement of the concrete. Spacers should be of such material and designs as will be durable, will not lead to the corrosion of the reinforcement and will not cause spalling of the concrete cover. Spacer block made from cement, sand and small aggregate should match the mix proportions of the concrete as far as is practicable with a view to being comparable in strength, durability and appearance.
