What is Hacking?
As Per SP-27-1987-The roughing of solid backgrounds,
by hand or mechanical methods, to provide a
suitable key.
WORKABILITY OF CONCRETE - AS PER IS-456-2000
WORKABILITY OF CONCRETE - AS PER IS-456-2000 The concrete mix proportions chosen should be such that the concrete is of adequate workability for the placing conditions of the concrete and can properly be compacted with the means available. Placing Conditions Degree of Workability Slump(mm) Blinding concrete; Shallow sections & Pavements using pavers Very low In the ‘very low’ category of workability where strict control is necessary, for example pavement quality concrete, measurement of workability by determination of compacting factor will be more appropriate than slump ( see IS 1199 ) and a value of compacting factor of 0.75 to 0.80 is suggested. Mass concrete, Lightly reinforced sections in slabs, beams, walls, columns, Floors; Hand placed pavements; Canal lining; Strip footings Low 25-75 Heavily reinforced sections in s...
