SLUMP MAINTAINED AFTER LONG INTERVALS
Posted by PRAJOT from MUMBAI, OT, IN on October 6, 2006
HOW DO WE ATTAIN 120 TO 150 MM SLUMP AT SITES WHICH ARE AT A DISTANCE OF 30 TO 35 KMS FROM THE PLANT WITHOUT SACRIFICING THE STRENGTH & WORKABILITY OF CONCRETE.
The best way to do this is to use a mid-range water reducing agent in the mix at the plant to establish an initial 100mm slump at the plant with the W/C slightly lower than specified. Then on site add a small amount of prescribed high-range water-reducing agent after dosing the small amount of yet-to-be-added water.
