1.1.3.1 Behavior of water in concrete




                                                                                                               mixture





          • Role of water in concrete mixture:


                 a. To  enable hydration process


                 b. To lubricate the concrete mixture (gravel, sand and
                         cement) in order to facilitate placing


                 c.      To wash aggregates


                 d. For curing process


          • Potable water can be used in concrete mixing without

               testing its quality.


          • Natural water can be used will depend on the fitness of

               water without prior treatment.


          • Specification for test on water for making concrete can

               be obtained in BS 3148:1959 or MS 7.3:1971
