Formatted abstract
For this project, standard apparatus was set up to determine the bleeding rate of concrete in accordance with AS1012.6 - 1999. In addition, penetration tests were performed in accordance with AS1012.18 - 1996 to determine the setting time of fresh concrete. Two strength of concrete, 32 MPa and 50 MPa were tested with two different mix designs with and without retarder in the mix. The rate of bleeding and the rate of evaporation from the concrete are important to the behavior of concrete. Consequently, careful handling of cement paste, and the maintenance of constant temperature and relative humidity were required throughout the work. The measurement of the bleed water was very carefully to minimize the associated errors. Graphs were plotted to show the relationship between bleed and time, and factors that influence the bleeding of concrete were analyzed. The strength after 28 days was checked by testing standard cylinders of the concrete in compression.
