Task 3 Follow the Australian Standards and relative code to design and calculate the following two concrete mix to achieve the design requirement. 1. Determine the mass of water, cement and aggregate required for the following mix of a simple supported RC beam and tabulate the trial mix. ● Characteristics strength 40 MPa after 28 days. ● Crushed Coarse aggregate (10 mm and 20 mm specific gravity 2.7) Fine aggregate (River sand, FM = 2.5) ● GP cement 60 mm slump 2. Determine the mass of cement, water, fine aggregate and coarse aggregate required for the following mix for the RC beam shown in following drawing. Characteristics strength is 40MPa at 28 days. 35 number of specimens in the test sample Coarse aggregate (10 mm,20 mm and 40mm specific gravity 2.7) Fine aggregate (River sand, FM = 2.6) GP cement 45 mm slump Specific gravity of combined aggregate = 2.65 800 4N24 bars 350 N12 ligs w* Span - 7 m
