QUESTION ONE (1) The University of Zambia Council plans to build student hostels at a new location along Kamloops Road. On the project, the department of civil and environmental engineering has been engaged as a design consultant. Being a student in the department, you are tasked to carry out the concrete mix design for the structures. Design the concrete mix according to the following prevailing site conditions and requirements: Design Environment Bridge pier exposed to freezing and subjected to deicing chemicals: Required design strength = 24.1 MPa; Minimum dimension = 300mm; Minimum space between rebar = 64mm; Minimum cover over rebar = 64mm Statistical data indicate a standard deviation of compressive strength of 2.4 MPa is expected (on more than 30 samples). Also given that only air entrainer is allowed. Available Materials Cement: Select type V due to exposure Air entrainer: Manufacture specification 6.3 ml/1% air/100 kg cement. Coarse aggregate: 25 mm nominal maximum size, river gravel (rounded) = مدائن wo ³x wor] = (Vw x 100) Bulk oven-dry specific gravity -2.621, Absorption =0.4%, Oven-dry redded density = 1681 kg/m3, Moisture content = 1.5 % 2621kg/m² Fine aggregate: Natural sand Bulk oven-dry specific gravity =2.572, Absorption =0.8%, Moisture content = 4 %, Fineness modulus = 2.60. =2.60- [20]
