Assignment Help Civil Engineering
Reference no: EM13564896

Design a non air entrained concrete mix using a maximum aggregate size of 27mm to be used for an interior beam having a 28-day compressive strength of 35 MPa (specified strength based on cylinder). The material properties are as follows:

Cement: All types have a specific gravity of 3.15

Coarse aggregate: Bulk specific gravity (SSD) = 2.9, absorption capacity = 0.5%, effective absorption = 0.3%, and dry-rodded unit weight = 1700 kg/m3

Fine aggregate: Bulk specific gravity (SSD) = 2.75, absorption capacity = 1.0%, surface moisture = 2.8%, and fineness modulus = 2.8

Use the upper value of the recommended slump range. Present the results based on given moisture contents.
