Transcribed Image Text:Q1: Prepare mix design for given data
• The 28-day compressive strength should be 34 MPa, The slump should be between 75 mm and 100 mm
and the maximum aggregate size should not exceed 19 mm The properties of the materials are as follows:
• Cement : Type I, specific gravity = 3.15
• Coarse Aggregate: Bulk specific gravity= 2.65; absorption capacity = 0.5%; dry-rodded unit weight = 1605
kg/m3, surface moisture = 1%
• Fine Aggregate: Bulk specific gravity= 2.60; absorption capacity = 1.1%; fineness modulus = 2.70; surface
moisture = 3%
