Using the absolute volume method, design a suitable non air entrained concrete mixture. Structural design requires a 28-day concrete compressive strength of 28 MPa and a slump of 25 mm. The concrete is to be delivered from a well-established ready-mixed plant for which the standard deviation of similar concrete S = 1.49 MPa (based on 100 test results). Available local materials have the following properties: Coarse aggregates crushed aggregates Maximum size = 19 mm oven-dry relative density = 2.65 absorption (SSD condition) = 1.5% available materials has total moisture content = 1.0% oven dry rodded bulk density 1= 650 kg/m^3 Fine aggregate Well-graded natural sand oven-dry relative density = 2.60 absorption (SSD) condition = 0.5% available materials has total moisture content = 2.5% Fineness modulus = 2.8 Cement and concrete All types of cement have specific gravity of 3.15 Concrete non air entrained No durability problem
