What is your recommendation for the maximum size of coarse aggregate for the following situation? A continuously reinforced concrete pavement cross section contains a layer of No. 6 reinforcing bars at 6-in. centers, such that the steel is just above mid-depth of a 10-in. thick slab. Cover over the top of the steel is therefore about 4 in.

What is your recommendation for the maximum size of coarse aggregate forthe following situation? A continuously reinforced concrete pavement crosssection contains a layer of 19-mm reinforcing bars at 150 mm. centers, suchthat the steel is just above mid-depth of a 250 mm. thick slab. Cover over thetop of the steel is therefore about 100 mm.

Concrete is required for several structural members of a residential house. Due to the present moisture, it is expected that the concrete shall be non-aerated (Non AE) with a 28 day compressive strength of 3.000 psi for slabs and 4,000 psi for beams and columns. Due to extra moisture present in the site, the slump to be used shall be the minimum allowed by the ACI mix. Using a 3/4 inch max aggregate size, compute for the weight of cement, water coarse aggregate, and fine aggregate. Aggregate details: Cement: Type 1. Specific Gravity = 3.15 Coarse Aggregate: Bulk Specific gravity (SSD) = 2.65; absorption capacity = 4%. Dry-rodded unit weight= 100 lb/ft: surface moisture 1.2% Fine Aggregate: Bulk Specific Gravity (SSD) = 2.60: Absorption capacity = 1.5%: Fireness modulus = 2.70: Surface moisture= 496 Structural members dimmensions: Columns: 8 pes 300mm x 300mm x 3100mm (Length x Width x Height) Beam: 9 pcs. 300mm x 500mm x 4000mm (Length x Width x Height) Slab: 12000mm x 4000mm x 400mm…
