idotillinoisgov, For fine aggregates, the fineness modulus ranges from 200 to 400, while coarse aggregates range from 650 to 800, when all material is finer than 1-1/2 in (381 mm) Combined gradations will range from 400 to 700What is the effect of coarse aggregate size in compressive ,, Since 20 mm is commercially available, and we cannot use 40 mm for slabs below 200 mm thickness, we usually use 20 mm coarse aggregate in all the designs If the max size of aggregate is greater than 1/5th of the least dimension, the chances of failure in shear are extremely high20, 20-5mm Shingle Click here for CE information Available from our Gill Mill & Duns Tew quarries, the 20-5mm Limestone Shingle is commonly used for ready mixed & precast concrete, driveways, footpaths, drainage, pipe bedding and landscapingAggregates for Concrete, The important characteristics of aggregates for concrete are listed in Table 5-2 and most are discussed in the following , No 8 475 mm No 4 125 mm 25 mm 375 mm , Percent passing, by mass 100 80 60 40 20 0 Fine aggregate Coarse sand Fig 5-6 Curves indicate the limits specified in ASTM C 33 for fine aggregate and for one ,Civil Work, Civil Work Sp S on S so S red S October 20, 2014 CONCRETE GRADE: M5 = 1:4:8 M10= 1:3:6 M15= 1:2:4 M20= 1:15:3 , 3RAFT FOUNDATIONBOTTOM/SIDES : 75 mm 4STRAP BEAM : 50 mm 5GRADE SLAB : 20 mm 6COLUMN : 40 mm 7SHEAR WALL : 25 mm 8BEAMS : 25 mm 9SLABS : 15 mm 10FLAT SLAB : 20 mm 11STAIRCASE : 15 mm 12RET WALL : 20/ 25 mm ,.
