The products includes five series: crusher, sand making machine, powder grinding mill, mineral processing equipment and building materials equipment.5 mm single size aggregate,The gradation of the coarse aggregates used in concrete pavement and concrete base shall meet the requirements for 37.5 mm and 19 mm aggregate shown in Table 4. Aggregates shall be stockpiled as individual size fractions and blended in the mix so as to meet the combined gradation requirements shown in Table 4..
Mar 162017 Gap-graded mixes contain aggregate retained on a 19mm or 37.5mm sieve Fines passing the No. 4 sieve (4.75mm) Used to obtain uniform textures for exposed-aggregate concrete

Aug 112018 The usual range employed is between 9.5mm and 37.5mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size40mmis more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed because of its lower Voids. When the aggregate is sieved through 4.75mm sieve
Crushed aggregate is produced by crushing quarry rockboulderscobblesor large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbasessoil-cementand in new concrete. After harvestingaggregate is processed: crushedscreenedand washed to obtain proper cleanliness and gradation.
Generally the size of coarse aggregate used is 10-12.5 mm. If we use the proportional mix of different sizes small to large ( 4.5 mm to 2025 mm)this make the concrete structure compact by align
Coarse Aggregate is normally greater than 5mm. Fine Aggregate is aggregate less than 5mm. Can be a single sized material typically 20mm14mm10mm,or 7mm or a graded aggregate consisting of a blend of single sized aggregate. Concrete Aggregates are produced to Australian Standards (AS 2758) or to more specific customer requirements.
