Gradation and Size Pavement InteractiveHOW COARSE AGGREGATES AFFECT MIX DESIGN
The particle size distribution or gradation of an aggregate is one of the most influential aggregate characteristics in determining how it will perform as a pavement materialMaximum size of coarse aggregate Maximum size of aggregate affects the workability and strength of concrete It also influences the water demand for getting a certain workability and fine aggregate content required for achieving a cohesive mix For a given weight higher the maximum size of

Calculate cement sand and aggregate Civil RnDWhat s the best size of coarse aggregate in concrete in
Following is a simple method used by engineers to calculate cement sand and aggregate in volume cubic metre and in weight kg to produce nominal mix concreteGenerally the size of coarse aggregate used is 10 125 mm If we use the proportional mix of different sizes small to large gt 45 mm to 20/25 mm this make the concrete structure compact by align themselves in voids depending upon their size and compact mass will be formed with increased strength
