Aggregate Size In Concrete | Coarse Vs Fine Aggregate

03/02/2022· Coarse aggregate is any material whose particles are anywhere from 3/8 inches and 15 inches in width This is the size of aggregate often used in road construction Fine aggregate: Most fine aggregates consist of crushed stone or natural sand Most of the present particles must be able to pass through a 3/8inch sieve11/08/2018· Coarse aggregates are particulates that are greater than 95mm The usual range employed is between 95mm and 375mm in diameter Typically the most common size of aggregate used in construction is 20mm A larger size, 40mm, is more common in mass concrete Larger aggregate diameters reduce the quantity of cement and water neededDifferent Types & Sizes of Aggregate for Concrete
