to fine aggregates regarding their approval for use on highway construction projects are A5 approved for all uses. B5 approved for all uses where manufactured fine aggregate is allowed. G5 not approved. The A rating is for all natural sands. The B rating is for manufactured fine aggregates. Coarse Aggregates
Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates.

Aug 11, 2018 0183 32 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 needed because of its lower Voids. When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate.
Concrete is an erection material composed of cement, fine aggregates and coarse aggregates mixed with water. Portland cement is the mostly used cement for the production of concrete. It is the most popular artificial material. Probably It is used more than any other man made product in the world. Uses
