Basically in cement concrete we used 10mm to 20mm aggregate, And and PCC we may use 40mm rarely. In damp proof course we used 10 mm for better preventions again permeability and for slab, beam and column we use mixture of 10mm to 20mm. 40mm aggregate is used for PCC in foundation or base course in rigid pavement.

The use of lightweight aggregates reduces the bearing pressure and reduces the potential for failure. Similarly, the use of lightweight aggregates can significantly reduce the settlement of earth structures. Lightweight aggregate has been used as a structural fill in TensarTech reinforced soil walls to reduce settlement and improve performance.

Lime treated aggregate was sieved through 10 mm and 20 mm sieves and washed with clean water and oven dried subsequently for use in concrete mix design. The natural and recycled coarse aggregates were proportioned by replacing natural coarse aggregates at intervals of 10% by weight with recycled coarse aggregates in the M40 grade concrete.

Aggregate sizes up to 14 mm are common in single/single seals; 10 mm and 14 mm aggregate are usually used where there is sufficient traffic volume to warrant the use of large sized aggregates. For lower traffic volume roads and low speed environments, the use of 7 mm aggregate is often sufficient.

In the majority of concrete works, aggregate sizes of 20 mm or smaller are used. To ensure good coarse aggregate compaction and higher concrete density, it is recommended to mix 20 mm and 10 mm coarse aggregates in the ratio of 70:30 or 60:40. It is recommended to stack different aggregate sizes to use them efficiently. Prevent the use of ...
