Aggregates for Concrete - GreenSpec

Recycled concrete can be used as aggregate in new concrete, particularly the coarse portion. When using the recycled concrete as aggregate, the following should be taken into consideration: • Recycled concrete as aggregate will typically have higher absorption and lower specific gravity than natural aggregate and will produce concrete with slightly higher drying shrinkage and creep.

Aggregate in Concrete - The Concrete Network

Exposed-aggregate concrete pavement. Both gravel and crushed stone produce quality concrete. Gravel will have a lower water demand compared to crushed stone. Gravel is preferred for exposed-aggregate concrete in walkways and decorative applications. Crushed stone will usually exhibit a higher paste-aggregate bond.

Recycled aggregate concrete from large-scale

30-11-2020  This study shows that RCA has significant potential of using as substitution of natural aggregate in the production of concrete of 25 and 32 MPa compressive strength. Furthermore, RAC shows a higher rate of compressive strength development after 28 days of curing and results in comparable long-term compressive strength to conventional concrete.

Different Types Sizes of Aggregate for

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.

Maintaining proper aggregate stockpiles

“You have your best practices in place and try to produce the material with a certain amount of degradation built in,” he said. “The less you move material, the less expense is in it.” Degradation arises with marginal aggregates that break down after stockpiling, Buchanan said.
