Concrete recycling - Wikipedia

Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. The process involves crushing the rubble and sorting the pieces by size. The resulting aggregate can be used for revetments, road gravel, retaining walls, landscaping gravel, or raw material for new concrete.

Aggregates - Portland Cement Association

Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in ...

Use of RECYCLED AGGREGATES In CONCRETE- A …

Since the enormous quantity of concrete is available for recycling from demolished concrete structures, field demolished concrete is used in the present study to produce the recycled aggregates. The concrete debris were collected from different (four) sources with the age ranging from 2 to 40 years old and broken into the pieces of approximately 80 mm size with the help of hammer & drilling ...

Aggregates for Concrete - GreenSpec

Shear strength of recycled aggregate concrete is lesser than of normal concrete. This is because the recycled aggregate from field-demolished concrete for example can be relatively weaker than a typical natural aggregate. In general, there is a 10% decrease in strength when recycled coarse aggregates are used. Uses of Crushed Concrete Aggregates

Aggregate in Concrete - The Concrete Network

Special Considerations for Exposed-Aggregate Concrete. Contractors placing decorative exposed-aggregate concrete, where appearance is a prime concern, should pay special attention to the aggregate shape, texture, color, and overall appearance to yield the best looking final product (Photo 8). When placing architectural concrete, you should test trial mixes and place mock-ups to ensure that all ...

Use of waste plastic in concrete mixture as …

Pezzi et al. (2006) used plastic material particles incorporated as aggregate in concrete and evaluated the chemical, physical, and mechanical properties. The results proved that the addition of polymeric materials in fractions ⩽10% in volume inside of a cement matrix does not imply a significant variation of the concrete mechanical features. Marzouk et al. (2007) studied the use of consumed ...

Different Types Of Aggregate And Their Uses

The Different Types Of Aggregate. The categories of aggregates include gravel, sand, recycled concrete, slag, topsoil, ballast, Type 1 MOT, and geosynthetic aggregates (synthetic products commonly used in civil engineering projects used to stabilise terrain). Let’s detail a few of them. Crushed Concrete

Recycled Concrete Aggregates | Recycling …

Recycled concrete aggregate is aggregate made from used concrete from demolition sites. The quantity of old concrete from a demolition site depends on the type of building. For example, the list below shows the percentage of concrete for various building types. …

Perlite Use: Lightweight Insulating Concrete …

When used as the primary aggregate in concrete, expanded perlite provides several key advantages to the construction and precast manufacturing applications. Though lightweight perlite concrete is not usually suited for structural or load bearing uses, in other applications it provides improvement in load stress, noise reduction, thermal transfer resistance, and fire rating. Generally speaking ...

Uses of Aggregates - CEMEX USA - CEMEX

Concrete aggregates are composed of geological materials such as gravel, sand and crushed rock. The size of the particles determines whether it is a coarse aggregate (e.g. gravel) or a fine aggregate (e.g. sand). The resulting concrete can be used in its natural …

Use of sea sand as fine aggregate in concrete …

Chloride in concrete could be from cement, aggregates, water and even from the admixture. It is the overall effect that is important and not the fine aggregate alone. Chloride content not only corrodes the reinforcements in concrete but also causes efflorescence due to oozing out of salts from the concrete. Hence, chloride content needs to be controlled within limits.

Aggregate: Mechanical Properties of Aggregate | …

While using aggregate in the concrete, water on the surface of the aggregate should be taken into account, as it will contribute to the water in the mix and will affect the water-cement ratio of the mix, causing lower strength of the concrete. It is difficult to measure surface water of the aggregate. Therefore its value may be assumed according to I.S. 456, 1964 given in Table 4.12.
