the recycled aggregate. The use of recycled aggregate generally increases the drying shrinkage creep & porosity to water & decreases the compression strength of concrete compared to that of natural aggregate concrete. It is nearly 10-30% as per replacement of aggregate. Recycling reduces the cost (LCC) by about 34-41% & CO 2 emission (LCCO 2

Use of recycled aggregates are required for sustainable developments as it conserves natural aggregates and reduces the space required to dispose demolition wastes. It also reduces consumption of energy. Recycling of concrete is economical as it …
The recycled concrete has a bulk density that is lower than the natural aggregate. Absorption and porosity of water: Water absorption occurs through two types of mechanisms: passive absorption and active absorption. This defines the water amount that is absorbed by the RCA concrete. The water absorption of RCA concrete is in the range of 5 and 6%.
The use of recycled concrete aggregates (RCA) form construction and demolition waste (C&DW) in construction, as an alternative to natural aggregates, has strong potential. The use of RCA preserves the natural resources and reduces the space required for the disposal of RCA in landfill.
Recycled concrete aggregate (RCA) are aggregates obtained by recycling clean concrete waste where content of other building waste must be very low – below few per cent. For instance, …
Making use of recycled aggregates over materials can save money as they are less expensive to produce. If recycled materials are available locally then this can reduce the cost of transporting the aggregates; Producing …
The Benefits of Recycled Concrete Aggregate Eco-Friendly – The most important advantage of using RCA is that it is a "green" construction material. The process of harvesting stone and then crushing it down to size requires the use of …
Utilising recycled materials instead of sending them to landfills helps you to avoid landfill tax, too. 2. It's durable Whilst recycled aggregate costs a fraction of the price of raw …
Utilising recycled materials instead of sending them to landfills helps you to avoid landfill tax, too. 2. It's durable Whilst recycled aggregate costs a fraction of the price of raw materials, no sace is made to its quality and performance. On its own, it appears to be just as strong as traditional aggregate and has a reliable structure.
Advantages of Recycled Aggregate Reduces the amount of aggregates to be created, hence less evacuation of natural resources. While …

The use of recycled concrete to produce recycled aggregate has the following advantages: Recycling construction waste at the demolition site can reduce construction and transportation costs, as well as energy use and road and equipment losses.
It has been estimated that recycling a single ton of cement could save 1,360 gallons of water and 900kg of C02. Construction Uses As a cheaper and more affordable alternative to new aggregate, crushed recycled concrete can be an invaluable tool when it comes to construction. But there are also other uses for the recycled chunks.
ADVANTAGES OF RECYCLING PLASTIC: • Protects Environment: The most important benefit of recycling is that it helps in protecting the environment in a balanced manner. For example, by using recycled paper, we can reduce deforestation to an extent. A number of other natural resources can be reused this way. • Reduces Energy Consumption: A large amount
Recycling of demolished concrete into aggregate is environmentally beneficial by preserving NA resources, by waste reduction and by preserving landfill space.
