The amount of recycled coarse aggregate used in this research is approximately 125 kg. Many researchers state that recycled aggregates are only suitable for non-structural concrete application. This research, however, shows that the recycled aggregates that are obtained from concrete specimen make good quality concrete. The
using varying proportion of Recycled Concrete Coarse Aggregates (RCCA). Therefore, this research is focused on the effectiveness of using treated or recycled aggregates as a replacement for common aggregates to produce a pavement quality concrete structure as there is a lack of research done in
Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
Construction aggregate or aggregate is a broad category of coarse particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world. Crushed stone or Stone or more...
plastics were used to prepare the coarse aggregates thereby providing a sustainable option to deal with the plastic waste . There are many recycling plants across the world, but as plastics are recycled they lose their strength with the number of recycling. So these plastics will end up as earth fill.

giving infrastructural laws relaxation for increasing the use of recycled aggregate. This paper reports the basic properties of recycled fine aggregate and recycled coarse aggregate & also compares these properties with natural aggregates. Basic changes in all aggregate properties are determined and their effects on concreting
In general, the reuse and recycle of construction waste is concentrated in the preparation of recycled aggregate for concrete. By adding a portion of recycled aggregate instead of natural aggregate coarse into the mixture, producing the recycled concrete, which can conserve energy and materials for …
Mar 30, 2018· At this rate of use, there will be a critical shortage of NA in the future unless an alternative material for natural coarse aggregate is used. One source for alternative aggregate is recycled concrete aggregate (RCA) from construction and demolition waste.
Recycled Aggregate Concrete: Applications, Advantages & Disadvantages in Construction World is growing and urbanising at a very fast rate and so is India. This effect of rapid urbanization is also seen in construction industry.
coarse aggregate by demolished waste on workability and compressive strength of recycled concrete for the study at 7 and 28 d. The compressive strength thus, observed was compared with strength of ...
Investigations on Concrete with Recycled Concrete as Coarse Aggregate Muhammad Ali.K, Sankaranarayanan.K.M . Abstract:In India, a huge quantity of construction and demolition wastes are produced every year. These waste materials need a large place to dump and hence the disposal of these wastes has become a problem. Also the continuous use of
M grade concrete. e recycled coarse aggregates have been utilized as such (unwashed) as well as in washed form for comparison purpose with control concrete using natural aggregates. Engineering properties and durability aspects of the hardened concrete prepared with the replacement of natural aggregates with recycled aggregates are discussed. 2.
recycled concrete as coarse aggregate for the production of concrete. It is required to verify whether the recycled concrete aggregate is acceptable or not. Three types of aggregates are used in this project which includes natural coarse aggregate, natural fine aggregate and RCA. Natural coarse aggregate used is microtonalite with maximum size
Effect of Recycled Aggregates on Mechanical Properties of Concrete . Yamini Jayantibhai Patel . Abstract: Many structures that were constructed in India during the construction boom of the 1970s are now required of either major repairs or possible replacement. Also due to new construction for better economic growth, tructures are s
Aug 29, 2014· Over the last five years, India's first and only recycling plant for construction and demolition (C&D) waste has saved the already-polluted Yamuna and …
water cement ratio was kept constant for all the mixes. The coarse aggregate in concrete was replaced with 0%, 20%, 40%, 60%, 80% and recycled coarse aggregates. The test results indicated that the replacement of natural coarse aggregates by recycled aggregates up to 40% had little effect on the compressive strength, but higher levels of
coarse aggregates in high strength concrete mixes by 0, 10, 20, 30, 40 and 50% of recycled coarse aggregates. A 50% replaced mix with reduced w/c ratio was also tested. From the experimental investigation it was found that recycled coarse aggregates can be used for making high strength concretes by adjusting the w/c ratio and
The result of sieve analysis carried out as per IS 2386 for different types of crushed recycled concrete aggregate and natural aggregates. It is found that recycled coarse aggregate are reduced to various sizes during the process of crushing and sieving (by a sieve …
(10%, 20%, 30%) of natural aggregates in SCC with recycled coarse aggregates and the properties of SCC were evaluated. A comparison of SCC with concrete compacted using conventional method was also included in the study. The additive used in SCC for …
Moreover, the discussion about recycled aggregate usually correlate with recycled coarse aggregate. Coarse recycled concrete aggregate (RCA) is produced by crushing the demolition waste of at least 95% by weight of concrete, and having a total contaminant level typically lower than 1% of the bulk mass.
This study evaluated the use of recycled concrete as coarse aggregate in new concrete pavements. Recycled concrete aggregate (RCA) produced from demolished pavements in three geographically-dispersed locations in Washington state were used to perform testson aggregate characte ristics, fresh concrete propertiesand hardened concrete properties.

Present investigations deal with the development of green concrete (M 30 grade) using recycled coarse aggregates for sustainable development. Characterization of recycled coarse aggregates showed that physical and mechanical properties are of inferior quality and improvement in properties was observed after washing due to removal of old weak mortar adhered on its surface.
Abstract: The requirement of concrete aggregate in India is large. Corresponding to current annual production of cement of 300 million tonnes, total requirement of coarse and fine aggregate for use in cement concrete, mortar and plasters of about 1500 MT per year is a safe estimate.
The recycle coarse aggregate is one of the approaches towards this need. If the recycled coarse aggregate are used in conventional construction work it would saves the cost of materials. In this experimental study the natural coarse aggregate is replaced with recycled coarse aggregate at different percentage and the mechanical
