The recycled aggregate was manufactured by grinding the CDW in a jaw crusher and mechanical sieving, after which the waste was classified and split into coarse and fine aggregate. Table 1 shows the characterization test results of the fine recycled aggregate (FRA) and coarse recycled aggregate (CRA).
Crushing concrete allows us to produce our own DOT Certified RCA (Recycled Concrete Aggregate), a highly compactable base material. RCA is a great base for roads, driveways, trenches, walkways and sheds etc. RCA is roughly half the price of stone products purchased from a quarry and can be picked or delivered from our facility.
The recycled aggregate strength is enhanced by separating the attached mortar from the recycled aggregate after RA treatment with soaking and mechanical grinding processes. Following the crushing value of untreated RA, the crushing value of RA is improved by 28.64%.
However, during mechanical grinding recycled concrete aggregate could be damaged (micro – cracks by grinding). Autogenous cleaning [2] - with this process RCAs are placed in a rotating mill drum and collide against each other while removing pieces of attached mortar. The mill drum,
Grinding Method For Recycled Aggregate. The freezingthawing resistance of concrete made with recycled aggregate from nonairentrained concrete was the other hand if the original concrete was airentrained the ement of recycled aggregate heating and grinding method demolished concrete is heated in furnace tower up to 300c for 40 to 60 min which
Studies on recycling of deconstruction concrete into new concretes show that it is difficult to integrate fine recycled concrete aggregates in new concrete due to the high proportion of cement paste in the fine fraction which is porous and absorbs a lot of water. A way to upgrade this fraction is to use it in ground form as a main constituent of cement. Four types of fine recycled concrete ...

3. Removal of adhered mortar. Mechanical grinding, pre-soaking in water/acid are the common methods to remove the adhered mortar. Mechanical grinding is a popular treatment because of the simple procedure to produce high quality RCA (Sun and Xiao, 2004).However, mechanical grinding could easily damage RCA due to collision and grinding by introducing micro-cracks.

In this paper, a comprehensive literature review was conducted on the utilization of recycled concrete aggregate (RCA), which is the dominant construction and demolition waste material, in base and subbase layers and its comparison with natural aggregate (NA).
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
