Characterization of Recycled Aggregate Concrete

Dec 13, 2014· The coarse recycled concrete aggregate (RCA) used in this investigation was sourced from the tested concrete specimens like cubes, cylinders, prisms and beam specimens originally tested for various purposes in the concrete testing laboratory of IIT Roorkee Total six numbers of concrete mixtures were prepared.

PROPERTIES OF RECYCLED AGGREGATE CONCRETE

properties of recycled aggregate are much more pro-nounced than as is the case with natural aggregat Figure 2 Appearance of the recycled aggregate grains [2] 21 Aggregate grading Grading of recycled coarse aggregate normally satisfies the standards for natural aggrega-te, while in the case of recycled fine aggregate.

Experimental Studies on High Strength Concrete by using

coarse aggregates in high strength concrete mixes by 0, 10, 20, 30, 40 and 50% of recycled coarse aggregat 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.

Conclusions and Recommendations

The vacuum-drying method using the CoreDry device was promising, but it was not able to completely dry highly absorptive materials such as BF slag coarse aggregate and recycled concrete The results of Experiment 4 showed that testing the aggregate in its in-situ moisture condition was a better alternative to the standard oven-drying method.

Use of Recycled Tires as Partial Replacement of Coarse

fuel, the most promising use of recycled tires is in engineering applications as artificial reefs, erosion control and aggregates for asphalt and concrete The use of recycled tire rubber as partial aggregate in concrete has great potential to positively affect the properties of.

Effect of Recycled Coarse Aggregate on Concrete Properties

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.
