ABSTRACT1ABSTRACT2

ABSTRACT

crushed bricks aggregate and recycled concrete aggregate with different percentages of replacement from aggregate (coarse fine). The effect of each type on the fresh and hardened properties of SCC has been studied. The fresh properties of SCC are measured by using Slump Flow, JRing Tests. While hardened properties included compressive strength, splitting tensile .

Recycled Aggregate1Recycled Aggregate2

Recycled Aggregate

Recycled aggregate comes primarily from PCC and AC from road rehabilitation and maintenance, demolition, and leftover batches of AC and PCC. After processing, the rocks retain bits of cement or asphalt. A roadway is built in several layers: pavement, base, and sometimes subbase. The pavement is the surface layer, and is made of PCC or AC.

Report of Recycled Concrete Aggregates

Summary Fresh concrete made with recycled aggregate tends to be very harsh due to the angular shape and rough surface of the aggregate, require higher water contents due to higher absorption capacity of the cement paste, higher air content due to greater porosity of the recycled aggregates themselves and to the entrained air in the original mortar than concrete made with aggregates. .

Recycled concrete will have a higher absorption and lower specific gravity than conventional aggregates. To produce good quality, durable concrete containing a portion of recycled concrete aggregate often requires trial concrete mixes and close monitoring of the properties of the old recycled concrete, with mix adjustments made, as needed.
