IJESRT INTERNATIONAL JOURNA Study on the use of Recycled Aggregate in concrete

re area. In order to reduce the usage 99), Stone says that the 10mm recycled aggregate and blended stated that the use of recycled aggregate for the construction and rehabilitation of local government roads has a great improve in the last five years. C & D Recycling Industry (n.d.), the fact file stated that from the time of the Romans, the stones from the previous roads were reused when rebuilding their vaunted set of roads. It also stated that since the end of world war two, the recycling industry had been well established in Europe. According to Seecharan (2004), the Detroid News stated that in 1980s, the old concrete crushed into a powder was a popular road builder at Michigan, USA.In 2002, Poon, et al [1] found that the replacement of coarse and fine natural aggregates by recycled aggregates at the levels of 25 and 50% had little effect on the compressive strength of the brick and block specimens, but higher le replacement reduced the compressive strength. However, the transverse strength of the specimens increased as the percentage of replacement increased. They also found that the replacement of natural aggregates at the level of up to 100%, concrete paving blocks with a 28-day compressive strength of not less than 49 MPa can be produced without the incorporation of fly ash, while paving blocks for footway uses with a lower compressive strength of 30 MPa and masonry bricks can be produced with the incorporation of fly ash. In 2002, Jose and Gomez-Soberon [2] found the result of Porosity of recycled concrete with substitution of recycled concrete aggregate. Experimental analysis was done with the samples of -9655 [136-142] ctions and
