Recycling of Concrete (Recycling Coarse Aggregate)

Recycling of Concrete (Recycling Coarse Aggregate)

It has been observed that the recycled coarse aggregate is used as normal aggregate. The workability of the concrete is increased by using RCA. Maximum properties of Recycled coarse aggregate have shown good with a little variation. Recycled aggregate materials produce harsh mixes with lower workability than Natural aggregates. New standards should be introduced for recycled aggregates so

Recycling of Brick Aggregate Concrete as Coarse Aggregate

Recycling of Brick Aggregate Concrete as Coarse Aggregate

Abstract. An extensive investigation was carried out for recycling of demolished brick aggregate concrete as coarse aggregate. For this, demolished concrete blocks were collected from 33 different building sites of different ages and broken into pieces as coarse aggregate. Owing to the lack of availability of stone aggregate in Bangladesh, most of the old structures are constructed with brick chips as coarse aggregate, therefore the recycled aggregate
