Investigations on Properties of Recycled Aggregate Concrete

The compressive strength of recycled aggregate concrete turned lower in the early age, while the 28-day strength values were more comparable. The research provided insights of how recycled aggregates from various construction waste sources would affect concrete properties based on raw aggregate properties.

Research on Properties of Recycled Fine Aggregate from Waste Recycled Aggregates Concrete

Abstract: The properties of recycled fine aggregate(RFA) from waste recycled aggregate concrete (RAC) were determined. In this study, five series of parental concrete mixtures using natural coarse and fine aggregates were prepared, which had the same target ...

Effects of Recycled Aggregate on Concrete Mix and Exposure to

Concrete mix with 30% recycled aggregate had the lowest chloride penetration after 2 weeks of saturation and performed better than a concrete mix with 100% natural aggregate. Owing to the lower density and higher water absorption of recycled aggregates, chloride ion diffusion increased with increasing recycled aggregate content beyond 2 weeks.

(PDF) Durability of recycled aggregate concrete

A lot of research has already been done on the mechanical properties of recycled aggregate concrete. This led to some changes in the standard for various applications. These authorized application remain quite low risk (Indoor, no frost, …). The

PAPER OPEN ACCESS Non-Destructive Testing of Recycled

Abstract. Currently, recycled aggregate concrete is a widely used building material. Due to negative influences on concrete’s mechanical properties, it is mostly used in low-valued applications. Nevertheless, high quality recycled concrete aggregates derived from a good

Use of Recycled Aggregate in Concrete

In this research, Recycled Coarse Aggregates (RCA) from demolished slab pieces were used. These demolished slab pieces are crushed to suitable size and reused as recycled coarse aggregate. Natural sand used as fine aggregate. Concrete industry, uses 12.6 billion tons of raw materials each year, is the largest user of natural resources in the world.

Recycling of Brick Aggregate Concrete as Coarse Aggregate

Jul 07, 2015 · 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.
