Microstructure and Mechanical Properties of Recycled Aggregate Concrete

This study aims to conduct research about the microstructure and basic properties of recycled aggregate concrete under seawater corrosion. Concrete specimens were fabricated and tested with different replacement percentages of 0%, 30%, and 60% after immersing in seawater for 4, 8, 12, and 16 months, respectively.

Durability of crushed fine recycled aggregate concrete assessed

2020-01-22 · One of the paths taken towards the greening of concrete has been through the use of recycled aggregates as replacement of their natural counterparts. After decades of studies, the partial use of coarse recycled aggregates is considered acceptable, yet the use of fine recycled aggregates (FRAs) is highly restricted in concrete production.

Effect of Recycled Coarse Aggregate on Concrete Properties

Abstract. This research was conducted with the use of recycled aggregate as modification. In terms of the use of recycled aggregate, the percentage of recycled aggregate should be determined because the strength of concrete would not be obtained by the high percentage of recycled aggregate.The scope of study is about comparison between recycle coarse aggregate and natural aggregate in terms of ...

Recycled Concrete as Aggregate for Structural Concrete Production

Aggregates - Types of Aggregates | Coarse Aggregate, Fine

Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates.
