Properties of concrete made with recycled coarse aggregate ...

05/11/2013  Waste brick was used to replace natural aggregate after being treated, called recycled coarse aggregate (RA). Furthermore, fly ash was used as 0, 10%, 15%, and 20% by weight replacements of cement. Workability was evaluated through slump and cohesiveness testing, and results implied that the concrete samples showed good workability except the mix containing 40% RA.

Application of recycled concrete aggregates as alternative ...

Three different types of coarse aggregates were used in this series of tests as granular infills. The hollow cores between the blocks were infilled with natural coarse aggregates (NCAs) and two different types of recycled concrete aggregates (RCAs). The recycled aggregates were produced by crushing 30 grade

Results clearly show that, the recycled sands possessed significantly higher cement paste content and higher water absorption than coarse RCA. Then, concrete blocks with different substitutions (0%, 30%, 100%) of natural aggregate by the same volume fraction of RCA were manufactured. The fresh properties (slump, density, air content), and ...

A Study of Concrete Made with Fine and Coarse Aggregates ...

This paper deals with the possibility of using fresh concrete waste as recycled aggregates in concrete. An experimental program based on two variables (proportion of fine aggregates replacement and proportion of coarse aggregates replacement) was implemented. The proportions of replacement were 0%, 50%, and 100% by mass of aggregates.

14/06/2021  Typical effects of coarse and fine aggregates on the long-term properties of sea sand recycled aggregate concrete (SSRAC) are analyzed by a series of axial compression tests. Two different types of fine (coarse) aggregates are considered: sea sand and river sand (natural and recycled coarse aggregates). Variations in SSRAC properties at different ages are investigated. A
