Performance characteristics of recycled concrete

Use of recycled concrete aggregates (RCA) as a pavement material is one of the most sustainable engineering applications for the pavement industry. Investigation on the performance characteristics of RCA, such as elastic and plastic deformations of RCA is therefore, needed to assess RCA's application as an unbound pavement material.

2018-1-30 · Recycled aggregates are soaked for 24 h and then surface dried for mass measurement [1]. The mass difference before and after soaking to the mass before soaking is the absorption ratio. This is calculated for correlation with the mass of mortar within each aggregate (mortar ratio), as well as with the crushing stress of the natural aggregates. 3.

Characterization of Recycled Coarse Aggregate (RCA) via a ...

2014-5-20 · Recycled coarse aggregate (RCA) made from waste concrete is not a suitable structural material as it has high absorption of cement mortar, which adheres on the aggregate surface and on the tiny cracks thereon. Therefore, when using RCA made from waste concrete, much water must be added with the concrete, and slump loss occurs when transporting.

2013-12-1 · The porous characteristic of RFA increases its water absorption, leading to many microflaws formed inside the concrete (as proven in the following microanalysis). These microflaws weaken the anti-permeability of concrete and make it easy to be carbonated.

Shear Characteristics of the Interface between Recycled ...

2021-9-15 · To investigate the interface shear characteristics between various geosynthetics and recycled concrete aggregate (RCA), 30 large-scale monotonic direct shear tests were conducted. The main work was to analyse the effect of a biaxial polypropylene geogrid, a glass fiber geogrid, a warp-knitted polyester geogrid, a woven geotextile, and geonet on the interface shear properties of RCA.

Characteristics of recycled aggregate concretes produced ...

Thirty one concrete mixes made of various combinations of coarse and fine recycled aggregates (produced in Kuwait from demolition waste) were cast and tested. The possibility of producing structural grade concrete using the recycled concrete aggregates (RCA) produced in Kuwait has been investigated in this study. The cube compressive strength of these concretes was in the range from 26 to 51 ...
