Mar 03, 2019 · However, only a few experimental tests have been conducted on recycled aggregate concrete (RAC) beam–column joints. This paper presents an experimental investigation of the seismic behavior of various types of RAC beam–column joints.

Moreover, the discussion about recycled aggregate usually correlate with recycled coarse aggregate. Coarse recycled concrete aggregate (RCA) is produced by crushing the demolition waste of at least 95% by weight of concrete, and having a total contaminant

The second task was directed towards evaluation of concrete portieres produced with fine and coarse recycled aggregate. Several concrete mixes were prepared with combinations of different aggregate grades and the results were compared to that of a control

His research interests include structural reliability, recycled aggregate concrete, safety assessment of existing reinforced concrete structures by means of NDT, identification of damage in reinforced and prestressed concrete structures through dynamic te

This paper presents a review of the literature published so far on the use of fine aggregates from construction demolition waste used as a partial or total replacement of fine natural aggregates in concrete production. The review presents the initial work

One such material is recycled aggregate concrete. Fig. 1 Concrete debris. Manufacturing of Recycled Aggregate. Recycled aggregate concrete (RAC) is produced in three major steps: Evaluation of Source concrete: The first step in production of RAC is to det

The states that do use recycled concrete aggregate in new concrete report that concrete with recycled concrete aggregate performs equal to concrete with natural aggregates. Most agencies specify using the material directly in the project that is being rec

Although the researches on recycled aggregate concrete (RAC) has been going on for nearly 70 years , the use of RA in concrete structures is still limited due to its long-term durability concerns. With the decrease of natural aggregate resources and the i

No significant increase in the strength of recycled aggregate concrete was obtained by reducing the W/C ratio below 0.40. It is indicated that the quality of recycled aggregate concrete will improve with the quality of recycled mortar or if the recycled m

Sep 09, 2016 · The mechanical study shows that the reduction rates of the compressive strength, Young’s modulus, and the Poisson’s ratio of the geopolymeric recycled aggregate concrete (GRAC) specimens increase with the increase of the water/cement (w/c)
