2021-4-15 Concrete made with DCBs and SCC was denoted as DCB-filled-concrete (DCBFC) in this study, which is similar to rock-filled concrete (RFC) used in massive concrete construction in China (An et al., 2014). This study explored the feasibility of using DCBs in concrete production and investigated the mechanical performances of DCBFC, in particular ... ...
2018-10-3 Using recycled concrete from demolished buildings as an aggregate in new concrete preparation can have a significant role in the sustainable development of the concrete industry; therefore, in this research work, the effect of employing different percentages (i.e., 20, 40, 60, 80 and 100%) of recycled concrete aggregates and the impact of using ... ...
2017-12-30 This research focuses on studying the fresh state behaviour of self-compacting recycled concrete (SCRC) using rheology as a fundamental tool. For said purpose, a reference self-compacting concrete (SCC) was designed and it was modified to obtain other two SCCs with different water to cement ...
2015-11-15 In this research, the recycled coarse aggregates (RCAs) and/or recycled fine aggregates (RFAs) obtained from crushed concrete specimens were used as a replacement for natural coarse aggregates (NCAs) and/or natural fine aggregates (NFAs), respectively to produce self-compacting recycled aggregate concretes (SCRACs). ...
This study evaluated the influence of the Portland cement replacement by 0, 5%, 10%, 15% and 20% of Construction and Demolition Waste (CDW) filler contents in the production of self-compacting concrete (SCC). The SCC mixtures were evaluated on fresh state by slump flow, J-ring, resistance of segregation, specific gravity, and on hardened state by compressive and splitting tensile strength ... ...
2019-2-25 J, an international, peer-reviewed Open Access journal. Aims: Dear Colleagues, The subject of self-compacting concrete with recycled aggregates is greatly relevant to society, since there is an increasing demand from the recycled aggregates construction industry to adopt new processes to minimize its negative impacts on the environment. ...

2021-7-13 Clay brick is one of the major components of demolition waste, which is generally landfilled. Effective and new uses of recycled clay brick may provide sustainability benefits in terms of landfill reduction. Therefore, this research aims at applying Recycled fine clay brick aggregates (RFCBA) with sizes from 0.075 mm–4.75 mm to prepare Self-compacting concrete (SCC). The effects of RFCBA on ... ...
In order to study the mechanical performance of self-compacting reinforced concrete beam with recycled coarse aggregates, recycled concrete and recycled gravel were taken as coarse aggregates with the particle size from 50 to150mm, two groups of specimen of self-compacting reinforced concrete beams with recycled coarse aggregates were made. ...

It is studied the effect of binder quantity, water binder ratio on properties of self-compacting concrete made with recycled coarse aggregates. It can be prepared C50 self-compacting concrete made with recycled coarse aggregate by adjusting send proportion, binder quantity, and mixing mineral additive. For example, when the binder quantity is 600 kg/m3, water binder ratio is 0.28, the flexural ... ...
In order to study cubic compressive strength of recycled coarse aggregates-filled concrete systematically, recycled coarse aggregates with the particle size from 50 to150mm are made from waste solid contents, which are artificially broken from abandoned rubble and concrete blocks. Based on the mix proportion design method of ordinary concrete and test code for hydraulic concrete, 3 groups of ... ...
Self-compacting concrete is absent of vibration noise during casting, improves the construction efficiency, and provides a healthier working environment compared to the traditional vibrated concrete. The potential coarse recycled aggregate obtained from crushed concrete for making self-compacting concrete was considered to replace the aggregate with the percentage of substitution of recycled ... ...
2019-8-25 Abstract. The paper herein presents the results of an experimental work carried out to investigate the rheological behaviour of self-compacting concrete (SCC) mixes, which were produced by replacing natural sand with recycled fine aggregate (RFA) ...
