“…Internationally, the short number of papers published on the effect of recycled aggregate on freeze-thaw resistance have addressed: construction and demolition waste (C&DW) (Abbas et al, 2009;Salem et al, 2003); marble (Gencel et al, 2012); tyres (Richardson et al, 2012) and ceramic materials (Jankovic et al, 2010). The present study pioneers research on the resistance to this action in recycled concrete containing sanitary ware industry waste, an area unexplored to date.…”

“…Other studies, however, showed a decline in bearing strength in concrete containing C&DW (Zhu and Li, 2009;Zaharieva et al, 2004) or clay-based roof tile or block waste (Jankovic et al, 2010;Topcu and Canbaz, 2007) as aggregate after exposure to freezethaw cycles. This discrepancy in the results can be attributed on the one hand to the compositional variability in C&DW and on the other to the effect of their quality and some of their physical properties (water absorption and fragmentation resistance) on their freeze-thaw resistance (Kevern et al, 2010).…”

“…e assessment of pozzolanic activity is typically based on a strength activity index specified by ASTM C618, which limits the sum of silicon, ferric, and aluminium oxides to be at least 70% for pozzolans [23]. Plenty of studies have shown that those oxides of CBP were beyond 70% and exhibit high pozzolanic activity [ 20,21,[23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. As shown in Table 1, the sum of silicon, ferric, and aluminium oxide of CBP exceeded 70%, which proved that CBP had high pozzolanic activity; these components will promote the formation of C-S-H (calcium silicate hydrates) or C-A-H (calcium aluminate hydrates) and thus affected the performance of mortar and concrete.…”

The application of recycled clay brick can not only solve the disposal problem of demolished solid waste but also reduce ecological environment damage caused by the excessive development of resources. Clay brick powder (CBP) exhibits pozzolanic activity and can be used as cement replacement. Recycled clay brick aggregate (RBA) can be used to substitute natural coarse aggregate. Recycled clay brick aggregate concrete (RBAC) can attain suitable strength and be used in the production of medium- and low-strength concrete. Clay brick waste as potential partial cement and aggregate replacement material is reviewed herein. Performances in terms of mechanical and durability-related properties of mortar and concrete are discussed. Understanding the properties of clay bricks is crucial to further research and applications.

“…Based on their experimental evidence, it can be stated that completely replacing the fine and coarse aggregate with RA reduces the dry unit weight of concrete masonry units by up to 25% [ 18 ]. Similarly, many other works demonstrate the impact of RBA on the characteristics of concrete (e.g., [ 19 , 20 , 21 ]). The impact of the limiting factors mentioned above on the final properties of concrete has also been researched.…”

High water absorption of recycled brick aggregate (RBA) is one of the most discussed parameters in terms of its application in the production of concrete—its influence on the amount of mixing water and, hence, the quality of the concrete, is usually considered negative. In this paper, different methods of decreasing the absorption of RBA and, consequently, the impact on the properties of concrete, are described. The RBA has been treated to decrease the water absorption capacity by impregnation approach using specific impregnators. Afterwards, the RBA samples have been dried at two different temperatures in the laboratory oven—20 and 90 °C. Concretes using 4/8 fraction of the treated RBA instead of natural aggregate (NA) have been mixed and tested. The effectiveness of the RBA treatments have been evaluated on the basis of their influence on the properties of the hardened concrete; by means of the following tests: flexural strength, compressive strength, capillarity, total water absorption capacity, depth of water penetration under pressure, and frost resistance. The method of ranking by ordinal scale has been used as it is suitable for the comparison of a large set of results, while results have been analyzed in terms of the most important technological parameter that influences the quality of the concrete-effective water content. Out of all the tested surface-treatments of RBA, treatment by sodium water glass has the best potential for reduction of the water/cement (w/c) ratio. When the effective w/c ratio is kept within standard limits, concretes containing treated RBA are possible to be specified for various exposure classes and manufacturing in practice. The experiment confirms that at a constant amount of mixing water, with decreasing water absorption of RBA, the effective amount of water in the concrete increases and, hence, the final properties of the concrete decrease (get worse). As the water absorption of the RBA declines, there is a potential for the reduction of the w/c ratio and improvement in the quality of the concrete.
