“…The traditional ceramic materials industry is known for its wide variety of large scale products (which includes blocks, tiles, concrete, and soil) and for the consequent significant impact, in economy and jobs worldwide. [1][2][3] However, there is a great environmental liability caused in its different stages of production, and the search for constant improvement of these processes has been encouraging many researches. 4 These adverse effects to environment start from the raw materials extraction, which is a high energy consumption process, typically generating large amount solid wastes able to be used in other derived processes.…”

Cementitious ceramics, produced from the hydration of cement and hydrated lime, are responsible for a great deal of damage to the environment due to the high emission of CO 2 that occurs in the production of cement and lime. Therefore, the objective of this work was to substitute the hydrated lime with a combination of clay residue and marble waste extracted from ceramic and ornamental rock producing industries, respectively, which constitutes a circular economy for the ceramic industry related to masonry applications. Ceramics were produced in the proportion 1:1:6:1.5 (cement:lime:sand:water), through the molding procedure, and were studied by replacing hydrated lime with 100% clay residue and 100% marble residue, in addition to stoichiometric calculated parts of marble to clay. The molar ratios used were 1:1, 1:2, and 2:1 (marble:clay). Tests of consistency, incorporated air content, water retention, compression strength, density, water absorption by capillarity, adhesion, and electrical resistivity were performed. The results obtained demonstrate that the use of residue of marble and clay together, as long as they are correctly balanced, provides a high gain in technological properties, enabling the circular economy of cementitious ceramics, mainly for the composition 1 marble:1clay, which presented the best properties, both in the fresh and hardened state. The economic analysis carried out proved the financial gains for the industrial sectors involved (civil construction, ornamental rock, and ceramic).

“…Nano-SiO 2 is the most widely investigated nanoparticle [19,[51][52][53] while the effect of adding other partials such as nano-TiO 2 [22,54,55], nano-Al 2 O 3 [9,56,57], nano-ZnO 2 [58,59], nano-Fe 2 O 3 [10,60], nano-CuO [61], nano-SnO 2 , nano-ZrO 2 [62], nano-TiO 2 [63], carbon nanotubes [64], carbon nano-fibers [45], polycarboxylates [65], nano-Cr 2 O 3 [48,66], nano-clay [45] and nano-CaCO 3 [62,67] in properties of fresh and hardened concrete has been investigated so far. For example, Tawfik et al [68] evaluated the effect of nano-waste ceramic and nano-silica on the mechanical properties of hardened concrete. The obtained results showed improvement in the performance of concrete but also resolved the footprint caused by this waste.…”

Effect of Alumina Additives on Mechanical and Fresh Properties of Self-Compacting Concrete: A Review

et al. 2021

Self-compacting concrete (SCC) has been increasingly used in the construction sector due to its favorable characteristics in improving various durability and rheology aspects of concrete such as deformability and segregation resistance. Recently, the studies on the application of nano-alumina (NA) produced from factory wastes have been significantly considered to enhancing the performance, and mechanical strength, of SCC. Many experimental works show that NA can be used in SCC with appropriate proportion to enjoy the benefits of improved microstructure, fresh and hardened properties, durability, and resistance to elevated temperature. However, a limited detailed review is available to particularly study using NA to improve the performance of SCC, so far. Hence, the present study is conducted to fill the existing gap of knowledge. In this study, the effect of using NA in improving rheological, mechanical parameters, and elevated temperature resistance of SCC is reviewed. This research summarized the studies in this area, which have been different from the previous researches, and provided a discussion on limitations, practical implications, and suggestions for future studies.

“…The concrete containing 5.0% and 3.0% NSS by weight of cement content showed density values of 3,010 and 3,015 kg/m 3 respectively. The NSS content should be optimized to ensure an optimal concrete density and physicomechanical characteristics [65]. With the increasing curing period, the mass density of most mixes increased.…”

High molar mass materials (nano-silica slurry [NSS] and aggregate of steel furnace slag [ASFS]) can improve concrete shielding properties. However, only a few studies have been reported in this regard. Hence, this paper aims to determine the effect of NSS and ASFS on the properties of the resulting steel slag heavyweight concrete (SSHWC). The use of NSS in this study is a novel contribution. Furthermore, the maximum percentage of NSS to be introduced into the concrete for maximum effect was also optimized. This study also implemented an investigation program with six concrete mixtures prepared using ASFS as the primary by-product aggregate. The engineering, X-ray, and γ-ray attenuation characteristics of the SSHWC were evaluated. The results showed that the addition of NSS in SSHWC at the optimal content of 3% by weight of cement improved the X-ray shielding by 6.4%. Besides, all the concrete’s engineering and γ-rays’ properties were enhanced correspondingly.
