“…The re duc tion in the com pres sive strength can be at trib uted to the dilu tion ef fect on the ce ment and also the ac cu mu la tion of the biochar par ti cles. These find ings are sim i lar to that of Khush nood et al [ 119 ], Ah mad et al [ 126 ] and Fal liano et al [ 158 ] where the in cor po ra tion of a higher con tent of biochar was re ported to have a con se quen tial ef fect on the flex ural strength. How ever, in con trast to the con ventional sup ple men tary ce men ti tious ma te ri als such as sil ica fume, no sig nif i cant ef fect was found when rice husk biochar was in cor po rated into mor tar mix tures due to its lower poz zolanic re ac tiv ity [ 42 ].…”

With in creas ing pop u la tion and ris ing de mands for im proved built en vi ron ment, there is an ex pected in crease in green house gas emis sion from the con struc tion in dus try. Car bon diox ide emis sion lev els are fast ap proaching a tip ping point which could lead to ir re versible cli mate change. The earth's ca pa bil ity to neu tralise the CO 2 emis sions through the nat ural car bon cy cle has been over stretched. There fore it is im per a tive to adopt technolo gies that are able to cap ture and se quester CO 2 in or der to can cel out their re lease from in dus trial ac tiv ities such as the con struc tion and build ing in dus try. This is im por tant so that ce ment-based ma te r ial pro ductions' car bon foot print can be re duced dras ti cally for a pos i tive change to take place in the cli mate. Biochar holds great promise as an ef fec tive CO 2 sorp tive ma te r ial in ce ment-based ap pli ca tions rel a tively sim i lar to its con ven tional use for soil amend ment. Ac tu ally, frag mented re searches on biochar as an ad mix ture in ce men titious ma te ri als have been con ducted. Based on this logic, this re view placed enor mous em pha sis on col lat ing in for ma tion from re cent stud ies on biochars from agro-sources used as an ad mix ture in ce ment-based ap pli cations. Sim i larly, the re view gave up-to-date knowl edge about the sources of the bio mass and the pro duc tion processes. Con clu sively, the pos i tive ef fects of biochar for car bon se ques tra tion on some prop er ties of the var ious ce men ti tious ap pli ca tions were high lighted.

“…This leads to improvements in durability, shrinkage, cracking and mechanical properties (Akinyemi and Adesina 2020). In addition, the literature generally reports structural benefits in association with biochar incorporation into cement-based composites, where improvements in mechanical properties, such as compressive and flexural strength as well as ductility and general toughness, are documented (Choi et al 2012b;Restuccia and Ferro 2016;Khushnood et al 2016;Ahmad et al 2015). Reduction in setting times as well as enhanced durability have also been reported (Akinyemi and Adesina 2020).…”

Industrial biochar systems for atmospheric carbon removal: a review

et al. 2021

In the context of climate change, there is an urgent need for rapid and efficient methods to capture and sequester carbon from the atmosphere. For instance, production, use and storage of biochar are highly carbon negative, resulting in an estimated sequestration of 0.3–2 Gt CO2 year−1 by 2050. Yet, biochar production requires more knowledge on feedstocks, thermochemical conversion and end applications. Herein, we review the design and development of biochar systems, and we investigate the carbon removal industry. Carbon removal efforts are currently promoted via the voluntary market. The major commercialized technologies for offering atmospheric carbon removal are forestation, direct air carbon capture utilization and storage, soil carbon sequestration, wooden building elements and biochar, with corresponding fees ranging from 10 to 895 GBP (British pounds) per ton CO2. Biochar fees range from 52 to 131 GBP per ton CO2, which indicates that biochar production is a realistic strategy that can be deployed at large scale. Carbon removal services via biochar are currently offered through robust marketplaces that require extensive certification, verification and monitoring, which adds an element of credibility and authenticity. Biochar eligibility is highly dependent on the type of feedstock utilized and processing conditions employed. Process optimization is imperative to produce an end product that meets application-specific requirements, environmental regulations and achieve ultimate stability for carbon sequestration purposes.

“…Some of the durability tests, including chloride penetration, water permeability and absorption, gas permeability, carbonation, electrical resistivity, sulfate attack, acid attack, frost resistance, and scaling, have been investigated [ 17 , 19 , 23 , 44 ] and more especially the fire resistance, cooling methods, weight loss, and residual mechanical properties of SCC [ 5 , 45 , 46 , 47 ]. Only few studies were found in the literature that investigated HPSCC [ 2 , 9 , 48 , 49 ] and its optimization [ 50 , 51 , 52 ]; these studies had focused on mechanical properties with either porosity, workability, water penetration, rheological properties, exposure to elevated temperature, or one durability test; but frost or scaling resistance of SCC have rarely been investigated in the literature.…”

High-performance self-consolidating concrete is one of the most promising developments in the construction industry. Nowadays, concrete designers and ready-mix companies are seeking optimum concrete in terms of environmental impact, cost, mechanical performance, as well as fresh-state properties. This can be achieved by considering the mentioned parameters simultaneously; typically, by integrating conventional concrete systems with different types of high-performance waste mineral admixtures (i.e., micro-silica and fly ash) and ultra-high range plasticizers. In this study, fresh-state properties (slump, flow, restricted flow), hardened-state properties (density, water absorption by immersion, compressive strength, splitting tensile strength, flexural strength, stress-strain relationship, modulus of elasticity, oven heating test, fire-resistance, and freeze-thaw cycles), and cost of high-performance self-consolidating concrete (HPSCC) prepared with waste mineral admixtures, were examined and compared with three different reference mixes, including normal strength-vibrated concrete (NSVC), high-strength self-compacted concrete (HSSCC), and high-performance highly-viscous concrete (HPVC). Then, a multi parameter analytical approach was considered to identify the optimum concrete mix in terms of cost, workability, strength, and durability.
