Biochar is a waste-derived material that can sequester carbon at a large scale. The development of low-carbon and sustainable biochar-enhanced construction materials has attracted extensive interest. Biochar, having a porous nature and highly functionalised surface, can provide nucleation sites for chemical reactions and exhibit compatibility with cement, asphalt, and polymer materials. This study critically reviewed the state-of-the-art biochar-enhanced construction materials, including biochar-cement composites, biochar-asphalt composites, biochar-plastic composites, etc. The efficacies and mechanisms of biochar as construction materials were articulated to improve their functional properties. This critical review highlighted the roles of biochar in cement hydration, surface functional groups of engineered biochar for promoting chemical reactions, and value-added merits of biochar-enhanced construction materials (such as humidity regulation, thermal insulation, noise reduction, air/water purification, electromagnetic shielding, and self-sensing). The major properties of biochar are correlated to the features and functionalities of biochar-enhanced construction materials. Further advances in our understanding of biochar’s roles in various composites can foster the next-generation design of carbon–neutral construction materials. Graphical Abstract

“…Chemistry includes hydrolysis, solvent extraction, and supercritical. Process physics consists of the mechanics of extraction, briquet, and distillation (Gautam & Chaurasia, 2020;Rodier et al, 2019;Savou et al, 2019). Pyrolysis produces different products (biooil, biochar, and gas); the benefits are more significant than other processes (Aini et al, 2022;Aboul-Enein et al, 2021;Varma and Mondal et al, 2017).…”

Sugarcane bagasse is one of the most abundant biomasses. This study aims to examine the characteristics of bagasse using a pyrolysis system to produce liquid, solid (Biochar), and gaseous. A fixed bed reactor was installed in pyrolysis with temperature variations from 300 to 600°C. The ultimate and proximate analysis was applied to evaluate the characteristic of bagasse. The experimental result found that the maximum bio-oil was obtained at a temperature of 550°C. Several characterizations were done, including gas chromatography and surface area analysis. The Levoglucosan compound of 78% area. The temperature effect on pyrolysis influenced the O/C ratio, H/C ratio, HHV value, and surface area of biochar. The High Heating Value was obtained from 16.698 to 18.496 kJ/kg. Biochar results indicated that the surface area, average pore size, and total pore volume are 180.3-198.0 m2/g, 1.42-4.33 nm, and 0.11-0.12 nm, respectively. The study also analyzed its composition in biochar.

“…Biochar was added to the cementitious as an internal curing agent, and it was found that prepared biochar was more efficient in internal curing on the mortar and improved the strength and durability performance of the cement mortar [5,6]. Biochar produced from sugarcane bagasse by lowtemperature cracking was used to modify cementitious materials, and it was found that the addition of biochar significantly optimized the hydration properties and reduced the thermal conductivity of the cement slurry [7]. Wood waste biochar was incorporated into the cement base as a green admixture, and it was found that the incorporation of biochar slightly enhanced the cement hydration reaction and fixed the harmful substances in the cement [8].…”

It is well known that is very important to improve the quality of cement material concerning its compressive strength and thermal conductivity, which may reduce its quantity of usage and improve the heat maintenance of a structure compared with the traditional cement. In order to improve the properties of cement and other building materials, the test pieces were prepared by incorporating rice straw biochar with different pyrolysis temperatures into cement paste, and the compressive strength and thermal conductivity were tested after curing under both wet and dry conditions. The results showed that with the increase of biochar incorporation, the strength and thermal conductivity of the test blocks were decreased, but the thermal insulation performance of them was increased, and the quality and density of the test block were reduced. Under the condition of wet curing, the strength of the test pieces enhanced greatly with the dosage of 1% and 5%. When the dosage was 1%, the strength of the wet curing test block was the highest, which was increased by 51.06% compared with the blank control. The block strength increased by 14.98%; the thermal conductivity of the test piece incorporating biochar was reduced, and the test piece with 10% of the dry curing showed better thermal insulation performance, and the thermal conductivity was reduced by 39.21%. It can be seen that the addition of biochar improves the strength of the test block and optimizes the thermal insulation performance of the cement.
