Reusing biochar as a filler or cement replacement material in cementitious composites: A review
Highlights Chemical and physical properties of biochar are comprehensively discussed. Engineering properties of biochar modified cementitious composites are presented. Using 2 wt% biochar can produce sound and sustainable cementitious composites.
Abstract For the past two decades, researchers are highlighting and countering the threats of environmental pollution due to the production of cementitious materials and industrial waste. The most viable attempt is to identify effective waste to be successfully incorporated in the production of cementitious materials. Biochar with its peculiar properties and sustainable benefits has the potential to be complied with construction materials. Therefore, this article comprehensively discusses the properties of biochar to evaluate its efficiency to be used as a filler or cement replacer in cementitious materials. In addition, the effect of biochar on the fresh and hardened properties of resulting construction materials has also been comprehensively documented. The results showed that using less than 2 wt% of biochar can produce cementitious materials with improved or equivalent performance like conventional cementitious materials. However, incorporation percentage can reach up to 10% by using pretreated biochar without any detrimental impact on the engineering properties of cementitious composites. Meanwhile, more research work especially on durability properties is needed to be conducted to evaluate the in-depth performance of biochar based cementitious composites.
