Relevant biochar characteristics influencing compressive strength of biochar-cement mortars

Abstract

•	A broad selection of biochars were used to replace 10 wt.% cement in mortars, resulting in similar or improved strength.
•	Biochar moisture saturation percentage, O/C, and soluble silicon are the most important predictors of mortar strength.
•	The data support the hypothesis that biochar improves strength via internal curing, found to be the most important mechanism.
