Physiochemical characterization of agricultural waste biochars for partial cement replacement

What is it about?

Portland cement production involves high energy consumption and pollutes the environment. Therefore, partially replacing cement with agricultural waste bio-chars can slow down these negative environmental impacts. Bio-chars accelerate setting, but reduce strength and water resistance. We show that under optimum conditions some agricultural wastes can be used to replace Portland cement; however, there are certain properties that make some bio-chars better suited for partial cement replacement.
