Abstract
Systems and method are provided for a biochar concrete. The biochar concrete includes a low carbon fraction biochar, non-biochar cementitious material, coarse aggregate, fine aggregate, and water. A mass of the low carbon fraction biochar, mass of the non-biochar cementitious material, mass of the coarse aggregate, mass of the fine aggregate, and mass of water depend on a binder fraction of the low carbon fraction biochar which is less than 70% carbon by mass.
Claims20
A biochar concrete, comprising:
- a low carbon fraction biochar, wherein the low carbon fraction biochar is less than 70% carbon by mass;
- non-biochar cementitious material;
- coarse aggregate;
- fine aggregate;
- and
- water, wherein a mass of the low carbon fraction biochar, a mass of the non-biochar cementitious material, a mass of the coarse aggregate, a mass of the fine aggregate, and a mass of the water depend on a binder fraction of the low carbon fraction biochar.
A method for forming biochar concrete, comprising:
- determining a binder fraction of a biochar, wherein the binder fraction is based on a fraction of supplementary cementitious material in the biochar;
- calculating a biochar concrete formulation including a volume of water and a mass of non-biochar cementitious material based on a target biochar dose and the binder fraction;
- and
- forming the biochar concrete using the biochar and the calculated biochar concrete formulation.
A method for forming biochar concrete, comprising:
- determining a binder fraction range of a biochar based on quantifying one or more of an atomic structure, a chemical composition, and a degree of reactivity of the biochar and determining an optimal binder fraction from the binder fraction range;
- calculating a biochar concrete formulation by treating the determined optimal binder fraction of the biochar as supplementary cementitious material and a remainder of the biochar as aggregate;
- and
- forming the biochar concrete using the calculated biochar concrete formulation.
