Abstract
The present disclosure provides compositions comprising modified biochar and a cement composition, as well as methods of making and characterizing such compositions, and/or technologies relating to such compositions, their production, and/or their use.
Claims16
A composition comprising:
- at least one cement composition;
- and
- a modified biochar comprising a hydrophobic agent,
- wherein the hydrophobic agent is selected from the group consisting of stearic acid, oleic acid, myristic acid and combinations thereof,
- wherein the biochar is within the range of 1 weight % to 30 weight % of a combination of the cement composition and the modified biochar,
- wherein the mean size of the modified biochar is within a range of 1 to 50 μm,
- wherein the mean size of the cement composition is within a range of 1 to 50 μm, and
- wherein the composition is piezoresistive.
5 more elements
A mortar for use in construction, wherein the mortar comprises:
- at least one cement composition;
- a modified biochar comprising a biochar and a hydrophobic agent, wherein the hydrophobic agent comprises stearic acid, wherein the modified biochar comprises from about 2 weight % to about 20 weight % of the hydrophobic agent, wherein a mean size of the modified biochar is within a range of 1 to 50 μm, wherein the modified biochar comprises from about 1 weight % to about 10 weight % of the total weight of a combination of the at least one cement composition and the modified biochar;
- and
- water,
- wherein the mortar is characterized in that the composition is piezoresistive, wherein the composition is characterized in that the composition has a 1% to 90% lower water absorption rate than the at least one cement composition.
