🚨 PAPER 🚨

A viable & novel formula for a #CarbonNegative, environmentally friendly #concrete that is nearly as strong as regular concrete has been developed recently at Washington State University.

#Concrete
#Biochar
#CarbonSequestration

*Summary* in a🧵 below:
1/6

🧫 Researchers exemplify "a synergistic C-capture strategy, i.e., using #concrete washout water & #biochar together to achieve carbon-negative concrete."

"This strategy enabled the biochar to #capture 22.85 wt% air-borne CO2, which precipitated CaCO3 onto the biochar."

🔬"This carbon-negative cement paste consisted of 30 wt% CO2-weathered #biochar and 70 wt% portland limestone #cement, which achieved the 7-day and 28-day compressive strengths of 22.1 MPa and 27.6 MPa, respectively," microscopic investigation revealed.

Here is a video that highlights the reduced lumber requirements for building with hempcrete: #Sustainable #SustainableHomeBuilding #EnergyEfficient #CarbonNegative #Agriculture #FarmRaised #SaveTheTrees

#Hempcrete Building Code approval applies to one- or two-family dwellings and townhouses plus should increase the availability of hemp-based building materials and facilitate greener construction projects around the U.S. source: #Gangapreneur
