AI Technical Summary

Technical Problem

Existing biocementation processes face challenges in producing complex shapes with consistent cementation and face issues of air gaps and low reagent flow, leading to inconsistent products and potential damage from high pressures.

Method used

The use of pluralities of inlets and outlets in a framework, combined with controlled fluid flow against gravity and pressure greater than atmospheric pressure, along with real-time adjustments based on backpressure and conductivity changes, ensures uniform cementation and enhanced mechanical properties.

Benefits of technology

This approach allows for the production of complex shapes with improved freeze-thaw properties, increased flexural strength, higher densities, and lower porosities, resulting in construction materials with enhanced compressive strength.

Abstract

Described herein are novel methods, reusable frameworks, and systems for producing building materials, structural materials, and concretes. The methods include adding a plurality of aggregate particles to a framework, thereby forming a framed plurality of aggregate particles, flowing a first fluid comprising cementation reagents through the framed plurality of aggregate particles or flowing the first fluid through the framed plurality of aggregate particles at a pressure greater than atmospheric pressure, wherein the fluid is introduced to the framework from a direction such that the flow operates against the force of gravity, and reacting the cementation reagents with a biological organism and / or an enzyme comprised within the fluid or within the framed plurality of aggregate particles for a sufficient time to consolidate the framed plurality of aggregate particles, thereby forming the construction material.
