Hybrid assays for predicting biofilm-induced concrete deterioration
Innovative hybrid assays to quantify biofilm growth and its impact on concrete deterioration, aiming to predict microbially-induced corrosion (MIC) in infrastructure by correlating biofilm activity with material degradation.
Overview
This solution offers innovative hybrid assays designed to quantify biofilm growth and its impact on concrete deterioration. These assays aim to predict microbially-induced corrosion (MIC) by correlating biofilm activity with material degradation metrics such as mass loss, surface roughness, and compressive strength reduction. By providing a deeper understanding of the mechanisms behind MIC, these assays help in developing predictive models for assessing the long-term performance of concrete in infrastructure.
Technical specifications
Key features:
- Measures biofilm biomass through protein concentration and imaging analysis.
- Assesses concrete deterioration via compressive strength, surface roughness, and mass loss.
- Correlates biofilm metabolic activity, including pH changes and organic acid production, with material degradation rates.
- Utilizes standardized concrete specimens and bioreactors to replicate various environmental conditions.
- Analyzes microbial communities using DNA sequencing and assesses degradation using SEM and profilometry.
Technology readiness level
The hybrid assays are currently at Technology Readiness Level 3, with ongoing validation and optimization in simulated field-like conditions. Experimental setups, data collection, and integration processes are being refined to enhance predictive accuracy. Future plans include field testing to ensure robustness and reliability in real-world scenarios.
