  Concrete is the second most consumed product by humans, after water. However, the production of conventional concrete causes more than 5% of anthropogenic CO2 emissions and therefore there is a need for emission-reduced construction materials. One method to produce a solid, concrete-like construction material is microbial-induced calcium carbonate precipitation (MICP). To get a better understanding of MICP it is important to be able to follow local pH changes in dissolution and precipitation processes of CaCO3. In this work we present a new method to study processes of MICP at the micro-scale in situ and in real time. We present two different methods to monitor the pH changes during the precipitation process of CaCO3. In the first method, the average pH of small sample volumes is measured in real time, and pH changes are subsequently correlated with processes in the sample by comparing to optical microscope results. The second method is introduced to follow local pH changes at a grain scale in situ and in real time. Furthermore, local pH changes during the dissolution of CaCO3 crystals are monitored. We demonstrate that these two methods are powerful tools to investigate the pH changes for both MICP precipitation and CaCO3 dissolution for knowledge-based improvement of MICP-based material properties.

  Soluble organic acids are constantly supplied to soils as a result of the oxidative decomposition of organic matter by the plant roots and microorganisms. These carboxylic group-bearing organic molecules can interact with soil clay minerals and affect the formation and stability of organomineral aggregates. While it has been suggested that –COOH laden organics can strongly bind to broken clay edges, less is known about how such soluble acids interact with negatively charged basal clay surfaces. This work presents a Surface Forces Apparatus (SFA) study of interactions between two mica surfaces in dicarboxylic acid molecules with 2 to 7 carbon atoms. SFA allows measuring nanoscale surface forces acting between macroscopic surfaces as a function of surface separation. Since, unlike as in atomic force microscopy, the absolute surface separation in the SFA is known, it is possible simultaneously probe the adsorption of dicarboxylic acids onto mica. The results show that significant amounts of dicarboxylic acids can adsorb on mica surfaces, but only in the presence of Ca2+ ions. Ca2+ acts as cationic bridges between the negatively charged mica surface and deprotonated –COO- functionalities. In addition, the multilayer binding of larger dicarboxylic acids (C5-C7) via an assembly of hydrophobic chains is resolved. Na+ does not promote any substantial dicarboxylic acid adsorption and induce strong repulsion between mica surfaces. In summary, although these face-specific SFA measurements show that dicarboxylic acids adsorb onto mica basal surfaces only by weak forces including electrostatic, hydrophobic, and likely hydrogen bonding, they demonstrate that even such weak outer-sphere adsorption can affect adhesion between clay surfaces and play a role in the organomineral aggregate formation.
