Highlights Drying showed a calcium carbonate production rate of 0.19 mg/h. In UV–Visible spectrometry, it was possible to differentiate the wavelength between lactate and calcium carbonates at 820 nm. The biochemical reaction demonstrated a calcium carbonate production rate of 0.40 mg/h. The limiting step of the process was drying.
Abstract Cement is the most widely used material in the world. However, a lack of maintenance of concrete structures increases the collapse danger. Against this situation, studies to recover structures are developed using biomineralizing bacteria. The aim of this study was to determine the limiting step in a prototype Cascade System for Biomineralization in Cement (CSBC) comparing crystallization to biochemical reaction by Bacillus cereus. The similar conditions of crystallization and bioreaction indicated that crystallization is the limiting step, with a carbonate production rate of 0.19 mg/h. The results obtained indicated an eco-friendly option to reduce greenhouse gas emissions.
