We reviewed existing studies of the effects of different calcium carbonate forms on cement properties and underscored the viability of utilising various alkaline wastes to produce different...
Subsequently, calcium carbonate precipitates on the surface of the recycled aggregates, forming a calcium-rich cementitious material that fills the pores and microcracks on the particle surface, thereby enhancing their …
Bio-concrete represents a different approach, in which aggregates are consolidated by calcium carbonate crystals produced through microbially-induced calcium …
These results clearly indicate that while increased SLA content in the mortar concretes leads to strength reductions, this reduction can be partially mitigated by adding small quantities of CaCO3. More studies are needed to further elucidate the impact of SLA on concrete strength and how strength reductions (if any) can be mitigated by CaCO3.
Bio-concrete represents a different approach, in which aggregates are consolidated by calcium carbonate crystals produced through microbially-induced calcium carbonate precipitation (MICP).
The improved physical and mechanical properties of carbonated granules are attributed to the formation of calcium carbonate during the carbonation process. The granules produced in this study show good potential for use as lightweight aggregates in …

To discuss the bonding mechanism of Cc-bonded RCFs, natural aggregates containing a single phase included in the RCFs, i.e., limestone powder, natural coarse aggregate (NCA), and natural fine aggregate (NFA), were used in this study.
Calcium carbonate in form of solid precipitate weakened the migration of water deep into the aggregate, hence reducing the effectiveness of process. It could, therefore, be …
The method employs heterogeneous dual‑calcium carbonate (Cc) precipitation from wet carbonation and calcium bicarbonate (Ca(HCO3)2) solution to form a Cc binder …

Calcium carbonate in form of solid precipitate weakened the migration of water deep into the aggregate, hence reducing the effectiveness of process. It could, therefore, be expected that biodeposition process carried out on the aggregate immediately after crushing would lead to better efficiency.
