The Expansion Cracks of Dolomitic Aggregates Cured in …

Therefore, dolomite reacted with TMAH and caused the concrete microbars and rock prisms to expand, and the contribution of the ACR to expansion was carried out later. Based on microscopic analysis, expansion cracks were generated in the dolomite enrichment area, and dolomite crystals with different particle sizes were distributed at the crack origin as well as around the crack.

The band positions of calcite-dolomite mixtures in the SWIR and TIR regions were determined by the quantity of calcite and dolomite in the sample. These results can be applied for the identification of pure and mixed calcite and dolomite, as well as estimating the relative abundance of both minerals with different grain size and mineral mixtures in a synthetic sample or rock.

Dolomite is found in extensive beds as a compact limestone or dolomite rock. It is also precipitated directly from seawater, possibly under warm shallow conditions. Siderite is often found in impure form in beds and nodules (of clay ironstone) in clays and shales and as a directly precipitated deposit partly altered into iron oxides.
