· Anhydrite influenced the reaction degree at the early age more significantly than did limestone, probably due to greater solubility of sulphates than carbonates and resulting undersaturation of aluminium. The distinct contribution of the composite anhydrite-limestone mix to GGBS hydration became apparent after 1 day.

Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) derived from the remains of ancient marine organisms such as coral, shells, and microorganisms. Over millions of years, these organic materials accumulate and undergo compaction and cementation to form limestone deposits.

· On the Mohs hardness scale, which measures the ability of a mineral to resist scratching, quartz rates a 7, while calcite rates only a 3. This means that quartz can scratch calcite, but calcite can’t scratch quartz. You can perform a scratch test using a common steel nail, which has a hardness of about 4.5.

Crystalline limestone is a carbonate sedimentary rock that is composed of the precipitation of the mineral calcite ( CaCO3 CaCO 3) from saturated sea water. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate ( CaCO3 CaCO 3 ). About 10% of sedimentary rocks are limestones.
