Calcite with different fineness is widely used in papermaking, medicine, chemistry and agriculture. Heavy calcium is closely related to people's lives. In the past decade, globally, the annual production capacity of heavy calcium increased by 5%-8% on average, while that of China 10%. Calcium carbonate powder processing is still an emerging ...

Calcite affects the mineralogical variant of the AFm phase(s). Calcite additions affect the amount of free calcium hydroxide as well as the balance between AFm and AFt phases, although C–S–H is unaffected in much of the range of compositions. ... interground with clinker to cement fineness but may be much slower with limestone …

The unreacted calcite together with white mica, magnetite phases would become the primary aggregate in the AAC samples [22]. ... The appropriate content and fineness of iron tailing in preparing AAC could be 27–34% mass ratio of the total weight and particle size under 80 ...

It is concluded that the fineness of clinker and limestone is strongly connected with the limestone content and the fineness of the cement. ... Ordinary Portland clinker of industrial origin and limestone of high calcite content (CaCO 3: 95.3%) were used (Table 1, Table 2). Four clinker/limestone mixtures, containing 10%, 20%, 30% and 40% ...

The increase of specific surface area is rather important for the calcite grinding in distilled water with the two polyelectrolytes since the fineness efficiency factor is nearly equal to 2. When a sufficient amount of polyelectrolyte is added, the suspension remains stable with regards to aggregation phenomena.

Therefore, the speed of consumption of portlandite corresponds to the early rate of pozzolanic reaction. Calcite production depends on the presence of portlandite therefore, it was assumed that, if calcite was being formed, portlandite was still available and thus the pozzolanic reaction still active. 2.4.2 Mechanical activity index

A dormant period (HF = 0) differs from the induction period (HF > 0) as the heat flow is completely reduced to zero. The duration of this period can be influenced by the grain size, as well as quantity and type of filler used (including calcite) [37]. For example: with increased calcite fineness the dormant period (II) is shortened.

The most stable surface of calcite is the rhombic face, which results from the broken bonds between Ca and CO 3 ions.
