Bulk cement & clinker carried in conventional bulk

2019-1-25 · Bulk cement & clinker carried in conventional bulk carriers Cement clinkers are unground cement which is shipped as such to avoid the difficulties of carrying cement powder. Cement carriers – are single-skin or double-skin bulk carriers provided with a cement loading and discharging plant. Most vessels of this type use the principle that when air is pumped through a cement cargo, it acts as if it

Conventional Cement - an overview | ScienceDirect

In conventional cements, the slurry and set-cement properties depend on the slurry density (water-to-solids ratio) and the additives. For engineered particle size cement systems, the slurry and set-cement properties depend upon the properties of added inert solids, the packing volume fraction of the solids and cement and the solid volume fraction of the resulting slurry.

Hoffmann Green Cements: first

The manufacture of conventional cement is very polluting. In particular, it requires a lot of energy to produce clinker, the main component of cement. To reduce its carbon footprint by 80% by 2050, the cement industry must therefore innovate. Hoffmann Green is fully committed to this mission. Decarbonated cement 0% clinker is already an accessible reality.

What is Cement Clinker? Composition,

2021-3-9 · Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...
