Cement

Cement: Powdery hydraulically inorganic cementitious material. After mixing with water, the slurry can harden in air or in water, and can firmly bind sand, stone and other materials together.

The mixture of early lime and pozzolanic ash is very similar to modern lime pozzolanic cement. The concrete made by using it to cement crushed stone not only has higher strength after hardening, but also can resist the erosion of fresh water or brine. For a long time, as an important cementitious material, it has been widely used in civil construction, water conservancy, national defense and other projects.

Cement is classified according to its use and properties as follows:

General Cement: Cement commonly used in civil engineering. General cement mainly refers to six types of cement stipulated , namely Portland cement, ordinary Portland cement, slag Portland cement, pozzolanic Portland cement, fly ash Portland cement and composite Portland cement.

Special cement: cement for special use. For example: G grade oil well cement, road Portland cement.

Characteristic cement: a kind of cement with outstanding performance. Such as: fast hardening Portland cement, low heat slag Portland cement, expanded sulphoaluminate cement, phosphoaluminate cement and phosphate cement.

Ring chain bucket elevator is suitable for conveying powdery, granular and small pieces of non-polishing and small polishing materials. Ring chain bucket elevator is a kind of ring chain bucket elevator, which uses mixed or gravity unloading and digging loading. TH ring chain bucket elevator is suitable for conveying powdery, granular and small block bottom polishing materials with stacking density less than 1.5t/m3.
