Dolomite – Its Processing and Application in Iron
The basic processes in the production of dolomite are (i) quarrying of raw dolomite, (ii) preparing mined dolomite for its use by crushing and sizing, (iii) calcining of raw dolomite, (iv) processing the calcined dolomite further by hydrating to produce hydrated dolomite if required for use, (v) sintering of dolomite for its use as refractory material, and (vi) miscellaneous transfer, storage

Problems of design and construction refer essentially to large dams but may apply also to dams 10m high. Among large dams there is extreme diversity of height, storage, river flow, range of cost, purpose, foundation, and dam types. The main differences are summarized below: Number of dams over 15m according to height and dam material.

Methods of construction of Earth Dam. Hydraulicfill dams are constructed by using water for transporting the material to its final position in the dam. The material is discharged from pipes along the outside edges of the fill, and the coarse materials are deposited soon after discharge, while the lines are carried into the central pool.

DAM FOUNDATIONS. Concrete dams are constructed on rock foundations because of their enormous weight. Rock foundations have a very large load bearing capacity, resist erosion, and reduce permeability. A soil with a high permeability allows water to flow underneath the dam. With a strong foundation there are no height restrictions of RCC dams.

Try to find someone who specialises in dam construction. For example, you could ask neighbours who have had dams built if they are happy with the results. Once you have found a few dam builders, ask them to show you some of their recent work. If possible, talk to the owners of these dams and ask their opinions of the work. If you choose an

· MgO expansive agents are usually produced by firing magnesite at 800–1200 °C. But considering the reserves of magnesite and the producing technique, as well as construction far from the producing plant, the possibility of using the other magnesiumbearing minerals, such as dolomite, as raw materials to produce MgO has been considered.

In general strengths of over 35MPa or more are desirable for dams over 40m, while strengths as low as 14MPa are more suitable for dams less than 15m in height. Friability, the tendency to become a powder during crushing is important because too many fines can seriously interfere with construction.

In subsea geotechnical engineering, seabed materials are considered a twophase material composed of 1) rock or mineral particles and 2) water. [18] [19] Structures may be fixed in place in the seabed—as is the case for piers, jettys and fixedbottom wind turbines—or maybe a floating structure that remains roughly fixed relative to its geotechnical anchor point.
