The results indicated that the polyhydrate binding material can produce higher binding strength under lower dosage compared with the ordinary cement, so it is applied to cement total gold tailings.
This rock contained chalcedonic cement before it underwent diagenesis, a process where low temperatures and low pressures alter the content of sediments before they finally lithify, or turn into rock.
A series of laboratory cementing experiments on the total tailings from a gold mine in Shandong Province were conducted by use of ordinary cement and polyhydrate material as binding materials.
The obtained achievement in building material industry is studied, including sintering cement with substituting coal by cokeite and smelting rockwool with substituting coke by cokeite and so on.
The expansion mechanism of hydroxide expanding phase for oil well cement slurry are discussed on the basis of principle of chemical thermodynamics and topochemical reaction model.
The alabandite and getchellite of hydrothermal origin, cement anatase of alkaline volcanic origin, and the high content of chlorite in coal were fist found in coals.
The overlay of asphalt concrete on the cement concrete road is a special pavement construction, and the stress-diversification has biggish difference from normally flexibility samdwich system.
Aerocrete building block product to replace non-burning and cement brick building block for building wall body top of products of material of products finally too.
The characteristics of each cement clinker process by carbide slag in domestic were analysed. dry prebaking, dry grinding, and dry burn process are best prospective.
Main products include: auto dry-mixing facility for oil well cement, no-subpressure remote monitor and control water supplying equipment, electrical sets and automation instrument.
The characteristic and distinguished method of two classificatory cemented carbide binder is expatiated.It is recommended that GBY is a new cemented carbide binder.
Grainstones are the main part of the section, among which the oolites, intraclast limestones and most bioclast limestones are cemented by sparry calcite.
