Description
Technical field
The present invention relates to the production method of a kind of cement, particularly relate to a kind of low cost, the anti-seawater corrosion of energy-conserving and environment-protective
The production method of green ecological.
Background technology
Cement(cement) word is developed by Latin caementum, is the meaning of rubble and slabstone.Going through of cement
History can trace back to Calx and the mixture of volcanic ash that roman uses under construction, this mixture and modern times the earliest
Lime pozzolanic cement is much like.The concrete made with its cementing rubble, after hardening, not only intensity is higher, and can also support
Anti-fresh water or the erosion of brackish water.For a long time, it, as a kind of important Binder Materials, is widely used in architectural engineering.
1756, Britain engineer J. Si meter Dun found when studying the characteristic that some Calx hardens in water: hydraulic stone to be obtained
Ash, it is necessary to use the limestone containing clay to fire；For the masonry mortar of submerged structure, optimal composition is by water
Hydraulic lime and volcanic ash are made into.Theoretical basis has been established in development and the development of what this was important be found to be cement in modern age.1796
Year, Englishman J. Parker has burnt out a kind of cement with marl, and outward appearance is brown, like Calx and the fire of ancient rome era
Mountain ash mixture, named Roman cement.Because it is to use natural marl to make raw material, directly fires without dispensing and form
, therefore have another name called Parker's cement.There is the good hydraulicity and fast solidifying characteristic, be particularly well-suited to the engineering contacted with water.1813,
The civil engineer of France finishes to add and is found that Calx and clay are best by three to one cement performances being mixed.1824, Britain
Builder J. A Sipuding achieves the patent right of Portland cement.He is raw material with limestone and clay, by a certain percentage
After cooperation, mature calcined material in the shaft kiln being similar to burnt lime, then make cement through levigate.Because of the color after hardening of cement
Similar for the stone of building to Portland place on island, England, it is named as Portland cement.It has excellent building
Performance, is with historically new significance in cement history.1907, France's ratio angstrom utilized the red bauxite of aluminum ore to replace clay, mixing
Limestone has been fired into cement.Owing to this cement contains substantial amounts of aluminium oxide, so being called " alumina cement ".1871, day
This starts to build cement plant.1877, the Crampton of Britain invented rotary furnace, and reforms into through blue Pehanorm in 1885
Preferably rotary furnace.1889, near Kai Ping colliery, Hebei China Tangshan, set up the Tangshan " thin spongy soils " produced with shaft kiln
Factory.On the basis of this factory, within 1906, establish Qi Xin cement company, produce cement 40,000 tons per year.1893, the remote rattan show row of Japan
