Abstract
Probe into Processing high Iron and Sulfur aluminic acid cement is a kind of energy saving high type new variety cement.Mainly contain SiO
25-10% (weight percent, following same).Al
2O
3(10-20%), Fe
2O
3(9-15%), CaO (35-55%) and SO
2(5-15%) component such as MgO (0.1-2%) when characteristics of the present invention are to adopt above-mentioned proportion scheme, burns till the high quality cement clinker of rapid hardening high-strength low energy consumption under 1000 ℃-1200 ℃.
Description
A kind of sulplo-aluminate type cement, this cement has higher early strength and later strength, and setting time is short, is applicable to various structures or s.
Sulphate aluminium cement is by containing SiO
2, Al
2O
3, Fe
2O
3, CaO, MgO, SO
3Deng the raw material of component through batching, mixing, grinding, the technical process manufacturing such as burn till and obtain.
Its mineral composition is generally calcium sulphoaluminate (C
4A
3S), tetra calcium aluminoferrite (C
4AF) dicalcium silicate (C
2S) etc.
The characteristics such as this kind cement has early strong, and is fast hard, but owing to require more Al when making
2O
3, must consume more bauxite mine, other firing temperature higher (about 1300 ℃), so cost is higher, has hindered its extensive use.
The invention provides a kind of sulplo-aluminate type cement of new composition, further reduce firing temperature, reduce the consumption of bauxite ore, reach energy-conservation, the purpose that reduces cost.
Aluminate cement with high iron and surfur content of the present invention is on the basis of sulphate aluminium cement, further increases Fe
2O
3Consumption, make Fe
2O
3Content surpasses 9% scope that reaches 9-15%, and the content of corresponding other component of adjustment, burns till under 1000 ℃-1200 ℃ of low temperatures more.The charge ratio of this cement, difference according to the difference of feedstock property and slightly, general control consists of SiO
25-10%, Ai
2O
310-20%, Fe
2O
39-15%, CaO35-55%, SO
35-15%, MgO0.1-2%(raw material) all the other are impurity component.
This cement has early strong, fast hard, the characteristics such as cost is low.Figure is the SiO that consists of that burns till under 1040 ℃ of temperature
28.72%Al
2O
315.5%, Fe
2O
311.2%, CaO38.6%, SO
3The grog X-ray diffracting spectrum of 7.54%, MgO1.26%.
This strength of cement is higher than 500kg/cm
2(7 days).
Claims (2)
1, a kind of sulphate aluminium cement contains SiO
