The present invention relates to no first-hand datum high-performance cements prepared by a kind of metallurgical slag.
No first-hand datum high-performance cement composition is as follows：In parts by weight
The weight ratio for wherein handling slag and grain slag is 1：2.8~3.2.
Slag is the by-product that a kind of steelmaking process generates, it is by impurity such as silicon, manganese, phosphorus, sulphur in the pig iron in melting
Various oxides and these oxides made of aoxidizing in the process are formed with the salt that solvent reaction generates.Slag usually contains
There are 2~8% metallic irons, 40~60% calcium oxide, 3~10% magnesia, 1~8% manganese oxide by weight.Slag object includes mutually
Tricalcium silicate, dicalcium silicate, monticellite, calcium and magnesium rhodonite, dicalcium ferrite, RO (magnesium, iron and manganese oxides, i.e., by FeO,
The solid solution that MgO and MnO are formed), free calcium oxide (f-CaO) and magnesia (MgO) etc..
Slag contains tricalcium silicate similar with portland cement clinker, dicalcium silicate hydraulic cement mineral, therefore is referred to as
The Portland clinker of burning.Since it meets cement characteristics, production clinker-free cement, cement with little clinker may be used as
Raw material and cement admixture.Slag cement has wear-resisting, tension, High anti bending strength, corrosion-resistant, freeze proof, impervious etc. excellent
Characteristic.
But there is stability and be difficult to grind in slag.The principal element for influencing stability is free calcium oxide
And free magnesium, they are easily expanded after meeting water, especially free calcium oxide, it meets volume expansion 98% after water.Moreover,
They go back and CO2Reaction, causes slag rapid curing in a short time.If slag is just used as building materials without stabilization processes,
Using loose building product, bulge, deformation and cracking can be caused shortly after, after the unequal calamity in the roads Lou Daoqiaota can be brought
Fruit.Dicalcium silicate and tricalcium silicate crystallizable mineral in slag is complete, and coarse grains are fine and close, are that slag is difficult to levigate basic original
Cause.Fine grinding processing not only reduces ground-slag particle, increases its specific surface area, makes the free calcium oxide in ground-slag and free magnesium
Further aquation is accompanied by slag lattice structure and the variation of surface physical and chemical performance, makes grinding energy to improve ground-slag stability
It is converted into the interior energy and surface energy of ground-slag, promotes slag gelling.Therefore, by slag fine grinding, particle size reduction is very must
It wants.
In the present invention, slag using CN101280346B description method processing, solve above-mentioned slag stability with
Grind difficult problem.The iron content of processing slag in this way is by weight 0.05%~0.30%.If the iron of processing slag contains
