Based on the sintering property and original particle size of out-bought ore powder for sintering, lab sinter-pot tests are done with different proportioning structure, the selection order for several structures determined from the sintering course analysis and the test of metallurgical property of finished products.

Studies on hydration mechanism of slag powder cement;

With the development of cementitious material,slag powder is more used as high-performance admixture in cement and concrete.

The relationship between the slag powder content and the mortar strength of slagcement system (expression in activity index) was studied.

The influence of the ground slag by Beijing-steel Plant tothe properties of resisting cracking of concrete at early age;

For concrete containing silica fume or ground slag , the reduction of auto-shrinkage is more effective by composite aggregate .

The influence of ordingary ground slag on drying shrinkage of conrete was studied in this paper.

Influence of slag on volumetric deformation of cement motar under environment of invariable temperature and variational humidity;

The relationships of tensile-compressive-bending of concrete with micro-slag;

In this paper,some performances that included workability,compressive strength,elastic module,drying shrinkage and creep,were tested for hydraulic engineering concrete with and without fly ash or slag.

Programs were put forward according to the study on the nature of synthetical powder mineral at Huidong: + 0.

Energy saving effects of applied pressure filtration for gained powdered ore under the well;
