A large quantity of blast furnace slag discharged in Laiwu Steel Company causes serious environmental pollution.

Replacement of pebbles with blast furnace slag for roadbed and road base cannot only solve the problem of transportation and construction cost,but can solve the problem of pollutions caused by abandoned blast furnace slag,which is significant for the alleviating material shortage,increasing the value of slag,comprehensive utilization and protection of the ecological environment.

In view of both the understanding of the double-interface sealing system and the basic analysis of the chemical and physical properties of blast furnace slag(BFS),a set of experimental facilities was developed for the simulation of interfacial bonding in cementing,and experimental evaluation was conducted on the performance of blast furnace slag cement system by bond strength simulation test.

The flyash and slag, with standard sand as aggregate, were used as principal mat erials to prepare mineral polymer.

Glass-ceramic was made from the slag of Bao-Steel Corporation in Shanghai by body crystallization.

The method of preparing slag micro-crystallographic foamed glass by using blast-furnace slag,fly ash and waste glass as the main raw materials was discussed based on the composition range of micro-crystallographic foamed glass.

In the mixture with sulphur-rich tailings, the hydration reaction of blast-furnace slag has been studied by IR, XRD and SEM in order to understand the formation dynamics of ettringite.

A comparison study has been made between the properties of blast-furnace slag powders (BFSP) ground in a φ750 mm×2 500 mm closed ball mill and in a vertical mill, respectively.

Study on the relationship between particle size distribution and powder characteristics of ground granulated blast furnace slag;
