Granulated blast furnace slag is quickly quenched from melted slag at high temperature. Slag main the chemical composition is Si02, Ca0, A1203. Slag can be alkaline, acidic or neutral. Acid ore the slag has poor gelling property, while the alkaline slag has good gelling property. Therefore, alkaline slag should be selected as the fine powder of slag.
Its characteristics are as follows :(1) stable quality, reliable performance, mature manufacturing process and perfect quality quantity assurance system, can effectively control product quality, ensure the strength of pile concrete; (2) Bearing capacity of single pile High, unit carrying capacity price is cheap; (3) Wide selection range of design, easy to distribute pile; (4) Holding force on pile end strong adaptability to stratified fluctuating geological conditions; (5) Short construction period of pipe pile, fast construction speed, detection convenient; (6) The pile body is beatable and has strong penetrating ability; (7) Convenient transportation and hoisting, simple construction site, to the environment will not cause sewage cross flow, soil piles of adverse effects; (8) For sealing pile tip pipe pile, pile length and pile mass can be directly monitored. As the foundation, the settlement amount of pipe pile is small, which is beneficial to the quality of the project
Stable.
