| 摘要 |
The invention concerns the branch of building, namely producing of concrete and ferroconcrete articles under conditions of the plants of pre-cast reinforced concrete. A method of producing the concrete mix, which contains ferromagnetic additives, such as fly grit of thermal power stations, fire bar dust of metallurgical combines, waste of ore-dressing combines, includes treatment of fresh concrete mix in the inductor of rotary electromagnetic field. The high efficiency of electromagnetic activation of fresh concrete mixes with insignificant electric power consumption is ensured. In this case the mobility of concrete mix and compressive strength of concrete are increased. |
