Problems solved by technology

However, compared with cement, the strength of mineral powder in the early hydration process is lower, and due to the limitations of factors such as low activity of slag, poor grinding performance, and poor stability, the use of mineral powder has not achieved the expected use effect.
[0006] Usually, the means of improving the grinding performance, activity and energy consumption of mineral powder is to add grinding aids during the grinding process, but the existing grinding aids cannot meet the performance requirements of mineral powder for the time being.

Abstract

The invention discloses a mineral powder grinding aid, and a preparation method and application thereof. The mineral powder grinding aid is prepared from the following raw materials: sulfate, aluminate, alkali metal hydroxide and itaconic acid. The mineral powder grinding aid disclosed by the invention can react with components in the slag under a water-containing condition, so that the activity and strength of the obtained mineral powder are improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a mineral powder grinding aid and its preparation method and application. Background technique [0002] The full name of "slag" is "granulated blast furnace slag", which is the waste slag produced when iron and steel plants smelt pig iron. The way to generate slag is: in the blast furnace ironmaking process, in addition to iron ore and fuel (coke), in order to reduce the smelting temperature, an appropriate amount of limestone and dolomite should be added as flux. The decomposition products of the co-solvent (calcium oxide and magnesium oxide) will melt with the waste ore in the iron ore and the ash in the coke to form a melt with silicate and aluminosilicate as the main components. On the surface of molten iron, it is regularly discharged from the slag outlet, and the granular particles formed after quenching with air or water are slag. [0003] Slag is ...
